SUBJECT:
TEAM INSPECTION - NRC INSPECTION REPORT 50-382/98-13
Dear Mr. Dugger:
The purpose of this letter is to announce our medium and low voltage breaker team inspection at your Waterford 3 Steam Electric Station reactor facility. This inspection will be conducted in accordance with Temporary Instruction 2515/137, Revision 1, ";nspection of Medium-Voltage and Low-Voltage Power Circuit Breakers." We have scheduled this inspection for August 31 through September 4,1998. This inspection will involve a team of four NRC personnel.
The inspection will assess medium and low voltage switchgear maintenance activities; refurbishment and lubrica'. ion methods; programs to address NRC generic communications and
{
manufacturers' generic communications; lessons leamed from industry operating experience; q
dedication of commercial grade procured components; your treatment of breakers in the 1
Maintenance Rule program; breaker maintenance history; and breaker reliability.
We request that you arrange a short presentation following the entrance meeting regarding the subject breakers installed at your facility. The inspection team will require information about your program and its implementation for in-office preparation for the inspection. A description of the needed material is in the enclosure to this letter. Our designated team leader (Paul C.
Gage) will be contacting your staff and arranging for some of this specific material to be available to the team by August 19 1998. If you have any questions conceming this inspection, please contact Mr. Gage at 817/860-8273 or me at 817/860-8195.

A listing of all safety-related medium-voltage and low-voltage metal enclosed circuit breakers along with the following information for each breaker:
Original equipment manufacturer l
Type /model number i
Serial number, if assigned (unique identifier, not just shop order number)
Cubicle identification number where currently installed Original equipment supplier (if different from manufacturer) in-service date
=
Date most recent preventive maintenance was performed Date of most recent complete overhaul or refurbishment Breaker functional failures, whether in-service or during testing in last 5 years, if any. Give root cause(s) and corrective actions (s)
Any other corrective maintenance in last 5 years (i.e., to correct unsatisfactory conditions discovered before in-service failure)
Updates, upgrades, or modifications Whether included in the scope of the Maintenance Rule program 2.
Plant procedures for general or corrective maintenance on the breaker (if separate from No. 3 below) 3.
The procedure (s) used to perform routine periodic preventive maintenance (including routine periodic inspection, adjustments, cleaning, lubrication, electrical tests, and diagnostic or predictive testing (e g., timing or reduced control voltage testing, if done), if not specified in procedure, please provide the plant-specified periodicity of preventive maintenance and the document that specifies it or an explanation of how it is specified.
If not specified in procedure, please state any required post-maintenance restoration checks (e.g., post-installation functional check in connect position) and what document requires such checking.
4.
The procedure (s) or specification (s) used for breaker refurbishment, the frequenc> at which this refurbishment is performed, the document or explanation of what specifies the frequency or the conditions requiring refurbishment. Before arrival onsite, we will select
o r l l
refurbishment activities from the list in item 1 (for detailed review after arrival) and will request that associated documentation (e.g., procurement and dedication of parts used in-house, work instructions, and records, etc.) be ready for review. We prefer to review original records and will request copies, as required, unless records are archived and must be printed from microfilm or microfiche.
For the purposes of this inspection, " refurbishment" (or overhaul or remanufacture) means major maintenance that may include the following:
(1)
Complete pre-disassembly inspection and testing (documenting as-found results);
(2)
Complete post-inspection disassembly; (3) inspection of parts for damage or wear, lubricant, proper type, dirt or evidence of other contaminants; (4)

scope of the Maintenance Rule program with the following information:
For any in scope, but non1E breakers, state your scoping basis (e.g., functions important to safety and/or failure modes and effects adverse to sQty).
Describe which breakers are treated as components of the functional plant system whose components the breakers directly supply power to (e.g., load breakers for service water pump motors, battery chargers, etc.).
Describe which breakers are treated as part of the medium, and low-voltage ac, or low-voltage dc electrical distribution systems (e.g., bus feeders, bus ties, transformer feeder, load center switchboard, or motor control center feeders, etc.).
Describe the breakers, if any, for which maintenance or performance issues are treated as a separate class of components across train, system, or unit boundaries (i.e., common mode breaker-related problems affecting more than one train, system, or unit).
List any instances in which breaker functional failures, or breaker-related train or system functional failures, or plant failures / scrams / trips / unplanned shutdowns were attributed.
