December 9-11, 2019 . Package Contents. The reactor is cooled with heavy or light water, fueled with natural uranium dioxide pellets. Because of these two facts, light water reactors have a relatively small moderator volume and therefore have compact cores. 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 .

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. Power reactors Light-water reactors PWRs and BWRs. Program at a Glance . Advanced Non-Light Water Reactors – Materials and Component Integrity Workshop .

Rockville, MD . The heat from the reaction is used to produce … The NRC said it expects to finalise the draft paper by November, with submission of the first non-LWR application expected by December 2019. There are two basic types: the pressurized-water reactor (PWR) and the boiling-water reactor (BWR). 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). 8:30 AM Opening Remarks Ray Furstenau, Director, Office of Nuclear Regulatory Research . Date Released: Thursday, August 29, 2019. 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. 1 1) Purpose The U.S. Nuclear Regulatory Commission (NRC) has a variety of options for performing … 8:45 AM . One next generation design, the supercritical water reactor, is even less moderated.

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. Accession Number: ML19241A336. 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.

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). U.S. Nuclear Regulatory Commission . ADVANCED NON-LIGHT-WATER REACTORS MATERIALS AND OPERATIONAL EXPERIENCE . CONTRACT NO. Light-water reactors (LWRs) are power reactors that are cooled and moderated with ordinary water. Past Non-Light Water Reactor Activities and Pre-application Safety Evaluation Reports In the … The following table provides reference to ARCAP-related activities that have been provided to date. The deuterated water increases the neutron lifetime in comparison with a light water reactor. 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 … PREPARED BY: NUMARK Associates, Inc. R. Turk, D. Haas, W. von Lensa . NEI 18-04 Rev 1 Risk-Informed Performance-Based Technology Guidance for Non-Light Water Reactors. 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. MARCH 2019. This report describes the U.S. Nuclear Regulatory Commission’s (NRC’s) history with the licensing of non-light water reactors (LWRs). All standards and guidelines developed over the last 60 years in the commercial nuclear power business are based on Zr/UO 2. Monday, December 9th, 2019 . NRC-HQ-25-14-E-0004 TASK ORDER NO. The non-light water reactor design criteria in RG 1.232 provides guidance intended to support the development of the PDC. TWFN Auditorium .
