REVIEW RESPONSIBILITIES Primary - Structural Engineering Branch (SEB) Secondary - None I. AREAS OF REVIEW The following areas related to the seismic instrumentation program are reviewed: 1. Comparison with Regulatory Guide 1.12 A comparison of the proposed seismic instrumentation with the seismic instru- mentation guidelines of Regulatory Guide 1.12 (Ref. 4) is made. In addition, the bases for elements of the program that differ from Regulatory Guide 1.12 are reviewed. 2. Location and Description of Instrumentation The locations for the installation of seismic instrumentation such as tri- axial peak accelerographs, triaxial time history accelerographs, and triaxial response spectrum recorders that will be installed in selected Category I structures and components are reviewed. The bases for selection of the instrumentation and the locations and a discussion of the extent to which the seismic instrumentation will be employed to verify the seismic analyses following an earthquake are reviewed. 3. Control Room Operator Notification The procedures that will be followed to inform the control room operator of the peak acceleration level and the input response spectra values shortly after occurrence of an earthquake are reviewed. Also reviewed are the bases for establishing predetermined values for activating the readout of the seismic instrumentation to the control room operator. Rev. 1 - 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. These documents are made available to the public as part of the Commission's policy to inform the nuclear Industry and the general public of regulatory procedures and policies. Standard review plans are not substitutes for regulatory guides or the Commission s regulations and compliance with them is not required. The standard review plan sections are keyed to the
