MONTHLY OPERATIONS REPORT APRIL 1983 4
The defueling of the reactor core was completed and a total of four (4)
LPRMs were replaced during the report period.
A fifth LPRM (LPRM 20-49) was removed from the core; however, in an attempt to install the new LPRM in the core, interference problems developed.
Subsequently, a temporary plug was installed in LPRM 20-49 until the interference problem is resolved.
Stan&y Gas Treatment System (SGTS) II was declared inoperable on April 18, 1983 after it failed its operability test on high HEPA filter diffarential pressure.
The prefilter and HEPA filters were replaced.
Upon ratesting the system, it again failed the operability test.
This time, it was due to a strip heater failure problem.
When resolved, the system will not 'be operable until a HEPA filter efficiency test can be perfarmed.
Additionally, the following events were considered noteworthy:
i 1
The plant is experiencing problems with the tripping of both new augmented fuel Pool Cooling Pumps.
Monitoring equipment has been installed to evaluate the problem.
2 Maintenance was completed on. the Stack Gas Sample System flow control valve.
The flow control valve became inoperable in the closed position for approximately 10 minutes on April 20, 1983.
3 A bomb threat (Unusual Event) on April 22, 1983 stopped all work in the Reactor Building on the day shift for approximately six %)
hours.
A second bomb threat (Unusual Event) on April 27 stopped all work in the Reactor Building on the day shift for approximately two (2) hours.

...'n-Oyster Creek Station #1 Docket No. 50-219 REFUELING INFORMATION - APRIL,1983 Name of Facility:
Oyster Creek Station #1 Scheduled date for next refueling shutdowr.: Presently shutdown for Refueling Scheduled date for restart following refueling: January 12, 1984 Will refueling or resumption of operation thereafter require a Technicai 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 forma 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.g., new or different 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 made nor are there any anticipated.
The number of fuel assemblies (a) in the core 0
(b) in the spent fuel storage pool - 1341 The present licensed spent fuel pool storage capacity and the si::e of any increase in licensed storage capacity that has been requested or is planned, in number of fuel assemblies:
Present: 1,800 Planned: 2,600 The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity:
The Spring 1987 Outage.*
- NOTE: This is for a normal refueling. Full core off-load, however, can only by accommodated through about 1983 or 1984 with 1800 licensed locations.
