e e FACILITY CHANGES REQUIRING NRC APPROVAL MONTH/YEAR: SEPTEMBER 1989 NONE DURING THIS PERIOD 13

MONTH/YEAR:

SEPTEMBER 1989 DC-84-70 PRESSURIZER SAFETY VALVE LOOP-SEAL INSULATION OVEN - UNIT 2 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 approxi-mately 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-88-36 CONTROL ROOM ENVELOPE HEATING, VENTILATING, AIR CONDITIONING (HVAC) INTERIM MODIFICATIONS - UNITS 1 & 2 This design change involved several modifications to the present equipment on an interim basis until larger capacity replacement equipment can be procured (approximately 24 months). The redun-dancy of certain equipment had been lost due to increased heat loads exceeding the rated capacity of the equipment.

Each of the air handling units had a redundant drive motor installed which was powered from a different power source. This will ensure operability of the air handling unit from a loss of the drive motor or it power source. In addition, the belt drive was modified to increase the fan speed and therefore increase the air flow and cooling capacity. The increased air flow through the ventilation ducting created the requirement to modify the ducting to keep the air velocity below 2,000 feet per minute (FPM).

One of the chillers and support equipment, i.e. chilled water and service water pumps and chilled water outlet MOV, was provided with a redundant source of power.

SUMMARY

OF SAFETY ANALYSIS This design change .restores the control room and emergency switchgear room Technical Specification design basis by ensuring that equipment and operational capability exists to compensate for normal and accident heat loads therein. The installation of the new motors will not affect other safety-related equipment or the qualification of the air handling units. The redundancy of the HVAC system is restored to provide single failure protection.

The added equipment is seismically qualified and seismically installed and supported.

. FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: SEPTEMBER 1989 SCAFFOLDING REQUEST 01-89 This request is to document the erection of temporary scaffolding located in the Emergency Service Water Pump House to support painting and associated preparatory work.

Installation of this temporary scaffolding was reviewed for effect on accident analyses and equipment operability/function.

Conclusion is that assumptions, bases and probabilities of accident analyses and equipment malfunctions are not affected.

TM-SZ-89-114 TEMPORARY MODIFICATION 01-89 Temporary Modification to document that "B" Reactor Coolant Pump Containment Isolation Valve for Component Cooling (TV-CC-205B) will be blocked open using a split schedule 80 pipe with clamps attached to the valve stem. This modification will be installed to maintain component cooling flow during certain testing performed at cold shutdown.

Technical Specification 3.8.A.l requires that containment integrity is maintained when in refueling mode or above cold shutdown. The isolation valve will only be blocked for the duration of the test. The valve will be returned to service prior to exceeding cold shutdown. Therefore, no unreviewed safety question is created.

TM-SZ-89-118 TEMPORARY MODIFICATION 04-89 This modification was to document that 2-DA-TV-200B was removed to allow repair. A spool piece was installed in its place to allow continued operation of the containment sump pump.

This Temporary Modification does not present an unreviewed safety question since the unit will be at cold shutdown throughout the Temporary Modification installation. 2-DA-TV-200A will remain operational allowing closure for isolation of the flow path from containment, if required.

AC-SZ-89-0909 ADMINISTRATIVE CONTROL 09-89 Administrative control will be maintained to ensure that TV-CV-250D will remain closed until it is operable. The solenoid leads will be lifted, the air to the solenoid will be tagged closed and the valve will be under Administrative Control.

Failing TV-CV-250D closed has been evaluated and it is determined that since the valve will be in its closed (accident) position the consequences or probability of any accident will not be increased. This change will not create an unreviewed safety question.
