FINAL RULE - APPROVAL OF INCORPORATION BY REFERENCE OF AMERICAN SOCIETY OF MECHANICAL ENGINEERS CODE EDITIONS
The U.S. Nuclear Regulatory Commission (NRC) is amending its regulations to incorporate by reference the 2019 Edition of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code, Section III, Division 1, and Section XI, Division 1, and the 2020 Edition of the American Society of Mechanical Engineers Operation and Maintenance of Nuclear Power Plants, Division 1: OM Code: Section IST, for nuclear power plants. The NRC is also incorporating by reference the American Society of Mechanical Engineers OM Code Case OMN-28, âAlternative Valve Position Verification Approach to Satisfy ISTC-3700 for Valves Not Susceptible to Stem-Disk Separationâ; the 2011 Addenda to ASME NQAâ1â2008, âQuality Assurance Requirements for Nuclear Facility Applicationsâ (ASME NQAâ1bâ2011); and the 2012 and 2015 Editions of ASME NQAâ1, âQuality Assurance Requirements for Nuclear Facility Applications.â This action is in accordance with the NRCâs policy to periodically update the regulations to incorporate by reference new editions of the American Society of Mechanical Engineers Codes and is intended to maintain the safety of nuclear power plants and to make NRC activities more effective and efficient.
The final rule will decrease the burden for 10 CFR Part 50 from 3,641,926 hours and 42,218 responses to 3,636,646 hours and 42,196 responses, a reduction of 5,280 hours and 22 responses. This will result in an estimated reduction of 240 hours per response.
The final rule incorporates by reference OM and BPV Codes from ASME as described above, which reduces the burden on industry and the NRC by a reduction in alternative requests submitted and reviewed as a result of aspects of plant operation covered by these codes. A recent review of Code alternative requests submitted to the NRC over the last 5 year span found that submittals ranged from a few pages to several hundred pages, with an average of approximately 32 pages. However, the burden hours have been reduced as requests have become less complex to review over time. Therefore, the NRC estimates that a request requires an average of 150 hours of effort to develop the technical justification and an additional 80 hours to perform research, review, approve, process, and submit the document to the NRC for use of alternatives under 10 CFR 50.55a(z). Therefore, the total for estimated burden is 230 hours per request. In the same manner, the NRC estimates that the total burden to perform the technical review (including resolving technical issues), document the evaluation, and respond to the licenseeâs request is 115 hours per request.
Following the implementation phase, the industry will see a reduced burden for the aspects of plant operation covered by the codes in the final rule.
