NRC-HQ-60-17-T-0002 . In the past, breeder-reactor development focused on reactors with low breeding ratios, from 1.01 for the Shippingport Reactor running on thorium fuel and cooled by conventional light water to over 1.2 for the Soviet BN-350 liquid-metal-cooled reactor. TWFN Auditorium . Engineering Mechanics Corporation of Columbus, OH Power reactors Light-water reactors PWRs and BWRs. All standards and guidelines developed over the last 60 years in the commercial nuclear power business are based on Zr/UO 2. Because of these two facts, light water reactors have a relatively small moderator volume and therefore have compact cores. 1 1) Purpose The U.S. Nuclear Regulatory Commission (NRC) has a variety of options for performing … Issuance of this RG does not constitute backfitting as defined in 10 CFR 50.109 (referred to as the Backfit Rule) and is not otherwise inconsistent … Accession Number: ML19241A336. There are two basic types: the pressurized-water reactor (PWR) and the boiling-water reactor (BWR). This important milestone paves the way for future deployment, additional applications, and allows for years of preparatory work by the NRC to be put into practice. MARCH 2019. Small Nuclear Power Reactors (Updated May 2020) ... (NRC) has released a draft white paper on its strategy for reviewing licensing applications for advanced non-light water reactor technologies. Package Contents. ADVANCED NON-LIGHT-WATER REACTORS MATERIALS AND OPERATIONAL EXPERIENCE . Clean Air Task Force (CATF) welcomes the submission by Oklo of the first ever non-light water reactor combined operating license application (COLA) to the Nuclear Regulatory Commission (NRC).

Light-water reactors (LWRs) are power reactors that are cooled and moderated with ordinary water. The focus is on regulatory policy and licensing issues that have arisen in the past so that NRC staff will be in a better position to deal with these matters in the future. 8:45 AM . The reactor is cooled with heavy or light water, fueled with natural uranium dioxide pellets.
PREPARED BY: NUMARK Associates, Inc. R. Turk, D. Haas, W. von Lensa . This report describes the U.S. Nuclear Regulatory Commission’s (NRC’s) history with the licensing of non-light water reactors (LWRs). 8:30 AM Opening Remarks Ray Furstenau, Director, Office of Nuclear Regulatory Research . The following links on this page are to Adobe Portable Document Format (PDF) files. NRC staff has developed the "Non-Light Water Reactor Review Strategy Staff White Paper," dated September 2019, to provide internal guidance for the review of non-LWR applications in the near-term. December 9-11, 2019 .

A Regulatory Review Roadmap For Non-Light Water Reactors Research & Development Conceptual Design Preliminary Design Final Design Regulatory Approval Advanced Reactors Policy Branch Division of Safety Systems, Risk Assessment, and Advanced Reactors Office of New Reactors December 2017 . Until a few years ago, very few considered the possibility of using fuel systems in light water reactor that were not based on a zirconium alloy and uranium dioxide (UO 2).

Rockville, MD . One next generation design, the supercritical water reactor, is even less moderated.
