Advanced Nuclear Reactor Plant Parameter Envelope and Guidance Advanced Nuclear Reactor Plant Parameter Envelope and Guidance BK McDowell D Goodman NRIC-21-ENG-0001; PNNL-30992 | 2.18.2021 Advanced Nuclear Reactor Plant Parameter Envelope and Guidance Summary Pacific Northwest National Laboratory (PNNL) is supporting the National Reactor Innovation Center (NRIC) at Idaho National Laboratory (INL) by developing advanced nuclear reactor plant parameter envelopes (PPEs) to facilitate environmental reviews of potential future advanced reactor demonstration projects at INL and elsewhere in the United States. Two PPEs are developed in this report for two size ranges: (1) microreactors, which are defined for this PPE as single units with outputs of 60 MWt or less, and (2) small- to medium-sized advanced reactors with outputs above 60 MWt up to 1,000 MWt. This report describes the methodology for developing the PPEs, including reactor vendor responses to NRIC questionnaires, input from INL staff, independent assessments by subject matter experts, and a review of regulatory requirements a vendor would have to meet during construction and operation. This report presents the compiled PPEs for surrogate plants derived from these inputs, lists documentation supporting the PPE, and provides recommendations for its use when developing an environmental impact assessment.

  • VTR EIS) (DOE/EIS-0542) Comment Submittal by Tami Thatcher, February 11, 2021
    Public Comment Submittal on the U.S. Department of Energy’s Versatile Test Reactor Draft Environmental Impact Statement (VTR EIS) (DOE/EIS-0542) Comment submittal by Tami Thatcher, February 11, 2021. Comments Due: February 16, 2021. Sent by email to [email protected] BACKGROUND The draft Environmental Impact Statement for the Versatile Test Reactor (VTR) considers the potential environmental impacts for the construction and operation a new Department of Energy regulated test reactor, and associated facilities for post-irradiation evaluation of fuels and other materials, VTR driver fuel production (fuel feedstock and fuel fabrication), and the managing of its spent nuclear fuel. The VTR would be a 300 megawatt (thermal) fast neutron reactor that does not generate electricity and is only used for high neutron bombardment of fuels and other materials. The VTR is a pool-type, sodium-cooled reactor with a fast-neutron spectrum and will use a uranium-plutonium-zirconium metal fuel. GE Hitachi Nuclear Energy is working with the Idaho National Laboratory on the VTR conceptual design based on its PRISM reactor, which was based on the Experimental Breeder II reactor. 1 The EBR II which was operated by Argonne National Laboratory – West at the Idaho site which is now the Materials and Fuels Complex (MFC) at the INL, although the EBR II has been dismantled. The 60-year-old pyroprocessing facility at MFC, the Fuel Conditioning Facility (FCF) remains at the former EBR II complex. SUMMARY OF VTR EIS INADEQUACY I disapprove of the DOE’s preferred alternative, to construct the VTR at either proposed location, the Idaho National Laboratory or the Oak Ridge National Laboratory because of cost, accident risk and nuclear weapons proliferation concerns.

  • UCS Technical Rebuttal to the Idaho National Laboratory's Opinions on the Versatile (Fast) Test Reactor Edwin Lyman Senior Sc
    UCS technical rebuttal to the Idaho National Laboratory’s opinions on the Versatile (Fast) Test Reactor Edwin Lyman Senior Scientist, Global Security Program, Union of Concerned Scientists June 11, 2018 On February 15, I published a blog post entitled “The Versatile Fast Neutron Source: A Misguided Nuclear Reactor Project.” The post was critical of the recent Congressional efforts to compel the Department of Energy (DOE) to build a multibillion-dollar fast-neutron nuclear reactor without thorough evaluation of the need for such a project and its cost and benefits. In response, on March 13, the Idaho National Laboratory (INL) released an unsigned “technical rebuttal” responding to what it characterized as “personal opinions that are inaccurate or misleading.” It starts by arguing that such a reactor is needed, and then comments on seven statements from my blog post. Given that INL would likely be the site for such a reactor and therefore has a vested interest in the project, the lab’s favorable opinions on its merits come as no surprise. However, INL’s response contains numerous inaccurate or misleading statements. Below, I list the seven quotes from my blog post, and respond to INL’s rebuttal. 1. “What may not be clear from the name is that this facility itself would be an experimental fast reactor, likely fueled with weapon-usable plutonium.” a) “Experimental fast reactor” versus “test reactor” INL takes issue with my description of the reactor under question as an “experimental fast reactor” and insists it should be called a “test reactor.” In fact, other than a legal distinction, calling it a “test reactor” would make no meaningful difference.

