Oparntions Summary March 1985 The following summary describes the significant operational activities for the month of March. In support of this summary, a chronological -

log of significant events is included in this report.

Unit 1 Unit I was critical for 744.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />, produced 878,860 MWH (gross), resulting in an average hourly gross load of 1,181,263 kW during the month. There are 86.3 full power days estimated remaining until the end of cycle 3 fuel.

The capacity factor for the month was 99.9 percent. The cycle 3 refueling outage is scheduled to start on September 6, 1985.

During the month, the unit experienced no reactor scrams, manual shutdowns, or power reductions.

Unit 2 Unit 2 was critical for 744.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />, produced 872,320 MWH (gross), resulting in an average hourly gross load of 1,172,473 kW during the month. There are 281.4 full power days estimated remaining until the end of cycle 3 fuel.

The capacity factor for the month was 99.1 percent. With a capacity factor of 85 percent, the target EOC exposure would be reached February 26, 1986.

During the month, the unit experienced no reactor scrams, manual shutdowns or power reductions.

Significant Operational Events EE.it 1 Date Time Event 03/01/85 0001 The reactor was in mode 1 at 100% power producing 1190 MWE.

03/31/85 2359 The reactor was in mode 1 at 100% power producing 1180 MWE. The unit has been in continous operation since September 28, 1984 (184 days).

The units 878,860 MWE (gross) and 99.9%

capacity factor is a record for the unit.

Unit 2 03/01/85 0001 The reactor was in mode 1 at 100% power producing 1190 MWE.

03/31/85 2359 The reactor was in mode 1 at 100% power producing 1180 MWE. The unit has been in continous operation since February 17, 1985 (42 days). -

. Spent Fuel Pit Storage' Capabilities 4 Sequoyah hasi t he capabilities'to store'1,386 spent fuel assemblies.

Two-hundred-seventy-six assemblies _are presently stored in the SFP'

- withL the capacity to store an additional 1,110 assemblies.

.PORVs and Safety Valves Summary No PORVs'nor safety valves were challenged during the month.

Licensee Events-and Special Reports

-The following. licensee event reports (LER) were sent during March 1985 Lto .the Nuclear Regulatory Commission.

LER DESCRIPTION OF EVENT 11-85011 On seven separate occasions, an hourly fire watch was not performed within one hour. All events occurred while.both units were in mode I at 100% power.

.The events were: '

'0832. February 15, 1985 Auxiliary Building. Door A183 would not open due to a bad relay and cardreader.

1427 February 28, 1985 TSC. The access door to the TSC will be a keycard door under powerblock. After power _

t .Licantee Events and'Special Reports (Continurd) 85004 At 1511C on February:_15,i1985 with unit 2 in mode _1 at 100% Power, power.was-lost:to protection set I instrumentation. This caused a-reduction in feedwater flow to all steam generators'and loops _one.

N

=

and threeLfeedwater regulator valves to fail closed. The reactor tripped on a lo-lo! steam generator level in loop one. The event-was primarily caused by. personnel error in.that the ASE failed to clearly understand the procedure for removing an inverter from service before

. proceeding.

At 0243C.on February 17, -~ 1985 , - a second reactor trip; occurred due~to

lo-lo level in ! steam generator two. While reducing power because'of an'EHC fluid leak,.the main feed pump tripped because of-low seal-
-injection' pressure _due to condensate feedwater flow fluctuations.

~

2-850'05' With unit 2 in mode '1'at 100% Power at 0118C on: February 12,'1985,

during a' routine inspection of' containment, loose equipment and l-miscellaneous debris was found in the upper compartment.

Special Reports There' were no special' reports transmitted during:the month.

Diesel Generator Failure Report There were no diesel generator failure- reports transmitted during. the month.

SUMMARY

Construction Activities March 1985

ECN L5503, 5111 -Office and Power Stores Facility.

Elev. 710 was transferred.to NUC PR on March 15, with anticipated transfer of Elev.

'694 on April 8. The HVAC system is being balanced at this time. Punch list items and landscaping work remains.

ECN L5609, 5610 - Make-up Water Treatment Plant.

The project is approximately 80% complete. Work on' Phase I is complete and pre-op-tests are being conducted. A FCR has been written to delete the sewage grinder system and to install a septic tank. It is awaiting approval from design.

ECN 5610 yard piping.isLunderway but cannot be completed until pre-op tests are completed.<

The. turbine building piping and the 4" filtered water continues to be worked. (

L ECN L5841- Hot Machine Shop All. work is complete with the exception of the hallway on Elev. 706. This delay is due to power stores and will be completed when they move to their new facility.

Also a mono-rail is to be added in the De-Con Room.

ECN L5599- Fifth Vital Battery.

This project is complete with the exception of the remaining Appendix R work.

The remaining protective. coating will be applied after maintenance is completed in battery rooms I, II, III, & IV.

.ECN L5202-Fifth Diesel Generator Modification.

ERCW discharge-piping is being installed in the yard at the present time.

Pipe installation should be complete by April 8.

-DCR L2108 - Flammable Liquid Storage Building This project is approximately 85% complete. The remaining work consists of:

1. Performed monthly calibration of UHI level switches, SI-196. One switch 1-LS-87-22, was out of tolerance. PRO 1-85-93 was written.

~

2. Westinghouse completed the recalibration of RVLIS instrument racks.
3. The system 30 containment pressure transmitters PDT-30-44 and -45

, were replaced with qualified Barton model 764s. The old transmitters were Foxboro model E11GMs. scaled -1 to 15 psig. The presently installed ,

Bartons~are scaled -1 to 17 psig which required a complete rescaling of the instrument loops and replacement of the scaler on the control room j

~~

indicators. _

4. The commitment to NRC to delete the reset function on the SI block switches was extended to allow the modification to be performed during.

the ice outage.

l 5. NCR SQNNEB 8403 stated that the useful life of the containment H2analyzerb ._

would be limited during a LOCA due to the calayst being poisoned by large concentrations of iodine. To correct this deficiency the vendor supplied j a capsule containing a larger quantity of catalyst. The new catalyst

- capsules were installed in both trains A and B. Subsequent testing revealed that.the diffusion time for gas to pass through the catalyst increased the hold period for each calibration point from five minutes to 45 minutes.

A previous analysis by site services showed that the original catalyst was adequate. The analysis that generated the NCR was based on a large i BWR with higher iodine concentrations than SNP. Train B has been returned i to the original catalyst configuration to reduce out of service time for calibration and functional testing. Train A catalyst will-be returned to its original configuration in the near future.

[

6. The calibration of the new water treatment instruments in system 928 is approximately 90% complete.
  • Unit 2 l

l 1. Performed monthly calibration of UHI level switches, SI-196.2. All switches were within tolerance.

t -2. .The calibration of the RVLIS racks is still in progress. Unit 2 calibration is being handled by Instrument Maintenance.

3. The -system 30 containment pressure transmitters PDT-30-44 and -45 were replaced with qualified Barton model 764s. The old transmitters were Foxboro model E11GMs scaled -1 to 15 psig.
