Summary

Requires the Secretary to send a report to Congress within 180 days after November 15, 2021 explaining how micro-reactors and small modular reactors could make energy more reliable and cut carbon emissions. The report must go to the Senate Committee on Energy and Natural Resources and the House Committees on Energy and Commerce and on Science, Space, and Technology. Defines a few key terms in one line each: advanced nuclear reactor (see another law), isolated community (see another law), micro-reactor (an advanced reactor that makes no more than 50 megawatts), National Laboratory (see another law), and small modular reactor (an advanced reactor under 300 electrical megawatts that can be built with similar reactors at one site). The report must check whether current rules for Department facilities need changes to ensure at least 3 days of backup power during grid failures, protection from cyberattacks and electromagnetic pulses, and resilience to extreme natural events (for example, earthquakes, storms, floods, and extreme temperatures). It must include a plan for using nuclear energy to meet resilience and carbon goals, a plan to work with private industry to deploy these reactors to remote communities to replace diesel and other fossil fuels, an assessment of the value of switching facilities to these reactors or co-located nuclear power during outages, and plans to deploy a micro-reactor and a small modular reactor for a Department facility in the United States by 2026 and a small modular reactor by 2029, plus to include these reactors in future facility planning. The Secretary must also offer financial and technical help for feasibility studies to find sites in isolated communities, do strong community outreach before funding projects, and not give more than 50 percent of the available assistance funds to National Laboratories.

(a)Definitions
In this section: (1) Advanced nuclear reactor (2) Isolated community
(3)Micro-reactor (4) National Laboratory
The term “micro-reactor” means an advanced nuclear reactor that has an electric power production capacity that is not greater than 50 megawatts.
(5)Small modular reactor
The term “small modular reactor” means an advanced nuclear reactor— (A)
(B)that can be constructed and operated in combination with similar reactors at a single site.
(b)Report
Not later than 180 days after November 15, 2021, the Secretary shall submit to the Committee on Energy and Natural Resources of the Senate and the Committees on Energy and Commerce and Science, Space, and Technology of the House of Representatives a report that describes how the Department could enhance energy resilience and reduce carbon emissions with the use of micro-reactors and small modular reactors.
(c)Elements
The report required by subsection (b) shall address the following:
(1)An evaluation by the Department of current resilience and carbon reduction requirements for energy for facilities of the Department to determine whether changes are needed to address—
(A)the need to provide uninterrupted power to facilities of the Department for at least 3 days during power grid failures;
(B)the need for protection against cyber threats and electromagnetic pulses; and
(C)resilience to extreme natural events, including earthquakes, volcanic activity, tornados, hurricanes, floods, tsunamis, lahars, landslides, seiches, a large quantity of snowfall, and very low or high temperatures.
(2)A strategy of the Department for using nuclear energy to meet resilience and carbon reduction goals of facilities of the Department.
(3)A strategy to partner with private industry to develop and deploy micro-reactors and small modular reactors to remote communities in order to replace diesel generation and other fossil fuels.
(4)An assessment by the Department of the value associated with enhancing the resilience of a facility of the Department by transitioning to power from micro-reactors and small modular reactors and to co-located nuclear facilities with the capability to provide dedicated power to the facility of the Department during a grid outage or failure.
(5)The plans of the Department—
(A)for deploying a micro-reactor and a small modular reactor to produce energy for use by a facility of the Department in the United States by 2026;
(B)for deploying a small modular reactor to produce energy for use by a facility of the Department in the United States by 2029; and
(C)to include micro-reactors and small modular reactors in the planning for meeting future facility energy needs.
(d)Financial and technical assistance for siting micro-reactors, small modular reactors, and advanced nuclear reactors
(1)In general
The Secretary shall offer financial and technical assistance to entities to conduct feasibility studies for the purpose of identifying suitable locations for the deployment of micro-reactors, small modular reactors, and advanced nuclear reactors in isolated communities.
(2)Requirement
Prior to providing financial and technical assistance under paragraph (1), the Secretary shall conduct robust community engagement and outreach for the purpose of identifying levels of interest in isolated communities.
(3)Limitation
The Secretary shall not disburse more than 50 percent of the amounts available for financial assistance under this subsection to the National Laboratories.
