PAGE 9 FACILITY CHANGES REQUIRING NRC APPROVAL MONTH / YEAR DECEMBER,1986 DC 85-05 Large Bore Snubber Modifications

, Unit 2 This design change replaced four of the pressurizer snubbers with fixed gap restraints; modified the snubber bolts of the steam generator upper restraints; eliminated two of the four-inch bore Bergen-Patterson snubbers on the reactor coolant supports; and modified the remaining steam generator supports and reactor coolan't pump supports.

Summary of Safety Analysis The modifications made to the reactor coolant system equipment supports do not change the design basis, functional requirements, or operation of the reactor coolant system and its associated equipment supports. The modified components have been designed to carry the same loads as required by the original design.

UNIT i

DC 81-103 Class IE Solenoid Operated Valve Replacement 2

This design change removed certain solenoid operated valves (SOV's) whose qualifications have not been demonstrated to be adequate. These valves were replaced with equivalent SOV's which have adequately demonstrated environmental qualification.

This design change was previously reported in September 1983. However, additional valves were added to the scope of the design change and is therefore reported a second time.

Summary of Safety Analysis The modification will provide additional assurance that the SOV's will perform their intended safety function during and following any postulated LOCA or HELB accident.

DC 81-119 NUREG-0696 Short Term I & C Project - Remote Multiplexer 1&2 (A & B)

Installation This design change provides a number of remote multiplexers and buffer units, which are the front-end portions of the Data Acquisition System (DAS). The DAS will collect and transmit required data, vital information, and plant status.

Summary of Safety Analysis The modification does not affect normal station operation j

nor the operation of any safety-related equipment. In the event of an accident or on-site emergency, the independent DAS provides a separate source of plant status

(

and information, therefore increasing overall plant safety.

MONTH / YEAR DECEMBER 1986 UNIT DC 85-08 Valve Monitoring System PORV and Pressurizer Safety Valves 1

This design change replaces the valve monitoring system fcr the pressurizer power operated relief valves and the safety valves with equipment which is environmentally qualified as required by Reg. Guide 1.97.

Summary of Safety Analysis The PORV's and SV's will provide more reliable indication of valve position during all modes of plant operation because of the redundant channels and the class IE, environmentally and seismically qualified devices. The replacement devices conform to the previous evaluation of the FSAR.

DC 85-09 Valve Monitoring System PORV and Pressurizer Safety Valves 2

This design change replaces the valve monitoring system for the pressurizer power operated relief valves and the safety valves with equipment which is environmentally qualified as required by Reg. Guide 1.97.

Summary of Safety Analysis The PORV's and SV's will provide more reliable indication of valve position during all modes of plant operation because of the redundant channels and the class IE, environmentally and seismically qualified devices. The replacement devices conform to the previous evaluation of the FSAR.

DC 85-17 Service Water Motor Operated Butterfly Valves Replacement 1

The service water motor operated butterfly valves, MOV-SW-103 A, B, C, and D, were replaced with high performance butterfly valves which incorporated enhanced design features to alleviate leakage and bending and were constructed of materials suitable for the service conditions.

Summary of Safety Analysis The changeout of the valves is a one-for-one replacement.

The high performance valves of enhanced design provide improved service in their operating environment. The valves do not alter or affect the system operation or the function of any safety related system. The valves are seismically qualified and seismically installed.

FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH / YEAR DECEMBER,1986 UNIT DC 85-18 Service Water Motor Operated Butterfly Valves Replacement 2

TM service water motor operated butterfly valves, MOV-SW-203A, B, C, and D, were replaced with high performance butterfly valves which incorporated enhanced design features to alleviate leakage and bending and were constructed of materials suitable for the service conditions.

Summary of Safety Analysis The changeout of the valves is a one-for-one replacement.

The high performance valves of enhanced design provide improved service in their operating environment. The valves do not alter or affect the system operation or the function of any safety related system. The valves are seismically qualified and seismically installed.

DC 85-33 Black Battery and Building Addition I

This design change installed a pre-engineered, metal" black" Battery Building on concrete foundation, located near the Turbine Building, adjacent to Unit I station transformer area, to house both Units 1 and 2 " black" batteries and associated equipment.

(Unit 2 " black" battery system will be installed under DC-85-35-2). The building will be provided with lighting, fire detection, gaitronics communication, heating, and ventilation systems.

This design change also installed a

" black" (nonsafety-related) 125V DC electrical battery and battery charging system. Large nonsafety-related electrical loads such as the emergency turbine oil pump (60 hp) and the air side seal oil backup pump (25 hp) will be powered from i

this system rather than the class IE,125V DC buses. In addition, part of the electrical heating, ventilation, and lighting loads of the " black" Battery Building will be powered from this system.

Summary of Safety Analysis This modification involves a nonsafety-related system in nonsafety-related areas, and will have no impact on j

any safety-related systems. It will improve the existing l,

class IE,125V DC system by assuming non-class IE loads to the black battery system. The new equipment will be designed, fabricated and installed to meet or exceed the requirements of the applicable sections of the Design l

Basis Document.

PAGE 13 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH / YEAR DECEMBER,1986 UNIT DC 85-35 Black Battery Addition 2

This design change installed a " black" (nonsafety-related) 125V DC electrical battery and battery charging system.

Large nonsafety-related electrical loads such as the emergency turbine oil pump (60 hp) and the air side seal oil backup pump (25 hp) will be powered from this system rather than the class IE 125V DC buses. In addition, part of the electrical heating, ventilation, and lighting loads of the black Battery Building erected under DC 85-33 will be powered from this system.

Summary of Safety Analysis This modification involves a nonsafety-related system in nonsafety-related areas, and will have no impact on any safety-related systems. It will improve the existing class IE,125V DC system by assuming non-class IE loads to the black battery system. The new equipment will be designed, fabricated and installed to meet or exceed the requirements of the applicable sections of the Design Basis Document.
