Military use: that is clearly the reason for developing Small Nuclear Reactors

If the testing goes well, a commercially developed, Nuclear Regulatory Commission licensed reactor will be demonstrated on a “permanent domestic military installation.
Pentagon awards contracts to design mobile nuclear reactor Defense News 
By: Aaron Mehta    March 9  WASHINGTON— The Pentagon on Monday issued three contracts to start design work on mobile, small nuclear reactors, as part of a two-step plan towards achieving nuclear power for American forces at home and abroad.

The department awarded contracts to BWX Technologies, Inc. of Virginia, for $13.5 million; Westinghouse Government Services of Washington, D.C. for $11.9 million; and X-energy, LLC of Maryland, for $14.3 million, to begin a two-year engineering design competition for a small nuclear microreactor designed to potentially be forward deployed with forces outside the continental United States.

The combined $39.7 million in contracts are from “Project Pele,” a project run through the Strategic Capabilities Office (SCO), located within the department’s research and engineering side. The prototype is looking at a 1-5 megawatt (MWe) power range. The Department of Energy has been supporting the project at its Idaho National Laboratory.

Pele “involves the development of a safe, mobile and advanced nuclear microreactor to support a variety of Department of Defense missions such as generating power for remote operating bases,” said Lt. Col. Robert Carver, a department spokesman. “After a two-year design-maturation period, one of the companies funded to begin design work may be selected to build and demonstrate a prototype.”…….

A second effort is being run through the office of the undersecretary of acquisition and sustainment. That effort, ordered in the 2019 National Defense Authorization Act, involves a pilot program aiming to demonstrate the efficacy of a small nuclear reactor, in the 2-10 MWe range, with initial testing at a Department of Energy site in roughly the 2023 timeframe.

If the testing goes well, a commercially developed, Nuclear Regulatory Commission licensed reactor will be demonstrated on a “permanent domestic military installation by 2027,” according to DoD spokesman Lt. Col. Mike Andrews. “If the full demonstration proves to be a cost effective energy resilience alternative, NRC-licensed [reactors] will provide an additional option for generating power provided to DoD through power purchase agreements.”…….

According to Dr. Jonathan Cobb, a spokesman for the World Nuclear Association, small nuclear reactors come in three flavors. The first, small modular reactors, sit in the 20-300 MWe range and are approaching the point they will appear on market.

The second category sits from 10-100 megawatts, and have been used in transports such as icebreakers. According to Cobb, a pair of 32 MWe reactors, based on icebreaker technology, are being used aboard the Akademik Lomonosov, a Russian “floating power plant.”

The third category, covering what the Pentagon appears most interested in, is a category known as microreactors. The challenge, Cobb said, is that this group is the furthest behind technologically, with demonstrations of commercial systems targeted for “the second half of the 2020s,” putting them in the “ballpark” of what DoD is looking for with its A&S effort……

Edwin Lyman, director of the Nuclear Safety Project at the Union of Concerned Scientists, has concerns about the availability of fuel to power a proliferation of small nuclear reactors. He noted, “there are no clear plans for manufacturing the quantity of high-assay low enriched uranium, much less the production of high-quality TRISO [TRi-structural ISOtropic particle] fuel, that would be able to meet timelines this decade.”……

Lord, for her part, would not rule out working with foreign allies on the nuclear program in some way, saying “We always talk with our partners and allies about collaboration. We have many umbrella vehicles, if you will, to do that, particularly with [National Technology and Industrial Base] countries — U.K., Canada, Australia. We have a little bit of an easy button there for working back and forth with technical information.”…    https://www.defensenews.com/smr/nuclear-arsenal/2020/03/09/pentagon-to-award-mobile-nuclear-reactor-contracts-this-week/?fbclid=IwAR2MTkRUDqIkruQHY0RivblBzoSY6gubpl8gkWDUDhedVwZEGstJhHYLb6U#.XmawxEl-aJ0.facebook
