REFERENCE:
~ Letter, S. L. Daltroff, PECo, to D. G. Eisenhut, USNRC, Follow-up Response to Generic Letter 83-28, August 31, 1984
Dear Mr. Thompson:
This-letter provides an update of Philadelphia Electric Company's progress for updating existing Maintenance Procedures and-ensuring that the updated procedures contain the latest vendor information. to this letter specifies the procedures which have been updated and approved by the Plant Operations Review Committee. specifies those Maintenance Procedures which have been deleted but will be retained as E
Special. Procedures or Work Instructions. is the current. schedule for completion of this effort.
Philadelphia Electric Company has contracted the services of a consultant to review and update, as required, all safety-related vendor manuals used at Peach Bottom.
This effort will. result in updating approximately 500 non-NSSS vendor manuals and approximately.250 NSSS vendor manuals.
In order to implement an effective program, the following tasks will be performed:

'Mr. Hugh L. Thompson February 1, 1985 Page 2 Review the " Peach Bottom Atomic Power Station
. Instruction Book Index Numerical Sort" and status of each Vendor Manual filed applicable to Peach Bottom Units 2 and 3.
Identify and analyze modifications performed on the equipment appropriate to each manual using the " Status of Approved Items - Peach Bottom 2 and 3" and available site modification records.
Identify and analyze documenced information, if any, that has been added to.each manual by PECo personnel.
-Contact vendors, where appropriate, to determine where manual revisions have been made, whether supplements or addenda have been' issued, or if existing manuals are applicable.
EstablishJan updated hard-copy Vendor Manual' file with updated index at Peach Bottom and within the Engineering Design ~ Division.
~ Preliminary scoping of the project indicates
'approximately 6 months will be required to update the ma'nuals.
It.may be necessary to.re-evlaunte this schedule with further
. implementation of the program.
The manual update program and the activities regarding the procedure update program will be Ecoordinated.to ensure manuals and procedures are consistent and eliminate duplication of effort in these tasks.
-ShouldLyou require any additional information, please do not hesitate.to contact us..
