DC 84-51 PAGE 10 FACILITY CHANGES THAT DID NOT REQUIRE NRG APPROVAL MONTH/YEAR April 1988 STATION PERSONNEL FACIIJTIES RENOVATION This design change added a second story over part of the service building and a two story addition to the west end of the service building.

The spaces allocated to Chemistry, Health Physics and the Instrument Shop were enlarged and/or relocated in the same general area. The laundry and warehouse facilities were relocated to other areas of the station.

Additional office spaces, locker rooms with toilet facilities and a PBX room were installed.

SUMMARY

OF SAFETY ANALYSIS The control room annex and the slab roof over the relay room, cable vault and mechanical equipment room No. 3 have not been degraded structurally, seismically or with respect to missile protection.

The loading on these structures has been minimized.

The new CMU wall at column line 10 has been designed so as not to fail and damage the control room annex door or wall during a seismic event. The structural integrity of the Turbine Building has not been affected.

The additional loading on the service water discharge tunnel has been reviewed and found to be acceptable.

The main steam and main feedwater piping will be unaffected by these modifications.

The ability of chiller l-VS-E-3A or 3B (and associated pump l-VS-P-3A or 3B) to provide a backup control room chilled water supply in the unlikely event of a fire which disables all three control room chillers will not be affected.

The relocation of the breathing air compressor to the loss prevention storage room will not reduce access of the fire brigade to breathing air.

These modifications are non-safety-related and do not affect the design basis, operation, or control of equipment important to safety.

No accidents or malfunctions previously evfil.uated will be affected and no new accidents or malfunctions will be created.

FACIIJTY CHANGES THAT DID NOT REQUIRE NRG APPROVAL MONTH/YEAR SCAFFOLD REQUEST April 1988 A temporary platform was located in the Unit 1 containment electrical penetration area to work pipe and hanger installation !AW DCP-86-15.

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.

AC SI-88-0423 ADMINISTRATIVE CONTROL The dike at the emergency switchgear room door was temporarily removed and a flood watch placed at the door and turbine building sump areas.

The dike would be reinstalled in the event of the flood.

The removal of this dike did not adversely affect any safety related equipment or create an unanalyzed accident.

AC S2-88-0424 ADMINISTRATIVE CONTROL TM Sl-88-42 A flood watch was posted at mechanical equipment room (MER) #3 while the flood dike was removed.

The operator would isolate the line if a break occurred in MER #3 until the flood dike was replaced. If the line break occurred downsteam of MER #3 the Turbine Building operators would isolate the line break.

Since administrative control will ensure flood protection of safety related equipment, an unreviewed safety question is not created.

TEMPORARY MODIFICATION This temporary modification was required to provide a letdown flow path for reactor coolant system clean up while work was being done on the letdown trip valve TV-1204.

The requirements of containment isolation will be met because the jumper will be removed prior to leaving cold shutdown and the trip valve (TV-1204) will be operable.

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.

TEMPORARY MODIFICATION This temporary modification was required to i!).stall a flexible hose from l-DG-74 to l-CH-413 maintaining the following valves shut: MOV-1381, l-DG-TV-108A, HCV-1522A,B,C and HCV-1523.

Since the installation was verified for leak tightness, and the design specifications for the hose used exceed expected pressure and temperature, and possible leakage paths were contained, and possible dilution paths were isolated, no unreviewed safety question was created.

SCAFFOLD REQUEST A

temporary platform was located in Unit 1

containment 316 11 annulus to install conduit from cable trays to location of new transmitters on the wall.

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.

ENGINEERING WORK REQUEST This engineering work request replaced the existu_:ig liquid waste demineralizer with Duratek skid mounted package system of demineralizer,

filters, pump, instrumentation, associated piping, etc.

The new system improves waste processing efficiency and reduces personal exposure to radiation.

The system is fully tested and inspected.

Failure of equipment is analyzed in the UFSAR. No unreviewed safety question involved.

OPERA TING PROCEDURES (OP)

These procedural changes were required to recognize the normal positions of the RHR pump seal vents and constant casing vents. and to recognize RH-MOV-200 as lock closed.

These changes updates the normal positions of the RHR pump seal and casing vents to open and as such have no affect on the consequence or probability of any analyzed accident/malfunction and does not create any new accident/malfunction sequences.

