PAGE 11 F AGILITY CHANGES REQUIRING NRC APPROVAL MONTH/YEAR AUGUST 1988 NONE DURING THIS PERIOD

PAGE 12 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR

- - - -1988

- -AUGUST ---

DC 84-69 PRESSURIZER SAFETY VALVE LOOP-SEAL INSULATION OVENS UNIT l This design change installed metal reflective thermal insulation boxes which will enclose the safety valves loop seal piping. This is to maintain the loop seal water temperature at approximately 400°F. This temperature will allow part of the water to flash to steam after passing through the safety valves. The reduced density of the watersteam mixture will cause reduced fluid transient loads for the piping and supports.

SUMMARY

OF SAFETY ANALYSIS The installation of the boxes will not affect the operation of the pressurizer or the safety valves. The boxes will reduce fluid transient loads to ensure the piping and supports are qualified for the design basis transients once the supports have been modified. The boxes do not affect any safety related system or component and does not impact any Technical Specification.

DC 86-15 LEVEL INSTRUMENTATION TO PREVENT LOSS OF SHUTDOWN COOLING UNIT l This design change installed a permanent standpipe arrangement to replace the temporary polyhose arrangement installed during each outage.

Local level indication, control room indication and a control room low level alarm are provided for reactor coolant level during outage periods.

SUMMARY

OF SAFETY ANALYSIS The system will be placed into service only during cold shutdown conditions. At all other times the system is isolated from other systems.

The portion of the system up to and including the second isolation valve is designed to reactor coolant design pressure and temperature. This system does not affect safety related equipment or the operation of the safety related systems.

DC 87-32 WEED 9007 RTD REPLACEMENT UNIT l This modification replaced the eighteen (18) narrow range RTDs with RTDs which have adequately demonstrated environmental qualification as set forth by NUREG 0588 Category 1.

SUMMARY

OF SAFETY ANALYSIS The replacement RTDs are essentially one for one replacements of an enhanced design and will not affect any of the operations or ability of equipment important to safety to perform their safety functions.

PAGE 13 FACIIJT.ANGES THAT DID NOT REQUIR.RC APPROVAL MONTH/YEAR AUGUST 1988 AC S2-88-0615 ADMINISTRATIVE CONTROL 08/04/88 This change provides administrative control while closing MOV-SW-205B or MOV-SW-205D in order to accomplish maintenance on the associated valve.

Since the valves (MOV-SW-205B and 205D) will remain operable and will be manually opened prior to auto or manual start of the recirculation spray (RS) pumps, the change will not affect the operation of the RS system. Therefore, no unreviewed safety question is created.

AC S2-88-0805 ADMINISTRATIVE CONTROL 08/05/88 This change maintained recirculation spray (RS) heat exchangers service water discharge valves 2-SW-MOV-205B & D closed under administrative control to prevent service water ingress to the recirculation spray heat exchangers from the discharge tunnel to prevent biofouling of the RS heat exchangers.

Since the valves (MOV-SW-205B and 205D) will remain operable and will be manually opened prior to auto or manual start of the RS pumps, the change will not affect the operation of the RS system. Therefore, no unreviewed safety question is created.

FS 88-40 FSAR CHANGE REQUEST 08/09/88 Design Change 77-09 modified the usable volume of Unit 1 and Unit 2 R WSTs. The modification affected LC Os for safety injection and*

containment spray systems.

The 10 CFR 50.59 review resulted in no unreviewed safety question since DC 77-09 did not alter the basic design function of the affected systems.

TM S2-88-60 TEMPORARY MODIFICATION 08-19-88 This modification allowed the lead from terminal board 58C-2 to 2AST 1 to be lifted and prevent the mechanical anti-motoring trip from operating.

Removal of the mechanical anti-motoring trip will not have an adverse effect on the turbine overspeed or loss of electrical load analysis.

Therefore, there is no unreviewed safety question.

TM Sl-88-132 TEMPORARY MODIFICATION 08/20/88 A jumper was installed from the sample connection of the VCT gas space to the sample connection of the gas stripper surge tank at the sample sink.

Venting the VCT via the sampling system will not increase the probability of an accident nor increase the consequences of an accident. Protection to the system is provided by relief valves in the system. Hose and fittings are rated in excess of operating pressures for the systems. Therefore, no unreviewed safety question is created.

A PAGE 14 FACIUT.ANGES THAT DID NOT REQUIRlaRC APPROVAL MONTH/YEAR AUGUST 1988 AC Sl-88-810 ADMINISTRATIVE CONTROL 08/20/88 AC S2-88-8 IO While the charging pump component cooling (CC) pump's drain valve is open to feed and bleed the system to increase chromate concentration, an operator will be stationed at the drain valve to close it immediately should the head tank level drop .s_ 30%.

Feeding and bleeding the charging pump CC system by opening the charging pump CC pump's drain valve will not affect the operability of the charging system. It will enhance corrosion control by the addition of chromates. Therefore, this administrative control does not constitute an unreviewed safety question.

AC Sl-88-0820 ADMINISTRATIVE CONTROL 08/20/88 This change maintained recirculation spray (RS) heat exchanger (HX) service water (SW) discharge valve (1-SW-MOV-lOSA) closed under administrative control to prevent SW ingress into the RS HX from the discharge tunnel to prevent biofouling of the RS HX.

Since valve 1-SW-MOV-lOSA will remain operable (as per EWR 88-326) and will be opened prior to auto or manual start of the RS pumps, the change will not affect the operation of the RS system. Therefore, no unreviewed safety question is created.

AC Sl-88-0821 ADMINISTRATIVE CONTROL 08/21/88 This change allowed manual control over the 'C' RSST tap changer with constant communication with the control room due to failure in the automatic control.

Manual control of the 'C' reserve station service transformer tap changer is required due to a failure in the automatic system. Manual control ensure voltages on the emergency buses will remain in spec and will reduce the chance of loss of offsite power to 1H and 2J emergency buses. Manual operation will maintain voltages within the intent of GDC 17.

AC Sl-88-0823 ADMINISTRATIVE CONTROL 08/23/88 The dike at the emergency switchgear room was temporarily removed and a flood watch was placed at the door and at the turbine building pit areas. The dike was reinstalled in the event of a flood.

The removal of this dike will not adversely affect any safety related equipment or create an unreviewed safety question.

PAGE 15 OCEDURE OR METHOD OF OP AT DID NOT REQUIRE NRG APP MONTH/YEAR AUGUST 1988 l-TOP-2027 TEMPORARY OPERATING PROCEDURE 08/01/88 This change provided a means for flushing the primary drains transfer tanks (PDTT) discharge lines to the primary drains tanks (PDT) and to inspect PDTT pumps discharge check valves to clear/identify blockage in PDTT discharge lines.

An unreviewed safety question does not exist because the probability and consequences of a liquid waste release are unaffected. All liquid waste released from the check valves will be contained and directed to floor drains and the containment sump. Flush water will also be directed to the PDT and will be contained. Any uncontrolled release will be stopped by closing l-DG-74. This valve can also be immediately shut if containment isolation is necessary.

JUSTIFICATION FOR CONTINUED OPERATION 08/11/88 This Justification for Continued Operation documents plant operation with three out of four Radiation Monitoring Pumps operable on Service Water Discharge Lines from Recirculation Spray Heat Exchangers (RSHX).

The reviewed condition does not affect the function of the RS system. Significant increases in exposure or releases will not occur because a backup radiation monitor exists and under the postulated failure of the RSHX, the heat exchanger can be

• isolated without reducing the required heat removal via the RS system. Therefore, an unreviewed safety question does not exist.
