SEISMIC INSTRUMENTATION SYSTEM OPERATION 1.0 PURPOSE This procedure outlines the steps necessary for startup, operation and shutdown of the Seismic Instrumentation System.

2.0 PREREQUISITES 3.0 2.1 Placing the Seismic InstrumentationSystem in Service I&C has identified and loaded a cassette into SMA-3 recorder, AND*has performed a record calibration in accordance with its Departmental procedures.

2.2 Responding to a Seismic Event Alarm None 2.3 Removing the Seismic Instrumentation System from Service None PRECAUTIONS AND LIMITATIONS 3.1 Precautions 3.2 3,1.1 DO NOT handle OR operate any Seismic Monitoring Equipment while a seismic event is in progress as indicated by the Tape Machines running and/or the SMA-3 EVENT ALARM light is illuminated, 3.1.2 Alarms on the Seismic Response Spectrum Annunciator should be reset as soon as possible. NOT resetting the alanns will cause the power supply to fail in a short period of time (approximately 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />).

Limitations All Seismic M9nitoring Equipment operates automatically in response to a seismic event.

3.3 Interlocks 3.3.1 The Seismic Trigger is actuated by a seismic event.

WITH a magnitude of 0.01 gs (approximately 4.0 Richter)

OR more. The Seismic Trigger will perform the following:

  • Change the SMA-3 Event Indicator (flag) from BLACK to WHITE.

Tum the Strong Motion Accelerograph Tape Machines ON.

3.3.2 The amber SMA-3 EVENT ALARM light will only be Illuminated IF the 'SMA~3 Tape Machines are running.

. Once actuated by the Seisjnic Trigger, the Tape Machines will continue to run for 10 sec after the seismic event intensity falls below 0.01 gs.

3.3.3 The amber ALARM light on the Seismic Switch Power Supply drawer is: actuated by the Seismic Switch IF the magnitude of the seismic event exceeds 0.1 gs (about 5.S Richter). __

CAUTION 5.0 DO NOT handle OR operate any Seismic Monitoring Equipment while a seismic event is in progress as indicated by the Tape Machines running and/or the SMA.. 3 EVENT ALARM light is illuminated.

5.0 PROCEDURE 5.1 Placing the Seismic Instrumentation System in Service 5.1.1 5.1.2 5.1.3 Hope Creek ENSURE all prerequisites of Section 2.1 are satisfied.

PLACE the SMA3) STRONG MOTION ACCELEROGRAPH, (OSG~VY~7872 CONTROL PANEL) in-service by checking the following:

Key Switch is in OPERATE position AND key is removed.

AC ON lamp is illuminated.

EVENT INDICATOR is black.

PLACE the Seismic Switch Power Supply SP*lITS.3, (OSG-VY-7868 SEISMIC SWITCH) in service as follows:

OBSERVE that the AC ON lamp is illuminated.

  • (The CHARGE lamp may
  • OR may NOT be illuminated.)

B.. PLACE the TESTIRESET Switch in RESET AND REMOVE the key.

C.

5.2 Responding to a Seismic Event Alarm 5.2.1 PERFORM the following to determine Continued next page Hope Creek IF the seismic event has occurred or is in progress:

A.

IF a seismic event is iuprogress

  • AND is ~ 0.01 gs but < 0.1 gs, THEN OBSERVE the following:
  • The amber SMA-3 EVENT ALARM light should be illuminated.
  • The SMA-3 EVENT INDICATOR should be WHITE.
  • The 5 SMA-3 Tape Machines should be recording.
    • The amber ALARM light on the Seismic Switch Power Supply drawer should be extinguished.

B.,IF a seismic event ~ 0.01 gs

  • AND < 0.1 gs has occurred but is NOT in progress,

, THEN OBSERVE the following:

.* The amber SMA-3 EVENT ALARM light should be extinguished.

The 5 SMA Tape MacWnes should be advanced but NOT running.

  • The SMA-3 EVENT INDICATOR should be WHITE.
