.166, "Pre-Earthquake Planning and Immediate Nuclear Power Plant Operator Post-Earthquake Actions." 5. Electric Power Research Institute, "A Criterion for Determining Exceedance of the Operating Basis Earthquake," EPRI NP-5930, Palo Alto, California, July 1988. 6. Regulatory Guide 8.8 “Information Relevant To Ensuring That Occupational Radiation Exposures At Nuclear Power Stations Will Be As Low As Is Reasonably Achievable.” 3.7.4-9 Draft Revision 3 - August 2013 SRP Section 3.7.4 Description of Changes Section 3.7.4 “SEISMIC INSTRUMENTATION” This SRP section affirms the technical accuracy and adequacy of the guidance previously provided in Revision 2, dated March 2007 of this SRP. See ADAMS Accession No. ML070460349. Changes include considerations in areas related to seismic instrumentation based on lessons learned from past 3.7.4 reviews. Each section of the SRP has text that was updated for editorial and clarifying purposes. The technical changes incorporated in Revision 3, dated May 2013: Secondary reviewers added for the purpose of the review of radiation protection regarding the ALARA review. II. ACCEPTANCE CRITERIA 1. Clarified the criteria for digital seismic instrumentation and where the instruments should be located. 2. Clarified that a transfer function is needed between elevation of the definition of the operating basis earthquake (OBE) and the location of the seismic instrumentation. 3. 10 CFR 20.1101(b) was added regarding the ALARA review. III. REVIEW PROCEDURES 1. Clarified that suitable seismic instrumentation promptly evaluates the seismic response of safety-related or risk significant plant features after an earthquake. 2. Clarified the review of ALARA. VI. REFERENCES Added Regulatory Guide 8.8.
