This report contains the highlights of the Fort St. Vrain, Unit No. 1 activi-ties, operated under the provisions of the Nuclear Regulatory Commission Operating License, DPR-34 This report is for he month of April,1980, 1.0 NARRATIVE SUlefARY OF OPERATING EXPERIENCE AND MAJOR SAFETY RELATED MAINTENANCE 1.1 S ummary On April 1,1980, the reactor power was increased from 45% to 60%,
190 megawatts electrical, and held approximately at this level pending cleanup of the nrimary coolant oxidants.
"D" circulating water pump expansion bellows ruptured and required isolation pending repair.'
Experienced problems with the reverse osmosis unit in that the re-jection rate was unacceptable. The unit was chemically cleaned, and the membrane seals were replaced on April 2, which corrected l the problem.
On April 2,1980, problems developed with the backup bearing water system, which was traced to improperly working control valvea. The problem was corrected and backup bearing water system vas placed l in service.
On April 4,1980, reactor power was being maintained at 68 mega-watts when total oxidants increased sharply to approximately 50 ppm. l Electrical load was reduced to 185 megawatts. The sudden increase in oxidants is believed to be caused by a malfunctioning helium recovery compressor. The buffer flows to all circulators were re-duced and the recovery compressors vented. By April 5, primary !
coolant oxidants were reduced to 40 ppm, with reactor power being maintained at 56%. During this period, "B" circulator buffer j knock-out pot required draining frequently. One attempt to drain <
the knock-out pot resulted in tripping "B" circulator off line. l "B" circulator was recovered for normal operation. At this time, (April 7), it was decided to take "B" circulator down to investigate '
what effects it might have on the ability to reduce total oxidants. '
On April 8,1980, while operating at 150 megawatts electrical, a i loop shutdown was received during an attempt to restart "B" circu- '
lator. The recovery of the loop was severely hampered by frequent loss of power to secondary coolant drain path valves. Utis loss of power was caused by blown fuses. A testing system, which is still in progress, was initiated to determine the cause. {
j The loop was recovered and reactor power was increased to support 65 megawatts electrical load on April 9, 1980. Region outlet
- temperatures were being controlled below 1200*F until total oxi-3
- dants decreased below 10 ppm. Reactor power was changed over the next few days between 30% and 65% as dictated by primary coolant
{ oxidant levels. The "B" and "C" circulators were removed from i

1.0 NARRATIVE
SUMMARY
OF OPERATING EXPERIENCE AND MAJOR SAFETY RELATED 1 MAINTENANCE (Cont'd) i 1.1 Summarv (Cont'd) service during this period (April 10 to April 18, 1980) to observe the effect, if any, on moisture ingress. No effect was observed. .
On April 18, 1980, while operating at 35% power, a turbine trip occurred from a spurious signal from the plant protective system while changing out a logic module. The same day, a Loop 1 shut-down occurred when buffer supply was disturbed to Loop 1 circulators caused by the relief action of "A" circulator penetration rupture disk.
l The reactor remained in a low power condition (2% to 10%) until April 21, 1980, to allow license candidates to complete required !
Nuclear Regulatory Commission reactor starts.
Reactor power was raised to approximately 30% on April 23. On this l date, "B" circulator tripped from seal malfunction problems. The l circul- sr was restarted and power raised to 50% until an increase in or . ants required lowering region outlet temperature below 1200*F.
On April 25, a loop shutdown occurred, caused by a faulty plant protective logic module. The loop was recovered and reactor power was increased to approximately 30%.
The plant was shutdown to one loop operation on April 28, 1980, again due to a malfunction in the plant protective system. Investi-gation revealed a failed chip in a logic module. The loop was recovered and load increased to 130 megawatts.
On April 30, 1980, another loop shutdown occurred when "A" and "B" bearing water pumps tripped off as a result of construction work being performed in the area of the Loop 1 surge tank. Recovery of the loop was accomplished, and the load was increased to approximately 130 megawatts.
1.2 Testing Testing completed during the month of April, 1980, was the normally scheduled Surveillance Tests.

- The 1986 date is based on the understanding that spent fuel discharged during the term of the Three Party Agreement will be shipped to the Idaho National Engineering Laboratory for storage by DOE at the Idaho Chemical Processing Plant (ICPP). The storage capacity has evidently been sized to accomodate fuel which is expected to be discharged during the eight year period covered by the Three Party Agreement.
