MONTHLY OPERATING REPORT FEBRUARY 1989 The following Licensee Event Reports were submitted during the month of February 1989:
LER 88-001:
POSSIBLE LOSS OF MAIN STEAM LINE ISOLATION CAPABILITY DUE TO EXCESSIVE MAIN STEAM ISOLATION VALVE CONTROL AIR LEAXAGE
)
i In response to NRC Generic Letter 88-14, " Instrument Air Supply System Problems Affecting Safety-Related Equipment",. and concerns identified during the E0P inspection and internal review of the air system, testing was performed on the Main Steam Isolation Valve (MSIV) control air system on January 3,1989. The purpose of the testing was to check the MSIV accumulators for water and to test control air check valve leak tightness.
The testing plan could not be completed due to excessive air leakage from control air piping connections.
This condition was determined reportable on January 11, 1989. The MSIV control air system leakage is attributed to the system construction.
The MSIV control air piping is made from threaded brass pipe assemblies which are prone to leakage due to the material used, method of assembly, and maintenance performed on the system over the life of the plant.
This condition could have prevented the fulfillment of the safety function of reactor and/or primary containment isolation in the event of an accident condition. Corrective actions include replacing the control air system piping with stainless steel pipe to eliminate leakage. Corrective actions to address MSIV leakage are being evaluated and will be submitted in a followup LER.
In addition, future testing of air accumulators and related piping will be performed in accordance with the testing program developed by GPUN in response i
This event is reportable based on 10CFR50.73(a)(2)(v)(C&D).
LER: 89-002:
POSSIBLE FUEL POOL GATE MOVEMENT AB0VE IRRADIATED FUEL This is a voluntary report to document an occurrence at the site.
This event has been determined to be not reportable, however, this report does contain information of interest to the industry.
On January 14 and 15,1989, a Fuel Pool Gate (FPG) may have been moved over irradiated fuel stored in the fuel pool.
Technical Specifications state that no object in excess of the weight of one fuel assembly may be moved over stored irradiated fuel. Although no one could state conclusively that this did occur, observation of one of the moves by a licensed Control Room Operator (CRO) and post event analysis indicate that this may have occurred. 'The cause of this incident is personnel error. The contractor maintenance personnel moving the FPG failed to adequately monitor the gate's movement to ensure it did not pass over the irradiated fuel.
Water being sprayed on the gate to prevent airborne contamination also restricted the contractor personnel's ability to observe the gate location in relation to the fuel.
Personnel were not required by procedure to specifically monitor the path of the FPG movement. Corrective action included relocating spent fuel to provide additional clearance for any path that the gates may have to transverse, and assignment of a monitor specifically charged with monitoring any fuel pool gate movements to preclude recurrence.
This requirement will be incorporated into the fuel pool gate movement procedure.

Important -licensing considerations associated with-~ refueling, e.g.,
new or different fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procedures:
j
- 1. General Electric Fuel Assemblies - fuel design and performance analysis rathods have been approved.by the NRC.

- 2. Exxon Fuel Assemblies - no major changes have been made nor are l
there any anticipated.

= 1595 (c) in dry storage 16
=
The present licensed spent fuel pool storage capacity and the size of any increase in licensed storage capacity that has been requested or is planned, in number of fuel assemblies:
Present licensed capacity: 2600
- The projected date' of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity:
Reracking of the fuel pool 'is in progress.
Nine (9) out of ten (10) racks have been installed to date.
When reracking is completed, discharge capacity to the spent fuel pool will be available until 1994 refueling outage.
