ENCLOSURE I 1.
OPERATIONS
SUMMARY
A.
Changes in Facility Design 1.
The following changes did not require prior commission approval but were reviewed by PORC.
It was agreed that each did not involve any unreviewed safety questions as defined in 10CFR50.59(a)(2) based on the information presented, a)
PDCR 80-05, RCIC Auto Restart PDCR 80-05 was completed on 1/25/82 This PDCR modified the P.CIC trip / throttle valve so that it would automatically reset when the RCIC System trips on high reactor water level. The RCIC would then be ready to be initiated manually or automatically. This capability is a commitment to NUREG-0737, Item II.K.3.13.
b)
PDCR 81-08, RWCU Sampling System Modifications PDCR 81-08 was completed 1/22/82.
The PDCR was designed to help limit trace Cobolt originating in the Sampling System. Existing sample root valves were replaced with valves utilizing Nitronic 60 Discs, bonnets and seats in the RWCU, Condensate, and Feedwater Sampling Systems. A new sample point was added to the RWCU System, stainless steel sampling lines were replaced with titanium lines and three new sampling panels and instrument racks were installed in support of the ongoing EPRI Program to collect data on chemical changes in the Reactor Coolant System during plant operations, c)
PDCR 82-05, Purge and Vent Valve Limiters PDCR 82-05 was completed 5/25/82.
This PDCR limits the maximum opening of SB16-19-6 to 400 and SB16-19-7 and 7A to 500 This was done in response to an NRC question regarding the seismic qualifications of these valves and provides added assurance that the valves will close under accident conditions.
d)
PAR 80-06, A0G Closed Loop Cooling Water System PAR 80-06 was completed 7/20/82.
This PAR installed ar air to water closed loop cooling water system in the Advanced Offgas (A0G) Building. This system will; 1) correct corrosion and silt deposition problems that currently exist in the A0G Service Water System, and b) replace the present service water cooling to A0G.

e)
PAR 80-28, Nnw Warahsuse PAR 80-28 was completed 2/22/82.
This PAR built the south wing of the plant complex that contains expanded receiving, shipping, and storage
. facilities, the plant Training Center, and offices for the Maintenance and Stores Departments.
f)
PAR 80-32, Containment Inerting Instrumentation and Makeup Feed Line PAR 80-32 was completed 5/1/82.
This PAR installed and/or. modified existing plant l
equipment as required to supply nitrogen to applicable plant locations for the short term and transition to long-term inerting.
?
g)
PAR 80-41, Technical Support Center (TSC) Radiation Monitoring PAR 80-41 was completed 2/17/82, 1
This PAR installed four area radiation monitors and one cart mounted continuous air monitor in the location designated as the TSC.
h)
PAR 81-17, Supplement 1, Standby Liquid Control (SLC)
Cleanup System-i PAR 81-17, Supplement 1, was completed 3/23/82.
This alteration installed a flow meter to the SLC test l-line to aid in periodic pump performance measurements, i
I i)
PAR 81-31, Iodine Post-Accident Sampler PAR 81-31 was completed 3/1/82.
This PAR installed a new iodine / particulate sampler in the Victoreen Room (Stack Base).behind lead shielding. The i
new sampler consists of a particulate filter and a silver zeolite cartridge with quick disconnects to minimize radiation exposure, j
j)
PAR 82-02, H2 Seal Oil / Lube Oil Auto Actuation PAR 82-02 was completed 7/28/82, 1
i This PAR provided for the automation of the Fire Uater Sprinkler Systems in the Lube Oil Room and H2 Seal Oil i
Room. In addition, four sprinkler heads in the H2 Seal
]
Oil Room were replaced with fusible heads.

k)
PAR 82-06, Oxygen Injection System PAR 82-06 was completed 8/25/82.
This PAR addressed task-5 of EPRI 1934 Program, "BWR Radiation Control Plant Demonstration", which required the installation of an Oxygen Injection System. This system-will regulate the dissolved oxygen' concentration in the Feedwater System to a level of 100 ppb + 10 ppb.
1)
PAR 82-13, Fuel Pool Makeup Meter PAR 82-13 was installed 6/22/82.
This PAR installed a flowmeter in the demineralized water line from service box number 11 to the spent fuel pool in order to provide direct indication to spent. fuel pool makeup requirements, m)
MR 82-0836, Air Supply to the Respirator Fitting Room MR 82-0836 was completed 1/12/83.
This Maintenance Request (MR) extended the plant Service Air System to the Respirator Fitting Room in the plant Training Center.
B.
Tests or Experiments 1.
The following tests or experiments did not require prior-commission approval, but were reviewed by PORC. It was agreed that each did not involve any unreviewed safety questions as defined in 10CFR50.59(a)(2) based on the information presented.
I STP 82-01, Control Room Air Inleakage Test STP 82-01 was completed 6/18/C2.
A special test was conducted to determine Control Room air inleakage. The test utilized a method which conforms to the ASTM Standard E-741-80, " Measure Air Leakage by the Tracer Dilution Method".
C.
Safety and Relief Value Failures and Challenges During 1982 there were no challenges to, or failures of, the safety and reliaf valves.