  • How DOE and Industry Collaborations Are Paving the Way for Advanced Nuclear Reactors
    As seen in the April 2021 issue of NuclearNews Copyright © 2021 by the American Nuclear Society April 2021 Road to Advanced Nuclear How DOE and industry collaborations are paving the way for advanced nuclear reactors 24 Nuclear News April 2021 By Cory Hatch s electric utilities rush to reduce carbon emissions by investing in intermittent renew- ables such as wind and solar, they often rely heavily on fossil fuels to provide steady A baseload power. More than 60 percent of the nation’s electricity is still generated with fossil fuels, especially coal- fired and gas- fired power plants that have the ability to quickly ramp up or ramp down power to follow loads on the electric grid. Most experts agree that even with a radical advancement in energy storage technology, relying exclusively on wind and solar to replace fossil fuels won’t be enough to maintain a stable electric grid and avoid the major impacts of climate change. To complete the transition to a carbon- free energy future, one key piece of the puzzle remains: nuclear power. Conventional light water reactors already account for roughly 55 percent of all carbon- free electric- ity produced in the United States. A crucial distinction between nuclear and other clean sources like wind and solar is that nuclear remains one of the few ways to generate reliable, carbon- free power 24 hours a day, 365 days a year. But conventional LWRs have three major limitations. First and foremost is cost. U.S. utilities that have attempted new reactor construction in the past decade or so have faced major cost overruns and construction delays.

  • Us Nuclear Industry Council (Usnic)
    U.S. NUCLEAR INDUSTRY COUNCIL (USNIC) Advanced Nuclear Reactor Development Benefits from Versatile Test Reactor U.S. Nuclear Industry Council Policy Brief 24 January 2020 Findings To maintain U.S. global advanced nuclear leadership, it is important to have a versatile, high- energy neutron source. The U.S. Versatile Test Reactor (VTR) can provide that capability to accelerate research and test nuclear materials, fuel, and other components. The VTR can assist in developing innovative nuclear energy technologies that have inherent safety features, lower waste yields, the capability to consume waste materials, the ability to support both electric and non-electric applications, and other improvements over the current generation of reactors. Furthermore, the success of the VTR will advance the U.S. industry by not having domestic nuclear developers relying upon Russian or Chinese test facilities and allowing the U.S. to be a competitive international resource for irradiation and testing services. In addition, constructing the VTR will enable the U.S. government to demonstrate advanced reactor technologies. The U.S. Nuclear Industry Council (USNIC), supports fully funding the U.S. Department of Energy’s (DOE) appropriations requests to ultimately construct and operate the VTR. Inconsistent or inadequate funding will only increase the uncertainty of the schedule, resulting in cost increases and potentially project failure. DOE should continue developing the conceptual design, preparing the Environmental Impact Statement (EIS), establishing processes and procedures to construct the facility on-time and within budget, and pursuing creative domestic and international co-financing opportunities. Background The demand for next-generation nuclear power is expected to grow as the world expands energy production from clean, zero emitting sources.

    Advanced Nuclear Reactors: Technology Overview and Current Issues April 18, 2019 Congressional Research Service https://crsreports.congress.gov R45706 SUMMARY R45706 Advanced Nuclear Reactors: Technology April 18, 2019 Overview and Current Issues Danielle A. Arostegui All nuclear power in the United States is generated by light water reactors (LWRs), which were Research Assistant commercialized in the 1950s and early 1960s and are now used throughout most of the world. LWRs are cooled by ordinary (“light”) water, which also slows (“moderates”) the neutrons that Mark Holt maintain the nuclear fission chain reaction. High construction costs of large conventional LWRs, Specialist in Energy Policy concerns about safety raised by the 2011 Fukushima nuclear disaster in Japan, and other issues have led to increased interest in unconventional, or “advanced,” nuclear technologies that could be less expensive and safer than existing LWRs. An “advanced nuclear reactor” is defined in legislation enacted in 2018 as “a nuclear fission reactor with significant improvements over the most recent generation of nuclear fission reactors” or a reactor using nuclear fusion (P.L. 115-248). Such reactors include LWR designs that are far smaller than existing reactors, as well as concepts that would use different moderators, coolants, and types of fuel. Many of these advanced designs are considered to be small modular reactors (SMRs), which the Department of Energy (DOE) defines as reactors with electric generating capacity of 300 megawatts and below, in contrast
