AREAS OF REVIEW The hydrometeorologic design basis is developed in this section of the safety anal- ysis report (SAR) to assure that safety-related facilities and water supply are not affected by ice flooding or blockage. The areas of review include: 1. The regional history and types of historical ice accumulations (i.e., ice jams, wind-driven ice ridges, floes, etc.). 2. The potential for ice-produced forces on, or blockage of, safety-related facilities. 3. The potential effects of ice-induced high or low flow levels on safety-related facilities and water supplies. If there is evidence of potential structural effects, the Structural Engineering Branch (SEB) will be requested by HGEB to ascertain whether these effects are prop- erly considered in the structural design basis for the plant; similarly, if there is evidence of potential mechanical effects, the Mechanical Engineering Branch (MEB) and the Auxiliary Systems Branch (ASB) will be requested by HGEB to ascertain whether these effects are properly considered in the mechanical design basis for the plant. The staff will develop a position based on the analysis; resolve, if possible, differences between the applicant's and staff's estimates of ice effects; and write the SER input accordingly. II. ACCEPTANCE CRITERIA Acceptance criteria for this SRP section are based on meeting the requirements of the following regulations: 1. 10 CFR Part 50, §50.55a as it requires structures, systems, and components to be designed and constructed to quality standards commensurate with the impor- tance of the safety function to be performed. Rev. 2 - July 1981 USNRC STANDARD REVIEW PLAN Standard review plans are prepared for the guidance of the Office of Nuclear Reactor Regulation staff responsible for the review of applications to construct and operate nuclear power plants.
