1.0 NARRATIVE | |||
==SUMMARY== | |||
OF OPERATING EXPERIENCE AND MAJOR SAFETY R$LAlED MAINTENANCE 1.1 Summary Except for some minor short-term load reductions, the plant operated at 70% power until the end of the month. . | |||
On September 30, while performing a surveillance on the plant protection system, a spurious trip caused a loop shutdown followed by a turbine trip and reactor scram. | |||
This terminated about 31/2 months of continuous operation. | |||
Plans are underway to complete required surveillances and make the necessary repairs to return to power operation. | |||
1.2 Operations Pesctor power was generally maintained at about 70% | |||
throughout the month with the following exceptions. | |||
Reactor power was decreased to about 67% to remove 1A boiler feedpump from service to repair its discharge check valve. The 1A boiler feedpump was repaired, and power was increased to 70% on September 3. | |||
At 1304 hours on September 8, a system frequency upset occurred causing a turbine and reactor power runback of about 30 megawatts. Plant power was returned to 70% by 1545 hours. | |||
On September 27, between 0100 and 0530 hours, plant load was decreased to 180 MWe at the request of the system dispatcher. At 0835 hours, there was a turbine runback to about 66% when a backup bearing water safety valve opened spuriously. | |||
On September 30 at 0548 hours, while performing a Surveillance Test on the ultrasonic pipe rupture detection system, a spurious trip caused a Loop 1 shutdown. Rapidly decreasing main steam temperature in the remaining loop subsequently caused a turbine trip and a two-loop trouble scram. | |||
. At the end of the month, the reactor was shutdown. | |||

We are experiencing some difficulty with our condensate /feedwater systems. High and variable concentrations of chlorine in the domestic water supply appears to be causing rapid exhaustion of the makeup and condensate polisher resin. This results in decreased capability to make up to the condensate system, as well as increased consumption for regeneration. | |||
On September 14, a mobile makeup domineralizer was brought on site. By September 18, this unit processed-300,000 gallons of water to regenerate all exhausted resins and fill the storage tanks. Although the domestic water supplier has indicated they are taking corrective measures, chlorine, as well as insufficient supply capability, remain to be problems. | |||
A fire drill was conducted on September 13 in which the Platteville Fire Department participated. In addition, , | |||
fire drills were conducted on September 20 and on September 27. | |||
Contract personnel began arriving on September 15 to begin | |||
<' work on the refurbishment of the outside auxiliary boiler. | |||
! i-Among other things, new internals are being installed in the upper drum, a heating coil is being installed in the lower drum, and brick work is being repaired. | |||
Helium purification train IB broke through on September 22. | |||
When the operators tried to isolate the train for i regeneration, it was found that HV-2302, the train inlet , | |||
valve, was bound up and would not close using the motor. , | |||
Attempts to close the valve using the the handjack were not successful. This valve is in a well in the top of the prestressed concrete reactor vessel and cannot be repaired until the reactor is shut down and depressurized to less than 100 psia. | |||
A new replacement tube bundle for heater #5 arrived on site. The old heater #5 was moved down to the railroad bay on September 15. The shell was removed from it and the bundle was removed from the site. | |||

The presence of reserve shutdown material in control rod drive region 27, confirmed in August, was evaluated by General Atomic Company. A conservative analysis indicated that the potential exists for operation in a mode outside the limits of LCO 4.1.3.

licensed capacity. I
- The 1992 estimated date is based on the understanding that spent fuel discharged during the term of the Agreements will be stored by DOE at the Idaho Chemical Processing Plant. The storage capacity has evidently been sized to accomodate eight fuel segments. It is estimated that the eighth fuel-segment will be discharged in 1992.
