Refer to the letter dated August 29, 1980, from R. L. Mittl to A. Schwencer for addi-tional information regarding items 27, 29, and 37.
Item 9.b(3) -
Installation of an Additional Smoke Detector in the New Spent Fuel Area - Completion date
.September 15, 1980 Item 27 -
Item 29 -
Item 32 and Item 36 Item 33 -
Item 37 -
M P80 89 03/2 Installation of Portable Radio System -
Com-pletion date November 1, 1980.
Ventilation-Dampers - Completion date November 1, 1980 Sprinkler System in Charging Area Auxiliary Feedwater Area and Diesel Oil Storage Tank Rooms -
Completion dated November 1, 1980 Halon System in Relay Room -
Completion date November 1, 1980 Fire Barriers -
Completion date November 1, 1980 The following items will be completed prior to April *1, 1981.
The expected completion date for each item is discussed below:
Alternate Shutdown Capability -
The design modifications to provide an alternate shutdown capability are quite extensive, requiring con-siderable new hardware and development of as-sociated procedures.
This design moQification will allow plant shutdown (hot shutdown) with-out the use of equipment, cables, and indica-tors that rely on the relay room and/or con-trol room.
This requires the installation of new transmitters both inside and outside the containment, cables, process instrumentation si~nal conditioning equipment, indicatots, power supplies, inverter, transformer, and electrical distribution cabinets.
Currently, equipment and procedures exist for achieving hot shutdown from outside the Control Room.
M P80 89 03/3 Alternate Shutdown Capability (Continued)
In addition to the hardware, procedures must be developed to direct local operation of pumps and valves for shutdcwn including any necessary modifications needed to achieve cold shutdown without equipment that may be damaged from a postulated fire.
In order to minimize the impact on plant op-eration, those items*requiring installation inside the containment will ~e completed prior to power operation.
The transmitters and cabling have been installed inside the con-tainment and will not require plant shutdown.
The remaining equipment has been ordered, giv-ing prior authorization to t*:-ie manufacturer for an overtime work schedul8, The last piece of equipment (process rack foe control equip-ment) is scheduled to be onsiL~ by January 1, 1981.
The installation of the ~emaining equipment, which includes system verification, procedure development, and preoferational testing, is scheduled for completion by March 2, 1981, at which time the system will be fully operational.
This installation should not require on outage and will proceed during power operation.
Cable tray wrapping will be completed last due to the desirability of installing all cables within a given tray prior to wrapping.
This eliminates the problem of unwrapping and re-wrapping in cases where additional cables ar~
installed.
These additional cables are due to changes to systems as a result of Corrunission imposed TMI related requirements.
The comple~
tion of all tray wrappings is scheduled for March 20, 1981.
