Licensee Action on Previous Enforcement Matters (Open)
Deviation 269/86-20-02, Discrepancies Between FSAR and Installed Seismic Instrumentatio Section 3.7.4.1 of the Oconee Final Safety Analysis Report (FSAR)
provides the location and description of the seismic instrumentation installed at the sit The FSAR describes six locations, all in the Unit 1 plant, where peak recording accelerometers are to be installe Contrary to the above FSAR requirements, only one peak recording accelerometer was operabl During this inspection, the inspector reviewed FSAR requirements for seismic monitoring, visually examined seismic instrumentation, reviewed procedures addressing inspection and calibration of seismic instrumenta tion and reviewed records of inspections made on seismic instrumentatio Examination of equipment showed that there are three different systems that provide separate indications of seismic event These are a SMA-3 strong motion acceleration system, TS-3A seismic Trigger Switch and six 2G peak recording accelerometer The SMA-3 strong motion acceleration system is a multichannel, centralized recording, magnetic tape accelerograph designed to detect and record strong local earthquakes. The system consists of a seismic trigger, two force balance accelerometers and a
recorde The force balance accelerometers are located in the Unit 1 tendon gallery and reactor building. The recorder is located in the Unit 1 cable room. The seismic trigger is located in the Unit 1 tendon gallery. The operational sequence is as follows: the seismic trigger senses the initial earthquake ground motion with a normal setting of 0.01g and actuates the SMA-3 to full operation in less than 0.1 seconds. The SMA-3 operates for as long as the trigger detects the earthquake plus an additional 110 second The accelerograph can thus record a single earthquake or a sequence of earthquakes and aftershocks lasting as long as 30 minute The TS-3A triaxial seismic trigger switch located in the tendon gallery with an accelerometer feeds an alarm to the control room when a seismic earth motion of 0.05g (Design Base Earthquake) is encountere If the design earthquake is exceeded, Units 1, 2 and 3 are to be shut dow The 2G peak recording accelerometers are self contained devices requiring no external powe The device senses and records peak acceleration triaxially. The recording is scratched permanently on a metal plate which is both serialized and keyed to the recorde There is one 2G peak recording accelerometer in the Unit 1 tendon gallery and five 2G peak recording accelerometers located at various locations in the reactor building. Deviation 269/86-20-02 was generated because five of these instruments were out of servic Two. of the instruments have been replaced, four other instruments in the Unit 1 reactor building will be replaced during the next outage for unit Procedures for monitoring of seismic instrumentation examined during this inspection are:
-
IP/1/B/125/1 -
Strong motion accelerograph verification monthly
-
IP/1/B/125/2A
-
2G peak recording accelerometer model PRA-400, calibration, quarterly
-
IP/0/B/125/3 -
Seismic trigger annual calibration
-
IP/11/B/125/4 -
Strong motion functional test, semi-annually
Review of records showed that surveillance tests required by these procedures were done on the following dates:
IP/1/B/125/01, September 30 to October 1, 1987 IP/1/B/125/2A, October 2, 1987 IP/O/B/125/3, September 30 to October 2, 1987 IP/1/B/125/4, September 18, 1987 Based on visual examination of seismic monitoring equipment, discussions of equipment operation and replacement of equipment with responsible engineers, and review of procedures and records for surveillance of seismic monitoring equipment, the inspector concluded that proper corrective measures were being taken to correct this deviation and that existing seismic monitoring equipment meets FSAR requirement This item remains open until the four 2G peak recording accelerometers are installed in the Unit 1 reactor buildin.
