Dear Kra Grier:
Subject:
Oyster Creek Nuclear Generating Station Docket No. 50-219 Dilution Pump imorovement Program Subsequent to our July 1, 1981 submittal presenting our proposed course of ection to improve the Oyster Creek Station dilution pumps reliability and operabliity, Mr. T. J. Jackson requested further elaboration on the projected schedule by which certain corrective actions may be implemented and an indication of what maintenance j
activities could be conducted in the interim to keep the dilution pumps operable.
As indicated in our original response, the overall dilution' pump system upgrade is scheduled for completion to achieve full compliance by August 1903. The critical path for the e grall upgrade is dependent upon the long lead time required for the replacement parts for the dilution pumps. These items have a projected delivery time of 60 weeks from the date the order is received by the manufacturer. However, it is our objective to complete certain support systems and ancillary work as esriy as November 1982 to achieve reasonable progress toward coropletion of the overalI program by the August 1983 deadline.
The work which we anticipate completing by November 1982 includes the upgrading of the seal water and lube oil cooling water pumps and piping systems, the installation of self-cleaning pipe line strainers and the installation of recesary heat tracing and insulation.
To achieve this objective, purchase orders for the required replaccraer,t equipment are in final preparation and it is projected that the orders for the long lead Items i.e. seal water and lube oil cooling water pumps, line strainers and filters will be processed and placed with the manufacturers no later than September 18, 1981.

i expected delivery times ranging from 15 - 20 weeks for filters, 26 weeks for the pumps and 40 weeks for the strainers.
it should also be noted that upon receipt of the equipment, the actual installation may require scheduling around those periods when wc may be required to have two pumps operatirg, for in some instances the work requireri can on!y be accomplished by having the entire dilution pump system out of service.
Given the projected material order date, delivery dates and installation periods it is believed that we will achieve our November 1982 objective, but it must be recognized that that date could be af f ected by f actors outside our control and therefore it would be inappropriate to specify the November 1982 date as an invariable commitment.
Regarding the dilution pump preventive maintenance program, a source of recent pump outages has been excessive debris buildup at the pump intakes and failure of the dilution pump intake trash racks. The trash racks are routinely checked once per shi f t.
Measures have been taken to have the trash racks checkea and cleaned more frequently as intake conditions warrant. Additional trash racks are on order and wl'.
be available f or replacement as required. However, if replacement is required it will be necessary to take the associated dilution pump out of sevice in order to ef fectuate the repairs.
The station's third dilution pump which was recently undergoing motor repairs has been returned to stand-by status. The station therefore has all three dilution pumps operable and available to meet the two-pump operating requirement.
As previously indicated, we have commited the resources to have the overall dilution pump improvement program completed by August 1983. While every effort will be taken to have the interim repairs completed by November 1982 some f actors which may impact on that date a e out of our control and therefore preclude us from making that a firm commitment date for system Installation.
I hope this response adequately addresses your concerns regarding our July 1, 1981 submittal.
However, should you have any additional questions, please call Mr. Ron Lacey, Manager-Environmental Licensing at (201) 299-2271.
Very truly yours, v
