Salem Generating Station, Unit 2 Public' Service Electric & Gas Company Hancocks Bridge, New Jersey 08038 IpENTIFICA22ON 07 OCCURRENCE:

Overpressure Protection System - Channel 2 Activation

~

CONDITIONS PRIOR TO OCCURRENCE:

Mode 5 - Rx Power 0% - Unit Load OMW DESCRIPTION OF OCCURRENCE:

While technicians were zeroing the E/P controllers fcr pressurizer spray valves, 2PS1 and 2PS3, pressure in the Reactor Coolant System (RCS) increased from 330 psig to 360 psig.

This occurrence initiated POPS Channel 2 while RCS temperature was at 175'F and a bubble in the pressurizer.

Action Statement 3.4. 9.3c was entered at 14 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> on May 15, 1981 for the activation of the POPS.

This occurrence constituted a special report IAW Technical Specifi-cation 6.9.2.

DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

Personnel error.

The technicians' supervisor informed them that he would notify the Shift Supervisoc, this was not done prior to commence-

't. tent of the work.

ANALYSIS OF OCCURRENCE:

Work Order #934960 was issued for the calibration of the E/P controllers for valves 2PS1 and 2PS3.

Following normal calibration procedures, these valves were closed, which in turn caused an increase in the Reactor Coolant System pressure.

The pressure increase from 330 psig to 360 psig, initiated the POPS Channel 2 reducing RCS pressure within 45 seconds.

The operation of the POPS within its design parameter prevented the pressure transient from exceeding pressure temperature limitations.

l Technical Specification 3.4. 9.3c requires that in the event the POPS is used to mitigate a RCS pressure transient, a Special Report shall j

be prepared and submitted to the Commission purtuant to Specification 6.9.2 within 30 days.

CORRECTIVE ACTION

The Supervisor _was instructed in the proper method of implementing work orders.

Action Statement 3.4. 9.3c was terminiated at 1431 hours0.0166 days <br />0.398 hours <br />0.00237 weeks <br />5.444955e-4 months <br /> on May 15, 1981.
