NINE MILE POINT UNIT 1 Table 2

- Modifications Implemented Under 10CFR50.59 Not Previously Submitted to the Nuclear Regulatory Commission*

Mod. Number Modification Descri tion 78-04 Install nitrogen supply valve in Train 11 of the containment atmosphere dilution system 78-21 Add welding outlets on elevation 198 of Reactor Buil ding 80-90 Modify turbine generator sequential trip circuit by adding "motoring" relays to provide overspeed protection by verifying that all steam sources are closed off before opening turbine-generator breakers.

81-27 Replace breathing air service water compressor with duplex strainers 'Y'trainers 81-36 Install manual (normally locked-open) isolation valve in nitrogen supply line to containment atmospheric dilution system for maintenance.

82-03 Change detect zones (D-1114 8 DA-1114) H2 seal oil from Class A to Class B. Ref. NRC's SER to Amendment 30. Ir 82-33 Modify turbine thrust bearing wear detectors per GE technical information letter.

82-57 Install Reactor Building sprinkler system drain tank level switch column isolation val-ve and testing tee.

Provide level switch probe clearance and valve tee assembly for calibration.

82-69-1 Upgrade the feedwater low flow control during startup, shutdown and hot standby to resolve NUREG-0619 feedwater nozzle cracking (thermal cycles) concerns.

Also modified the motor driven feedwater recirculation system.

82-69-3 Install redundant high pressure coolant injection initiation circuits for reliability.

• While some modifications may have been performed earlier, inclusion indi cates cl oseout of the entire modi fi cati on package.

Page 2 Mod. Number Modification Descri tion 82-80-5 Revise logic on emergency condenser vent isolation valves to include confirmatory logic.

83-16 Replace waste collector filter recycle pump with pump made by Gould. (Base and piping also modified).

Original vendor (Delaval) no longer manufacturers this pump, which was leaking at the casing flange and could not be repaired.

83-30 Replaced Turbine Building closed loop cooling heat exchangers ll 5 12.

83-30-2 Replace closed loop cooling heat exchanger (part of 83-30 above) 83-35 Addition of roof alarm (23') and camera at northwest wall of security annex.

83-36 Additional document control (NSR) electrical outlets to support additional office space and equipment for records storage, drawing control room and computer tech shop.

83-46 Prime computer; power upgrade - add 16 outlets (RM246-1) to accommodate additional computer peripherals and communications equipment.

83-81 Upgrade Reactor Building fire barrier wall (NSR) piping penetration seals to 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> IEEE-634.

84-19 Cut and relocate section of breathing air pipe so that post-LOCA vent line may be installed at Reactor Building El 281'.

84-29 Accurex Upgrade - To provide reliable use of the fuel zone water level monitoring system hardware/software mod's per GE FDI NTCB.

84-31 Replace the power cable to the reactor shutdown cooling system return line isolation valve motor-operator and DC valve board (outside the drywell.) with a larger cable to improve performance by minimizing motor burnout.

84-35 Relocate 3 smoke detectors in digital computer room (auxiliary control room) to avoid discharge from air supply diffuser, per NRC Inpsection 84-06.

84-50 Modify twelve input risers to Waste Disposal Building Sump 813 to minimize stoppage in floor drains and consequential contamination.

P a

Page 3 Mod. Number Modification Descri tion 84-51 Screen wash pump; replace with mechanical seals. Also changed butterfly valve to plug valve.84-004 Replace diesel fire pump governor inlet and discharge and pump bearing oil solenoid valves to provide manual start capability upon loss of power.85-012 Relocate supply voltage source for cleanup system isolation valves from powerboard 167 to 1618 8 171B and add thermal overload bypasses to satisfy environmental qualifications.