These changes will ensure the pump casing/seals remain vented.

AC Sl-88-0418 ADMINISTRATIVE CONTROL Administrative control was required to close the door between the emergency switchgear room and the turbine building.

The door was blocked open to allow access for an exhaust duct for maintenance work.

The design basis accident was reviewed and it was determined that since the emergency switchgear door would be closed by the dedicated continuous fire watch when the control room is required to be pressurized, an unreviewed safety question did not exist nor is a technical specification change required.

....... p_ril_l9_8_8_

DEVIATION REPORT The 'B' and 'C' control room/relay room chiller units are not 100% capacity (90 tons) as described in the UFSAR. The change involved operation of the system under more restrictive conditions in order to be

  • consistent with the mode of operation described in the UFSAR.

If service water (SW) temperature at the inlet of the control room/relay room (CR/RR) chillers is limited to 70°F, then a single chiller unit is capable of maintaining the CR/RR spaces below 100°F. The equipment in the CR/RR is designed to 120°, therefore, plant operation with one chiller operating and one chiller operable (per technical specifications) provides the necessary redundancy such that no unreviewed safety question is created.

Operation with SW temperature in excess of 70°F requires that all three CR/RR chillers be operable which provides for 100%

redundancy, so that no unreviewed safety question is created.

Subsequent to the performance of this safety analysis, the 'B' chiller was restored to 100% capacity. The upgrade on 'C' chiller is in progress. Service water temperatures have not yet reached. 70°F.

AC S2-88-0419/ ADMINISTRATIVE CONTROL AC S2-88-0420 The 'A' feedwater regulating valve was jacked open~-

MOV-FW~254A throttled and 'A' S/G level was controlled on the bypass, FCV-255A.

An operator was stationed at 'A' feedwater regulating valve to shut the valve should feedwater isolation be required by an automatic signal. The operator was in contact with the control room by way of a radio and could close the feedwater regulating valve in thirty seconds if required..

AC Sl-88-0421 ADMINiSTRATIVE CONTROL Administrative control (reactor operator notification by the gaitronics system) of the high flux at shutdown alarm system was taken because the evacuation alarm in containment was inoperable.

Using the gaitronics to evacuate containment in lieu of the evacuation alarm, should a high flux condition exist, has no impact on the UFSAR safety analysis.

PAGE 18 PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR April 1988 AC S2-88-0426 ADMINISTRATIVE CONTROL 04-26-88 Administrative control was required to perform maintenance on the limit switches for TV-:DA-203A, and to comply with the technical specification for containment integrity.

The containment isolation valve TV:-DA-203A will be closed and under administrative control to provide containment integrity, but can be operated within two hours if a sample is needed.

Therefore, an unreviewed safety question does not exist.

AC SI-88-0427 ADMINISTRATIVE CONTROL Administrative control was required to close mechanical equipment room #3 door and emergency switchgear room/turbine building door.

The doors were blocked open to allow access for welding hoses, cables and air hoses to perform work on l-VS-E-4B/4C.

The design basis accident was reviewed and it was determined that since the mechanical equipment room

  1. 3 door and emergency switchgear/turbine building door will be closed upon receiving an safety injection signal, the control room pressure boundary will be satisfied.

1&2-0P-62.1/

OPERATING PROCEDURES 2-0P-12A UFSAR 11.3.3.8 states that all three steam generators blowdown flows are through one radiation monitor.

These procedures align two steam generator blowdowns to flow through one radiation monitor and the remaining steam generator blowdown to flow through the other radiation monitor.

Changing the steam generator blowdown radiation

. monitor flow alignment from flowing through one radiation monitor to flow through

  • two radiation monitors enhances the ability to detect primary-to-secondary leakage.

Therefore, SGTR accident and consequences are unaffected.

PAGE 21 TESTS AND EXPERIMENTS THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR APRIL 1988 SPECIAL TEST This special test was used to verify the auxiliary feedwater flow paths to 'A' steam generator to ensure that there were no obstructions in the line.

This test was performed when Unit 2 was at cold shutdown and only a motor driven pump was used for the test; therefore, no effect was identified in I0CFRS0.59/10CFR72.35 review.
