cific guidelines: A. Regulatory Guide 1.160, as related to the effectiveness of maintenance activities for onsite emergency ac power sources including grid-risk-sensitive maintenance activities (i.e., activities that tend to increase the likelihood of a plant trip, increase LOOP frequency, or reduce the capability to cope with a LOOP or SBO). 8.2-9 Revision 4 - March 2007 B. Regulatory Guide 1.182, as related to implementing the provisions of 10 CFR 50.65 (a)(4) by endorsing Section 11 to NUMARC 93-01, “Nuclear Energy Institute Industry Guideline for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants, February 22, 2000. Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. Compliance with GDC 2 requires that nuclear power plant structures, systems, and components important to safety be designed to withstand the effects of natural phenomena such as high and low atmospheric temperatures, high wind, rain, lightning discharges, ice and snow conditions,and weather events causing regional effects without loss of capability to perform their intended safety function. With regard to the offsite power system, this criterion requires that capability for the offsite power system to perform its functions be retained during the most severe natural phenomena that have been historically reported for the site and surrounding area. Therefore, the offsite power system and its components must normally be located in areas that provide protection from the effects of high and low atmospheric temperatures, high wind, rain, lightning discharges, ice and snow conditions,and weather events causing regional effects Meeting this requirement provides assurance that equipment and structures are designed to withstand the effects associated with natural phenomena, thus decreasing the probability that climatology-related natural phenomena could
