OPERATIONS

SUMMARY

OCTOBER 1992 The plant entered the month of October operating at 100% power producing 860

MWe, It continued full power operation for the entire period and closed the month producing 860 MWe.

MAJOR SAFETY RELATED MAINTENANCE During October, the following major safety related maintenance was performed:

Boric Acid Tank Mixer CA-M-1 Boric Acid Tank Mixer CA-M-1 was removed from service to replace a sheared drive shaft taper pin.

Upon completion of the work, the mixer was satisfactorily tested and returned to service.

Fire Service System Altitude Tank FS-T-1 Altitude Tank FS-T-1 was removed from service in order to accomplish a level switch replacement modification and perform various corrective maintenance tasks.

The corrective maintenance tasks accomplished included: replacement of valves FS-V-83 A/B/C, FS-V-278, FS-V-1007 and FS-V-1226 with ball valves, replacement of recirculation pump FS-P-6,- replacement of valte FS-V-6 with a flanged tee, _ and repair as necessary of the 6" and 12" piping with welded contoured plate. Additionally, heater elements FS-C-1, FS-C-2, and FS-C-3 were replaced, and a new 24 inch ball valve was installed in the heater recirculation piping._ Because of flow restrictions in the Altitude Tank-piping, a contractor was brought on-site to perform high pressure water blasting to clean the 12" discharge pipe, the 6"_ filter water supply pipe,-and the 2)" heater recirculation pipes.

Painting and level switch. calibration continue and the tank is expected to be returned to service in November.

Intermediate Closed Coolina Water Pume IC-P-1A Intermediate Closed Cooling Water Pump IC-P-1A_was taken out of service 1because of noisy motor bearings. The motor and pump' internals were removed and taken to the shop for repairs.

In the shop, a new pump shaft was-fitted and pinned to a new, replacement motor. The pump rotating assembly was installed along with a new mechanical seal. The motor / pump: assembly was reinstalled and after being satisfactorily tested, IC-P-1A was returned to service.

2

Waste Gas System Check Valve WDG-V-41 WDG-V-41, the Waste Gr: Decay Tank inlet check valve was removed from service because of seat leakage.

An inspection of the disassembled valve revealed that the disc was sticking in the bonnet guide. The parts were cleaned and the valve reassembled. WDG-V-41 was returned to service after being satisfactorily tested.

Sample Isolation Valve CA-V-2 Reactor Coolant sample isolation valve CA-V-2 was removed from service because of leakage at the to bonnet-to-body gasket.

The operator air lines-and limit switches were removed and the operator / bonnet assembly was lifted from the valve body to gain access to the gasket seating surfaces. The surfaces were cleaned and a new bonnet gasket was inserted prior to reinstalling and torquing the operator / bonnet assembly.

The operator air-lines and limit switches were reconnected.

CA-V-2 was returned to service after completion of a satisfactorily local leakrate test.

REllILING INFORMATION RE0 VEST 1.

Name of Facility:

Three Mile Island Nuclear Station, Unit 1 P

2.

Scheduled date for next refueling shutdown:

September 17, 1993 (10R) 3.

Scheduled date for restart following current refueling: NA 4.

Will refueling or resumption of operation thereafter require a technical specification change or other license amendment? YES In general, these will be:

a)

Technical Specification Change Request (TSCR) No. 212 requesting'"an increase of the allowable enri:hment of fresh fuel to 5.0 wt/o U was submitted August 25, 1992. The TMI-1 Senior Project Manager-comitted to completir.g approval prior to January 1,_1993.

b)

TSCR No. 220 requesting approval to move the Maximum Allowable LOCA Linear Heat Rate. Limits (T.S. Figure 3.5-2M) to the Core Operating _

Limits Report was submitted on October 29, 1992-c)

Use of gadolinia-urania fuel and B&W Fuel Corporation (BWFC) changes in core physics methods will require change to T.S. 6.9.5.2 which lists approved analytical methods references to support the core Operating Limits Report values.

Changes will include-reference to BAW-10180, Rev. 1, NEMO and BAW-10184P, GDTACO methods (see #6, Item 1,below). Use of the gadolinium integral burnable poison may also require changes to the Reactor Core fuel descriptions in T.S. 5.3.1.

5.

Scheduled date(s) for submitting proposed licensing action and supporting information:

Submittals made to date are described in 4a and b above. -The TSCR-submittal schedule for use of the gadolinia-urania fuel will depend -

on completion of the USNRC review of-the applicable BWFC methods addressed in 4c above. Per recent discussions,_NEMO, Rev. 1-approval is expected prior to January 1, 1993 and the review of GDTACO is expected in May 1993.

B1 sed on these expected approval dates, the GPUN TSCR would be submitted in June 1993.

6.

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:

a)

BWFC and GPUN are now performing tM fuel cycle design for cycle 10, which is scheduled for startup in ber 1993. This design-incorporates reload fuel that cor.

gadolinia-urania.

Use of this type of fuel will require cht

.. to the plant Technical-Specifications as noted in 4c above. These changes will need to be i

supported by approval of BWFC topical reports on reload design l

methods revisions that account for the'Gd effects in the analyses; L

noted in 5 above. To ensure that no delays occur to reload analyses, fuel manufacturing and plant startup schedules, approval of these topicals has been requested for April 1,1993.

b)

TM1-1 will use the new Mark 09 fuel assembly in the Cycle 10 reload

)

batch.

This design is an upgrade of the Mark B8 assetily used in Cycles 8 and 9.

The Mark B9 provides improved fuel thermal limits (LOCA, DNBR, CLM) and repair capabilities. The Mark B9 design meets current BWFC fuel design criteria and has been previously used at other B&W 177 FA plants.

c)

BWFC has several licensing changes under USNRC review. Changes are necessary to upgrade their shipping containers for shipment of fuel up to 5 wt/o U. These changes are necessary to support the TM1-1 Cycle 10 refueling schedule.

Approval of the B&W Model B fuel assembly shipping" container for shipment of single assemblies from 4.6 to 5.1 wt/o U ' is expected in January 1993.

Approval of the SiemensfuelassemblyshippggcontainerfortwoBWFCMarkBfuel assemblies up to 5.0 wt/o U is expected in March 1993.

7.

The number of fuel assemblies (a) in the core, and (b) in the spent fuel storage pool:

(a) 177 (b) 521 8.

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:

The present licensed capacity is 1991.

Phire 1 of the reracking project to increase spent fuel pool storage capacity permits storage of 1496 assemblies. Upon completion of Phar.) 11 i ! the reracking project, the full licensed capacity will b. atteined.

9.

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

Completion of Phase 1 of the reracking project permits full core off-load (177 fuel assemblies) through the end of Cycle 13 and on completion of the rerack project full core off-load is assured through the end of the current operating license and beyond.
