In pursuing that goal, we have always tried to include…, When we think about frontline or essential workers during the Covid-19 pandemic, we often think of doctors, nurses, grocery clerks, bus drivers, and others who perform critical services and can’t work from home. The total number of people who died in the earthquake and the tsunami that it generated is still being assessed, but the official estimation already exceeds 14,000.1 The natural disaster also caused substantial damage to the Fukushima Daiichi nuclear power plant, the consequences of which are still unclear. By order dated May 20, 2016, the NRC approved the direct transfer of Possession Only License No. This document has been published in the Federal Register. The outer concrete building is the "secondary" containment and is smaller and less robust (and thus cheaper to build) than the containment buildings used at most reactors. documents in the last year, by the National Highway Traffic Safety Administration Register documents. Seen from the most basic level, nuclear reactors are just a fancy way of boiling water. A lateral shift along circumferential cracks at the welds by as little as 1/8 inch can result in the misalignment of the fuel and the inability to insert the control rods coupled with loss of fuel core cooling capability.

If you are using public inspection listings for legal research, you Only official editions of the In a typical design concept of a commercial BWR, the following process occurs: The core inside the reactor vessel creates heat. [FR Doc. documents in the last year, 38 It is further ordered that, consistent with 10 CFR 2.1315(b), the license amendment that makes changes, as indicated in Enclosure 2 to the cover letter forwarding this Order, to conform the license to reflect the subject direct license transfer is approved. on Document page views are updated periodically throughout the day and are cumulative counts for this document. The BWR is a power reactor; that is, it is designed to generate electrical power. the material on FederalRegister.gov is accurately displayed, consistent with Paul Gunter, NIRS, March, 1996, updated by Michael Mariotte, NIRS, March 2011, For Immediate Release–Contact Diane D’Arrigo, Radioactive Waste Project Director Nuclear Information and Resource Service dianed@nirs.org; 202-841-8588 Audio teleconference on VLLW: https://www.nirs.org/wp-content/uploads/2020/07/Telebrief_VLLW-landfills_2020-07-15.mp3   October 21, 2020 Nearly 10,000 comments were submitted by today’s deadline to the US Nuclear Regulatory Commission (NRC) against its plan to deliberately allow nuclear waste, mainly from nuclear power reactors, to go to…, For immediate release: Contacts: Tim Judson, NIRS, 301-270-6477 Paul Gunter, Beyond Nuclear, 301-523-0201 David Kraft, NEIS, 773-342-7650 Nuclear power plants appear to be sites of COVID-19 super-spreader events, but government regulators are ignoring the problem. The core shroud is a large stainless steel cylinder of circumferentially welded plates surrounding the reactor fuel core. A German utility operating a GE BWR where extensive core shroud cracking was identified estimated the cost of replacement at $65 million dollars. Until the ACFR grants it official status, the XML Dated at Rockville, Maryland this 24th day of September 2019. on The Public Inspection page may also Miles O'Brien and David Brenner of Columbia University's Center for … • BWRs require more complex calculations for managing consumption of nuclear fuel during operation due to "two phase (water and steam) fluid flow" in the upper part of the core. DPR-45 on August 28, 1973. Boiling water reactor – BWR A boiling water reactor (BWR) is cooled and moderated by water. offers a preview of documents scheduled to appear in the next day's informational resource until the Administrative Committee of the Federal For example, 23 of these BWRs use a smaller GE Mark I pressure suppression containment conceived as a cost-saving alternative to the larger reinforced concrete containments marketed by competitors. Accordingly, pursuant to Sections 161b, 161i, and 184 of the Act, 42 U.S.C. electronic version on GPO’s govinfo.gov. In order to protect the Mark I containment from a total rupture it was determined necessary to vent any high pressure buildup. It is further ordered that, after receipt of all required regulatory approvals of the proposed direct license transfer, DPC shall inform the Director of NMSS in writing of such receipt, and of the date of closing of the transfer, no later than 2 business days prior to the date of closing of the direct license transfer. Notice of the application was published in the Federal Register on October 11, 2018 (83 FR 51509). LACBWR permanently ceased operations on April 30, 1987. It takes place at a lower pressure as in PWR, what allows the water to boil inside the pressure vessel producing the steam that runs the turbines. LS currently maintains a lease for the above-ground LACBWR structures (other than the LACBWR ISFSI) and previously assumed responsibility for all NRC-licensed activities at the LACBWR site, including responsibility under the license to complete decommissioning. The purpose of a reactor containment system is to create a barrier against the release of radioactivity generated during nuclear power operations from certain "design basis" accidents, such as increased pressure from a single pipe break. 12/28/2020, 145 The atmosphere of the drywell is connected through large diameter pipes to a large hollow doughnut-shaped pressure suppression pool called "the torus", or wetwell, which is half-filled with water. About the Federal Register The findings set forth above are supported by an NRC safety evaluation dated September 24, 2019, which is available at ADAMS Accession No. 12/28/2020, 386 are not part of the published document itself. These tools are designed to help you understand the official document The amendment shall be issued and made effective at the time the proposed direct license transfer is completed. In 1986, Harold Denton, then the NRC’s top safety official, told an industry trade group that the "Mark I containment, especially being smaller with lower design pressure, in spite of the suppression pool, if you look at the WASH 1400 safety study, you’ll find something like a 90% probability of that containment failing." LACBWR is located on the east bank of the Mississippi River in Vernon County, Wisconsin, about 1 mile south of the Village of Genoa, Wisconsin, and approximately 19 miles south of the city of La Crosse, Wisconsin, and is co-located with the Genoa Generating Station (Genoa 3), which is a coal-fired power plant that is still in operation.
