OPERATIONS March 1983 At the beginning of the report period, the OC Station was shutdown for the 1983 Refueling / Maintenance outage.

The inspection of the Core Spray Sparger and Annulus and the preliminary

(" quick-look") inspection of the Reactor recirculation piping was completed.

Defueling of the Reactor core was started; however, during the latter part of the month, various problems with the refueling grapple were experienced. At the end of the report period, maintenance activities were in progress to repair the grapple. A total of 462 fuel assemblies (82.5%) have bee.n removed f rom the Reactor core.

Standby Cas Treatment System II was temporarily declared inoperable (one day) due to a failed flow sensing line.

Additionally, the following events were considered noteworthy:

1.

The mechnical seals on Fuel Pool Pumps "A" and "B" were replaced.

The Augmented Spent Fuel Pool Cooling System was placed in service.

2.

The "A" and "B" Feedwater strings were drained for pump and valve maint enanc e.

3.

The processing of the Torus water and flush of the Core Spray and Containment Spray Systems was completed.

4.

A tube leak on "A" Fuel Pool Heat Exchanger was identified and is being repa ired.

The following Licensee Event Reports were submitted during March 1983:

Reportable Occurrence No. 50-219/83-02/03L: Bank 5 (Startup Transformer A) was taken out of service to allow investigation of an electrical fault on the dilution plant power feed.

Reportable Occurrence No. 50-219/83-05/03L: Containment Spray System high drywell pressure switches IP15A, IP15B, and IP15C tripped at a value greater than that specified in the Technical Specifications.

Reportable Occurrence No. 50-219/83-06/03L: The low flow switch for Standby Gas Treatment System II exhaust fan 1-9 failed to sense a low flow condition thereby preventing System II isolation valves from closing.

Reportable Occurrence No. 50-219/83-09/ 0lT: The results of local leak rate testing identified that Main Steam Isolation Valves (MSIV) NSO4A and NSO4B failed to meet acceptance criteria.

Reportable Occurrence No. 50-219/83-12 /0lP:

Secondary Containment int egrity was violated when the door to the Main Steam Line Tunnel Room was lef t open.

Reportable Occurrence No. 50-219/83-11/03L: The low flow switch for Standby Gas Treatment System II exhaust fan 1-9 failed to sense flow in System II causing the isolation valves to close.

Reportable Occurrence No. 50-219/82-53 /03L-1: While operating with one idle recirculation loop a second recirculation pump tripped and was idle for three minutes.

Reportable Occurrence No. 50-219/83-13 /0lP: A degradation of Secondary Containment Integrity occurred when both doors of a Reactor Building personnel access airlock were open simultaneously for approximately 30 seconds.

Oyster Creek Station !l Docket No. 50-219 i

REFUELING INFORMATION - MARCH 1983 Name of Facility:

Oyster Creek Station !!

Scheduled date for next refueling shutdown: Presently shutdown for Refueling Scheduled date for restart following refueling:

January 12, 1984 Vill refueling or resumption of operation thereafter require a Technical Specification change or other license amendment?

Technical Specification Change Request No. 96 was submitted on August 31, 1982 for incorporation of GE fuel assemblies into the Cycle 10 core.

Scheduled date(s) for submitting proposed licensing action and supporting in fo rma t ion:

June 1,1983 - The final supplement to the reload analysis, delineating the specific core configuration for Cycle 10 operation, will be submitted.

Important licensing considerations associated with refueling, e.f., new or d i f fe re'n t fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procedures:

1.

General Electric fuel assemblies - fuel design and performance analysis methods have been approved by the NRC. New operating procedures, if necessary, will be submitted at a later date.

2.

Exxon Fuel Assemblies - No major changes have been cade nor are there any anticipated.

The number of fuel assemblies (a) in the core 98 (b) in the spent fuel storage pool 1243 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 assembiles:

Present: 1,800 Planned: 2,600 l

The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity:

l The Spring 1987 Outage.*

  • NOTE: This is for a normal refueling.

Full core off-load, however, can only be acco=modated through about 1983 or 1984 with 1800 licensed locations.
