SUMMARY

March 1986 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.

The units remained in an administrative shutdown the entire month due to design control review, configuration control updating and resolution of significant employee concerns.

Outage related maintenance and modifications are being performed.

Unit I has been off-line 221 days.

l Unit 2 has been off-line 222 days.

SIGNIFICANT OPERATIONAL EVENTS Unit 1 Date Time Event 03/01/86 0001C The reactor was in mode #5.

The administrative shutdown due to design control review, confi-guration control updating and resolution of significant employee concerns continues.

l FUEL PERFORMANCE Unit 1 The core average fuel exposure accumulated during March was 0 MWD /MTU with the total accumulated core average fuel exposure of 0 MWD /MTU.

Unit 2 The core average fuel exposure accumulated during March was 0 MWD /MTU with the total accumulated core average fuel exposure of 8097.51 MWD /MTU.

There was no fuel movement within the reactor. However, two additional shipments of cycle 4 new fuel (24 bundles) were received during the month.

The final shipment of new fuel is tentatively scheduled to be received j

April 15, 1986. All new fuel is presently stored in the new fuel storage vault.

SPENT FUEL PIT STORAGE CAPABILITIES The total storage capability in the spent fuel pit (SFP) is 1,386.

However, there are five cell locations which are incapable of storing spent fuel. Four locations (A10, All, A24, A25,) are unavailable due to a suction strainer conflict and one location (A16) is unavailable due'to an instrumentation con-flict. Presently, there is a total of 348 spent fuel bundles stored in the q

SFP. Thus, the remaining storage capacity is 1,033.

1 PORVs AND SAFETY VALVES

SUMMARY

No PORVs or safety valves were challenged in March 1986.

LICENSEE EVENT REPORTS The following licensee event reports (LERs) were reported to the Nuclear Regulatory Commission in March 1986.

LER Description of Event 1-86002 At 0002 CST, February 12, 1986, a main control room-isolation (MCRI) occurred during the performance of surveillance i

instruction (SI) - 197, " Periodic Calibration of Control Building Heating, Ventilation, and Air Conditioning System".

Personnel error due to improper preplanning was the root cause of this j

occurrence.

1-86003 An auxiliary building isolation (ABI) occurred at 0935 CST, February 20, 1986, while performing surveillance instruction (SI) - 501, "120 VAC Perferred-Inverters," when the wrong breaker on the distribution panel was tripped. This action caused the loss of power to 0-RM-90-101 which initiated the event. The error was caused by personnel not following procedure.

2 e

LICENSEE EVENT REPORTS (continued) 1-86004 The floor drain collector tank was not conspicuously barricaded as a high radiation area and thus personnel enter the area without complying with the RWP requirements and got their clothing contaminated which could not be decontaminated.

This occurrence was discovered January 11, 1986, and was caused by two personnel errors.

First, the rope barricade was inadequate and second, personnel failed to follow RWP requirements.

1-86005 On three separate occasions, fire watch personnel were unable to comply with the action statement of technical specification 3.7.12.

A fire watch was not initiated on one occasion when a breaching permit was written.

Two of the first three occurrences were caused by the fire door being jammed shut causing the door to be inoperable.

The third event was caused when a screw broke in the handle release mechanism making the door inoperable.

SPECIAL REPORTS The following special report was submitted to the NRC in March 1986.

Report #

Description 86-01 Fire door C46A was discovered inoperable during the performance of surveillance instruction (SI) - 701,

" Visual Inspection of Fire Doors." This event occurred at 1400 CST, January 27, 1986. Door C46A is the roll up door outside the shift engineer's office in the control building on elevation 732. A breaching permit was issued to establish a fire watch per technical specification 3.7.12.

It also provides administrative control to return the door to functional status within seven days as required by technical specifications. The permit was not closed within the required time, thus requiring a special report.

OFFSITE DOSE CALCULATION MANUAL CHANGES No changes were made to the Sequoyah Offsite Dose Calculation Manual during the month.

MAINTENANCE SMDIARY (INSTRMENTATION) 1 1

INSTRUMENT MAINTENANCE MONTHLY REPORT ITEM FOR MARCH 1986 UNIT 1 Workplan 11726 was field completed.

This workplan performed post maintenance test on the rod control system after the field cable connectors were hand wired.

Work was begun on WP-11712 to replace steam flow transmitters (ECN-6347). Approx-imately 90% of the work was completed during the month of March.

During a technical Specification review for unit operability, it was discovered that all the bistable setpoints listed in SI-202 (IMI-63) for containment sump switchovers from RWST were set out of the technical specification limits. All four loops, L-63-176, -177, -178, and -179, are affected.

PRO-1-86-060 was initiated and the procedure will be revised.

The setpoints were incorrect due to a change in the sensor bellows elevation shown on TVA drawings, and the elevation in technical specifications was not changed accordingly.

Workplan 11762 was completed.

This workplan conducted the post maintenance test for the auto shunt trip modification a test deficiency exists concerning plant wiring which is being cleared by electrical modifications.

Completed workplan 11916 which changed the setpoints on numerous fenival switches.

The function of these switches is to isolate steam to the terry turbine and to isolate steam from the auxiliary boiler in the event of a steam line break. This was a 10CFR50.49 required maintenance item.

PRO 1-86-045 was initiated because of the failure to test the initiation of a reactor trip from the manual SI hand switch.

This is a technical specification surveillance requirement and must be tested every 18 months. An LER has been issued based on this PRO.

UNIT 2 Workplan 11791 was field completed.

This workplan performed post maintenance test on the rod control system after the field cable connectors were hand wired.

Pressurizer level transmitter 2-LT-68-320 was rescaled af ter the transmitter was relocated to outside the crane wall.

During a technical specification review for unit operability, it was discovered that all the bistable setpoints listed in SI-202 (IMI-63) for containment sump switchover from RWST were set out of the technical specification limits. All four loops L-63-176, -177, -178, and -179, are affected. PRO 1-86-060 was initiated and the procedure will be revised.

The setpoints were incorrect due to a change in the sensor bellows elevation shown on TVA drawings, and the elevation in technical specifications was not changed accordingly.

Workplan 11890 was completed. This workplan conducted the post maintenance test for the auto shunt trip modification. A test deficiency exists concerning plant wiring which is being cleared by electrical modifications.

PRO 1-86-045 was initiated because of the failure to test the initiation of a reactor trip from the manual SI hand switch.

This is a technical specification surveillance requirement and must be tested every 18 months. An LER has been issued based on the PRO.
