-qsso UNITED STATES NUCLEAR REGULATORY COMMISSION ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D.C. 20555-0001 November 17, 2003 Dr. William D. Travers Executive Director for Operations U. S. Nuclear Regulatory Commission Washington, DC 20555-0001
SUBJECT:
DRAFT FINAL REVISION 3 OF REGULATORY GUIDE 1.32, "CRITERIA FOR POWER SYSTEMS FOR NUCLEAR POWER PLANTS"
Dear Dr. Travers:
During the 507`' meeting of the Advisory Committee on Reactor Safeguards, November 5-7, 2003, we met with representatives of the NRC staff to discuss the draft final Revision 3 of Regulatory Guide 1.32, "Criteria for Power Systems for Nuclear Power Plants." We also had the benefit of the documents referenced.
RECOMMENDATION Revision 3 of Regulatory Guide 1.32 should be issued.
DISCUSSION Revision 3 of Regulatory Guide 1.32 addresses an acceptable method for licensees to satisfy Criteria 17 and 18 of 10 CFR Part 50, Appendix A when designing, modifying, operating, testing, and documenting Class 1 E power systems for nuclear power plants. This Guide endorses Institute of Electrical and Electronics Engineers (IEEE) Standard 308-2001, "Criteria for Class 1 E Power Systems for Nuclear Power Generating Stations," with one exception. IEEE 308-2001 states that shared Class 1 E (safety-related) power systems are permissible in multi-unit stations provided certain rigorous conditions for sharing are met. The staff took exception to sharing dc power systems because Regulatory Guide 1.81, "Shared Emergency and Shutdown Electric Systems for Multi-Unit Nuclear Power Plants," states that dc power systems in multi-unit nuclear power plants should not be shared. We agree with the staff's exception to IEEE Standard 308-2001.
Proposed Revision 3 of Regulatory Guide 1.32 was issued for public comment in May 2003 as Draft Regulatory Guide DG-1 079. One comment was received and resolved satisfactorily by the staff. Revision 3 of Regulatory Guide 1.32 should be issued.
Sincerely, Mario V. Bonaca ACRS Chairman EDO -- G20030710
