       Questions and Answers About the Transactions and the Extraordinary
General Meeting, page 11

   1.                                                   In this section, please
quantify the aggregate dollar amount and describe the nature of
                                                        what the sponsor and
its affiliates have at risk that depends on the completion of a
                                                        business combination.
Include the current value of securities held, loans extended, fees
                                                        due, and out-of-pocket
expenses for which the sponsor and its affiliates are awaiting
                                                        reimbursement. Provide
similar disclosure for the company's officers and directors, if
                                                        material. If, for
example, no loans are outstanding or expenses awaiting reimbursement,
                                                        state so directly.
   2.                                                   We note that certain
shareholders agreed to waive their redemption rights. Please describe
                                                        any consideration
provided in exchange for this agreement.

What are the transactions?, page 11

3.       Please revise to explain briefly the purpose of the transactions to
which you refer and the
         related agreements, such as the tax receivable agreement, as well as
the post-transaction
         ownership structure involving classes of stock and units that will be
outstanding.
Summary, page 25

4.       Please clarify if the sponsor and its affiliates can earn a positive
rate of return on their
         investment, even if other SPAC shareholders experience a negative rate
of return in the
         post-business combination company.
Risk Factors, page 43

5.       Please tell us whether the sponsor will receive additional securities
pursuant to an anti-
         dilution adjustment based on the company's additional financial
activities. To the extent
         they will, quantify the number and value of securities the sponsor
will receive. In
         addition, disclose the ownership percentages in the company before and
after the
         additional financing to highlight the dilution risk to public
stockholders.
6.       Disclose the material risks to unaffiliated investors presented by
taking the company
         public through a merger rather than an underwritten offering. These
risks could include
         the absence of due diligence conducted by an underwriter that would be
subject to liability
         for any material misstatements or omissions in a registration
statement
7.       Please revise the conflicts of interest discussion so that it
highlights all material interests
         in the transaction held by the sponsor and the company's officers and
directors. This
         could include fiduciary or contractual obligations to other entities
as well as any interest
         in, or affiliation with, the target company. In addition, please
clarify how the board
         considered those conflicts in negotiating and recommending the
business combination.
PIPE Investment, page 90

8.       Please describe the "certain commercial arrangements" to which you
agreed in exchange
         for the PIPE investment.
Certain NuScale LLC Projected Financial Information, page 99

9.       Please revise to disclose all material assumptions underlying the
projected financial
         information, the market assumed in developing those assumptions and
explain how those
         assumptions relate and resulted in the projections disclosed. Quantify
the underlying
         assumptions to the extent possible. Also, as applicable, explain how
the projected
         information currently disclosed is representative of your current
operations and
         opportunities, such as the "pipeline" referenced on page 183 and
anticipated delivery of
         modules beginning in 2027, as disclosed on page 182. Explain in detail
the reasons for
         any material difference.

10.      We note the term of the projections. Please explain the basis of the
projections beyond
         year three and if the forecasts reflect more than simple assumptions
about growth rates. It
         should be clear from your revisions how the projected growth rates are
sustainable over
         the selected period of time, and why assuming such growth rates are
reasonable.
11.      Refer to the first sentence of capitalized font on page 100 and revise
to clarify, if true, that
         you will not provide the update or revision except as required by law.

convert upon

partnerships and provide
         the material terms related to such agreements, including the duration
of the underlying
         agreements and the respective rights and obligations of the parties.

         partnerships are material, please revise to disclose the material

Exhibits

18.      We note your references to employment agreements on page 214. Please
file these
         agreements as exhibits to the registration statement. See Item
601(b)(10) of Regulation S-
         K.
General

19.      You note that the charter waived the corporate opportunities doctrine.
Please address this
         potential conflict of interest and whether it impacted your search for
an acquisition target.
20.      Please highlight the risk that the sponsor will benefit from the
completion of a business
         combination and may be incentivized to complete an acquisition of a
less favorable target
         company or on terms less favorable to shareholders rather than
liquidate.
21.      We note your disclosure on page 57 that the forum selection provision
does not apply to
         suits brought to enforce the Exchange Act. However, in Article IX of
the Bylaws, there is
         no mention of whether the forum provision applies to Exchange Act
claims. Please
         disclose whether the forum provision in your Bylaws applies to claims
arising under the
         Exchange Act and revise your proposed Bylaws accordingly.
22.      The discussion of the Tax Receivable Agreement (TRA) and the
redirection of cash flows
         to the continuing unitholders should be enhanced and given more
prominence in your
         prospectus. Please expand the discussion of the TRA as a principal
topic in the
         prospectus summary so that readers do not have to search for key
information about
         significant financial arrangements that will materially impact the
company's liquidity.
         Please ensure that your revised disclosure states clearly that you
expect the payments to be
         substantial and that the arrangement will reduce the cash provided by
the tax savings that
         would otherwise have been available to you for other uses. Because the
arrangement could
         be considered a windfall for the continuing unitholders, your
disclosure at the top of the
         prospectus should adequately address the fact that the agreement
confers significant
         economic benefits to the continuing unitholders and redirects cash
flows to them at the
         expense of the rest of your shareholders.
23.      Please disclose on your cover page and summary that you will be a
"controlled company"
         following the transactions and add appropriate risk factor disclosure
related to the
         corporate governance exemptions available to you and on which you
intend to rely.
24.      Please disclose the sponsor and its affiliates total potential
ownership in the combined
         company, assuming completion of the PIPE and exercise or conversion of
all securities.
25.      Revise your disclosure to show the potential impact of redemptions on
the per share value
         of the shares owned by non-redeeming shareholders by including a
sensitivity analysis
         showing a range of redemption scenarios, including minimum, maximum
and interim
         redemption levels.
26.      It appears that underwriting fees remain constant and are not adjusted
based on
 Christopher Sorrells

      redemptions. Revise your disclosure to disclose the effective
underwriting fee on a
      percentage basis for shares at each redemption level presented in your
sensitivity analysis
      related to dilution.
27.   Please revise to disclose all possible sources and extent of dilution
that shareholders who
      elect not to redeem their shares may experience in connection with the
business
      combination. Provide disclosure of the impact of each significant source
of dilution,
      including the amount of equity held by founders, convertible securities,
including warrants
      retained by redeeming shareholders, at each of the redemption levels
detailed in your
      sensitivity analysis, including any needed assumptions
28.   Quantify the value of warrants, based on recent trading prices, that may
be retained by
      redeeming stockholders assuming maximum redemptions and identify any
material
      resulting risks.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.

       Refer to Rules 460 and 461 regarding requests for acceleration. Please
allow adequate
time for us to review any amendment prior to the requested effective date of
the registration
statement.
