Use of Estimates |  | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make certain estimates, judgments and assumptions. NuScale believes that the estimates, judgments and assumptions made when accounting for items and matters such as, but not limited to, depreciation, amortization, in-process research and development, asset valuations, equity-based compensation and contingencies are reasonable, based on information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the financial statements, as well as amounts reported on the statements of operations during the periods presented. Actual results could differ from those estimates.
Cash and Cash Equivalents |  | Cash and Cash Equivalents Cash and cash equivalents include demand deposits at financial institutions and short-term, highly liquid investments that satisfy the definition of cash equivalents.
Income Taxes |  | Income Taxes The Company is a limited liability company that is treated as a partnership for tax purposes with each of the members accounting for their share of the tax attributes and liabilities. Accordingly, there are no current or deferred income tax amounts recorded in these financial statements. Additionally, there are no tax uncertainties and no years which are open for examination by tax authorities.
SPRING VALLEY ACQUISITION CORP |  |
Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 as filed with the SEC on March 10, 2022 which contains the audited consolidated financial statements and notes thereto. The interim results for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the year ending December 31, 2022. | Basis of Presentation The accompanying audited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and of the SEC.
Principles of Consolidation | Principles of Consolidation The accompanying condensed consolidated financial statements of the Company include its wholly owned subsidiary in connection with the planned merger. All inter-company accounts and transactions are eliminated in consolidation. | Principles of Consolidation The accompanying consolidated financial statements of the Company include its wholly owned subsidiary in connection with the planned merger.

Emerging Growth Company | Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s consolidated financial statements with another public company which is neither an emerging growth company nor an emerging growth company, which has opted out of using the extended transition period, difficult or impossible because of the potential differences in accounting standards used. | Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Use of Estimates | Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. One of the more significant accounting estimates included in these condensed consolidated financial statements is the determination of the fair value of the warrant liability. Such estimates may be subject to change as more current information becomes available and accordingly the actual results could differ significantly from those estimates. | Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period.

Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have cash and cash equivalents as of March 31, 2022 and December 31, 2021, respectively. | Cash and cash equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have cash and cash equivalents as of December 31, 2021 and 2020, respectively.
Derivative Warrant Liability | Derivative Warrant Liability The Company accounts for the Warrants in accordance with the guidance contained in Accounting Standards Codification (“ASC”) 815, “Derivatives and Hedging”, under which the Warrants do not meet the criteria for equity treatment and must be recorded as liabilities. Accordingly, the Company classifies the Warrants as liabilities at their fair value and adjusts the warrants to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s consolidated statements of operations. The fair value of the Public Warrants has been estimated using the Public Warrants’ quoted market price. As the transfer of Private Placement Warrants to anyone who is not a permitted transferee would result in the Private Placement Warrants having substantially the same terms as the Public Warrants, the Company determined that the fair value of each Private Placement Warrant is equivalent to that of each Public Warrant. See Note 9 for further discussion of the pertinent terms of the Warrants and Note 10 for further discussion of the methodology used to determine the value of the Warrants. | Derivative Warrant Liability The Company accounts for the Warrants in accordance with the guidance contained in Accounting Standards Codification (“ASC”) 815, “Derivatives and Hedging”, under which the Warrants do not meet the criteria for equity treatment and must be recorded as liabilities.

See Note 9 for further discussion of the pertinent terms of the Warrants and Note 10 for further discussion of the methodology used to determine the value of the Warrants.
Class A Shares Subject to Possible Redemption | Class A Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Ordinary shares subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at March 31, 2022 and December 31, 2021, 23,000,000 Class A ordinary shares subject to possible redemption are presented as temporary equity outside of the shareholders’ deficit section of the Company’s condensed consolidated balance sheets. | Class A Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in ASC Topic 480, “Distinguishing Liabilities from Equity.” Ordinary shares subject to mandatory redemption is classified as a liability instrument and is measured at fair value.

Offering Costs | Offering Costs Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs are allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities are expensed as incurred and presented as non-operating expenses in the condensed consolidated statements of operations. Offering costs associated with the Class A ordinary shares are charged against their carrying value upon the completion of the Initial Public Offering. Deferred underwriting commissions are classified as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities. | Offering Costs Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the Initial Public Offering that were directly related to the Initial Public Offering.

Income Taxes | Income Taxes The Company accounts for income taxes under ASC Topic 740, “Income Taxes,” which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of March 31, 2022 or December 31, 2021, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals, or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented. The Company's management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. | Income Taxes The Company accounts for income taxes under ASC Topic 740, “Income Taxes,” which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return.

Net Income (Loss) Per Ordinary Share | Net Income (Loss) Per Ordinary Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A ordinary shares and Class B ordinary shares. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per ordinary share calculated by dividing the net income (loss) by the weighted average of ordinary shares outstanding for the respective period. ​ The calculation of diluted net income (loss) does not consider the effect of the warrants underlying the Units sold in the Initial Public Offering (including the consummation of the Over-allotment) and the private placement warrants to purchase an aggregate of 22,529,000 Class A ordinary shares in the calculation of diluted income (loss) per share, because the exercise of the warrants is contingent upon the occurrence of future events. As a result, diluted net income (loss) per share is the same as basic net income (loss) per share for the three months ended March 31, 2022 and 2021. Accretion associated with the redeemable Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value. A reconciliation of net income (loss) per ordinary share is as follows: ​

Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Corporation coverage limits of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. | Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Corporation coverage limits of $250,000.

Fair Value of Financial Instruments | Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the Company’s condensed consolidated balance sheets, primarily due to their short-term nature except for derivative warrant liabilities (see Note 10). The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities: Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active. Level 3: Unobservable inputs based on the Company's assessment of the assumptions that market participants would use in pricing the asset or liability. | Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the Company’s consolidated balance sheet, primarily due to their short-term nature.
