OPERATIONS
SUMMARY
The Unit was shut down the entire month by order of the NRC.. Core cooling was provided by the Decay Heat Removal System. The Reactor Coolant System was partially drained during the month to permit continued tube testing and repair work. The secondary side remained in wet layup the entire month.
Major Safety Related Maintenance
~ OTSGs RC-H-1A/B - During the month of January,1985. Eddy Current Testing was completed. The "A" OTSG test results shcwed 297 tubes with greater than 40%
thru-wall defects, and 93 tubes with greater than 70% thru-wall defects. The "B" OTSG test results showed 33 tubes with greater than 40% thru-wall defects, and 5 tubes with greater than 70% thru-wall defects. The "A" OTSG upper tubes requiring stabilization (40 tubes) were endmilled, stabilized and plugged with B&W nail head weld plugs. Preparations are in progress to stabilize and plug 5 tubes in the "B" 0TSG upper tube sheet. This work will be completed in February, 1985. Preparations are_in progress to install B&W roll plugs in the A&B upper tube sheets, and B&W mechanical ribbed plugs in the lower tube sheets, on the tubes to be plugged (greater than 70% thru-wall defects).
INTERMEDIATE CLOSED COOLING WATER COOLER IC-C-1A - Cooler IC-C-1A work was completed in January including sandblasting the tube sheets and applying of Belzona compound. The water boxes were coated with coal tar epoxy and magnesium anodes were installed. The cooler was flushed, fitted with new gaskets, and the end covers reinstalled. All work has been completed.
NUCLEAR SERVICES CLOSED COOLING PUMP NS-P-1B - NS-P-1B was disassembled from the casing and individual components removed due to failure of tF2 bearing. _
The pump shaft bearing surface was measured and repaired by metal spray welding. Reassembly is expected to be completed during February,1985.
AIR HANDLING SYSTEM PURGE VALVES AH-V-1A/B/C/D - Work commenced on valve AH-V-1D to replace the rubber seats. The seat retaining screws / segments were removed and cleaned and the old seats were removed from the valve.
Preparation for cutting and installing new seats is in progress and work is expected to be completed during February,1985.
EMERGENCY FEEDWATER PUMP EF-P EF-P-1 bearing failure repairs started in January, 1985. The outboard bearing assembly was removed, cleaned, and inspected. A new bearing was installed with Locktite, and the bearing assembly was reinstalled. Thrust measurements were taken, coupling was aligned and the pump was test run satisfactorily. The bearing drain line was.
cleared and will be modified in February,'1985 to prevent shaft immersion.
This work was reported on Nuclear Network as Item OM #2408.

4 REFUELING INFORMATION REQUEST 1.
Name of Facility:
Three Mile Island Nuclear Station, Unit 1 2.
Scheduled date for next refueling shutdown:
Unknown 3.
Scheduled date for restart following refueling:
Unknown h.
Will refueling or resumption of operation thereafter require a technical specification change or other license amendment?
-If answer is yes, in general, what will these be?
If answer is no, has the reload fuel design and core configuration been reviewed by your Plant Safety Review Committee to determine whether any unreviewed safety questions are associated with the core reload (Ref. 10 CFR Section 50.59)?
If no such review has taken place, when is it scheduled?
Amenument No. 50, Cycle 5 reload, was approved on 3-16-79 5
Scheduled date(s) for submitting proposed licensing action and supporting information:
N/A 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:
N/A 7
The number of fuel assemblies (a) in the core, and (b) in the opent fuel storage pool:
(a) 177 (b) 208 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 752. There are no planned increases at this time.
9 The projected date of the last refueling that can be discharged to the spent-
-fuel pool assuming the present licensed capacity:
1988 is the last refueling discharge which allows full core off-load capacity (1TT. fuel assemblies).
