subject: TI 126 l 1
In today's meeting we developed a series of questions / checklist (see attached file) to record our reviews. We used this to document our review of the first 8 Region III plants. Please use it to record your reviews of the remainder of
, the Region III submittals (Duane Arnold, Fermi, Kewaunee, LaSalle, Monticello, l
Palisades, Perry, Point Beach, Prairie Island, Quad Cities, and Zion) and be l prepared to discuss them in our meeting Monday afternoon. Have a nice weekend.

! . l P.S. We agreed to address specific strengths, weaknesses, and give an overall l assessment of each plant / submittal after a complete review of all submittals. ,
l Keep this in mind when performing your reviews. !

NRR TI 2515/126 SUBMITTAL REVIEW PLANT:
- 1. Does the licensee PERFORM on-line preventive maintenance? (consider frequency and trending information) l
- 2. Does the licensee PLAN and CONTROL on-line PM activities? (consider
, schedule adjustments to account for degraded or inoperable equipment) 2
- 3. Does the licensee have in place formal PROCEDURES to schedule and control on-line PM7 !
i
- 4. Does the licensee incorporate PRA insights?
l
- 5. Does the licensee use sophisticated QUANTITATIVE or simple QUALITATIVE risk models?
- 6. Does the licensee consider the risk significance of maintenance activities on both safety-related and NON SAFETY-RELATED EQUIPMENT?
I
- 7. Does the licensee consider the operability and reliability of REDUNDANT ,
SYSTEMS / MULTIPLE TRAINS?
- 8. Does the licensee MONITOR out-of-service (00S) time?
- 9. Does the 00S include all potential UNAVAILABILITIES? (i.e. surveillances, corrective maintenance, etc.)
- 10. Are licensee personnel KNOWLEDGABLE and TRAINED? (consider both a basic knowledge of scheduling and maintenance activities as well as detailed PRA/IPE understanding)
ADDITIONAL COMENTS:
The OBJECTIVE of TI 2515/126-01 is to evaluate the impact on safety of licensee's procedures and practices regarding the removal of equipment from service for on-line scheduled maintenance. Keep this in mind when addressing the following:
To what extent (FREQUENCY) does the licensee perform on-line maintenance? ,
Does the licensee have in place adequate PROCEDURES to schedule and control on-line maintenance?
Does the licensee consider the CUMULATIVE IMPACT of the maintenance activities on overall plant safety? l Are the licensee's supervisory and working PERSONNEL KNOWLEDGEABLE of the process for planning, scheduling, and performing operations and maintenance activities? )
^
Does the licensee attempt to INTEGRATE scheduled maintenance activities with EXISTING DEGRADED OR IN0PERABLE EQUIPMENT?
4 Does the licensee consider each of the THREE QUALITATIVE RISK FACTORS (initiating events, accident mitigation, and containment integrity) when planning and scheduling maintenance activities?
How do they accomplish this (i.e. computer models, matrices, etc.)? l i
Does the licensee use QUANTITATIVE (i.e. PRA) MEASURES to determine risk significance prior to on-line maintenance?
Does the licensee consider the confidence in the operability of REDUNDANT / DIVERSE EQUIPMENT when planning maintenance activities?
Does the licensee allow MULTIPLE TRAIN OUTAGES?
Does the licensee MODIFY MAINTENANCE SCHEDULES to account for degraded or inoperable equipment? j How does the licensee determine the MAXIMUM OUTAGE TIME for planned maintenance activities?
~
I Does the licensee meet the intent of the MAINTENANCE RULE?
Do they balance the improvement in reliability resulting from maintenance with the increase in equipment unavailability?
4 Do they evaluate the impact on safety of all equipment currently out of service prior to taking additional equipment out?
Does the licensee consider the risk significance of maintenance activities on both safety-related and NON SAFETY-RELATED EQUIPMENT?
4 Does the licensee's on-line SCHEDULED MAINTENANCE FOR THE UPCOMING CYCLE identify 1
instances where planaed maintenance activities could potentially have an impact on overall plant risk?
What is your OVERALL ASSESSMENT of the licensee's on-line maintenance program?
