tors to align such guidance with the definitions of small 
modular reactor and microreactor in section 7 of this Act. 
SEC. 5. FINANCIAL ASSISTANCE ELIGIBILITY FOR EFFI-
CIENT SMALL MODULAR REACTOR DEVELOP-
MENT, DEMONSTRATION, AND DEPLOYMENT. 
(a) IN GENERAL.—Notwithstanding any other provi-
sion of law, the Secretary of Energy, in providing any 
funding assistance to support the development, dem-
onstration, or deployment of grid-scale small modular re-
actors, shall not exclude from award eligibility projects or 
reactor technologies on the basis that a single reactor unit 
output exceeds any electrical megawatt threshold between 
50 and 500 electrical megawatts. 
(b) TREATMENT OF EXISTING PROGRAMS.—Nothing 
in this section shall be construed as limiting the authority 
of the Secretary of Energy to make awards within the ex-
plicit scope of Department of Energy solicitations issued 
prior to the date of enactment of this Act. 
SEC. 6. SMALL MODULAR REACTOR COMMERCIALIZATION 
AND INDUSTRIALIZATION COMPETITIVENESS 
WORKING GROUP. 
(a) IN GENERAL.—The Secretary of Energy shall es-
tablish a working group to be known as the ‘‘Small Mod-
ular Reactor Commercialization and Industrialization

Competitiveness Working Group’’ (in this section referred 
to as the ‘‘Working Group’’). 
(b) DUTIES.—The duties of the Working Group shall 
include the following: 
(1) To identify small modular reactor tech-
nologies the design for which an application has 
been submitted or received approval from the Nu-
clear Regulatory Commission, or a foreign nuclear 
regulator with a signed memorandum of cooperation 
with the Nuclear Regulatory Commission. 
(2) To assess, and recommend initiatives to im-
prove, the ability of the United States to— 
(A) serve as the preeminent geography to 
commercialize small modular reactor tech-
nologies after initial or first-of-a-kind deploy-
ment; and 
(B) secure and attract long-term manufac-
turing industrial base investment in small mod-
ular reactor fabrication. 
(3) To recommend policy changes that would 
improve the ability of the United States to host the 
manufacturing of small modular reactor technologies 
identified in paragraph (1) that are undergoing first- 
of-a-kind deployment outside of the United States.
