SUMMARY
OF MEETING WITH BALTIMORE GAS AND ELECTRIC COMPANY (BGE) ON BGE LICENSE RENEWAL ACTIVITIES On October 16, 1996, the Nuclear Regulatory Commission (NRC) staff met with representatives of BGE in Rockville, Maryland, to discuss BGE's license renewal program for cables. A list of meeting attendees is provided in Attachment 1. Attachment 2 is a copy of the materials distributed during the meeting.
During the meeting, BGE discussed the type, including materials of construction, of cables and environmentally qualified (EQ) equipment installed at Calvert Cliffs. BGE discussed it's aging management evaluation process and identified the potential aging effects that it determined to be plausible.
' The thermal screening process BGE is using for non-EQ equipment and the results of this process was also discussed. BGE discussed it's cable aging management program which will require some cables to be (1) replaced prior to the period of extended operation, (2) subject to a condition monitoring program, (3) partially replaced, with only the portion of the cable replaced that is subject to Harsh Environment when loss of coolant accident (LOCA) survivability not assured, or (4) subject to a performance monitoring program.
For EQ equipment, BGE stated that it would rely on it's current 10 CFR 50.49 program as an aging management program, and would also rely on this program to justify that the current licensing basis (CLB) will be maintained until resolution of generic safety issue (GSI) 168 is resolved.
As a follow on to this meeting, the staff conducted a site visit on November 25, 1996, to review on-site documentation related to BGE's license renewal program for cables. The staff reviewed a number of documents including the cable aging management program summ ry, and fil s.

Safety-related electrical equipment which is required to perfonn an electrical safety function after being subjected to or while exposed to harsh environmental conditions induced by design basis events.
(2) Documentation to substantiate environmental qualification ofin-scope equipment.
An Environmental Qualification Documentation File (EQ File) is maintained for each equipment group. The EQ File contains data on subparts susceptible to environmentally -
induced degradation, the basis of environmental qualification including acceptance criteria, test data, analysis of qualification process and anomalies, etc.
(3) Maintenance and surveillance to maintain qualification on a continuing basis.
Qualification Maintenance Requirement Sheets (QMRS) are maintained for each equipment subgroup. The QMRS identifies installation, maintenance, testing, refurbishment, and monitoring requirements necessary to maintain environmental qualification of EQ equipment.

Life Cycle Management Unit EQ EQUIPMENT THE FOLLOWING EQ ISSUES AFF$CT LICENSE RENEWAL (1) The CLB is to be maintained.
(2) The management of plausible aging must be demonstrated for long-lived equipment with passive functionality.
Long-lived passive device groups include cable, electrical penetrations, seals, terminal blocks, solenoid valves. The cunent EQ Program manages the aging of organic subparts which could adversely affect the required electrical functionality of the EQ equipment.
(3) EQ is considered a TLAA by NRC.
To support conclusion that action will be taken in accordance with the CLB per 10CFR54.29, NRC staff has requested that certain information be provided.
(4) A GSI exists and must be addressed.
The GSI is documented as Issue 168 of NRC Task Action Plan. The SOC to the LR Rule (60FR22484) allows LR applicants to resolve the issue and incorporate resolution in their LRA, orjustify that the CLB will be maintained until reasonable options to manage the aging become available.
