MEETING

SUMMARY

-A Management Meeting was held in the Region II Office on September 12, 1989, to discuss the configuration management program at Farley Nuclear Plant and the results of the licensec's self-initiated safety system assessment (SSSA) of the l

Unit 1 service water system.

The licensee discussed their recently established configuration managemcnt program and presented the results of their SSSA performed on the Unit 1 service water system. The licensee stated that the main problems identified were potential flow balance problems during certain accident scenarios and certain motors (service water pump) that are operating above design temperatures. As a result, these motors will probably have to be replaced within the next two years to ensure that they can perform their safety function under accident conditions.

During this discussion NRC' representatives expressed concerns about the threshold of deportability for potential problems which are identified when conducting SSSAs. The NRC's need for information was discussed and it was pointed out that if further evaluation makes the problem non-reportable, the report can be withdrawn. The licensee understood this concern.

Licensee representatives discussed long term goals of their configuration management program and committed to use this approach to examine 14 systems on a priority basis within the next five years.

m MANAGEMENT PERSPECTIVE p, ]

Generic Issues l

1. Communication weaknesses between designers and plant personnel
2. Inconsistencies in Bechtel and SCS setpoint documents
3. Design change revisions not incorporated into all affected design documents
4. FSAR inconsistencies
5. PM program selection criteria needs to be reevaluated

OFFSITE GENERIC CORRECTIVE ACTION PLANS Short Term (Approximately 12-18 months)

- Review SCS-Mechanical safety related design Conduct mini-SSSA on Component Cooling Water Improve documentation of setpoints Void / supercede outdated unused drawings

- Review FSAR for accuracy and clarity i

I

)

i OFFSITE GENERIC l CORRECTIVE ACTION PLANS Long Term (Considering 3-5 years)

- Evaluated the information needed to support resolution of the issues

- Must compile systems'/ components' functions into more accessible form - Functional System Descriptions (FSDs)

Sequence:

1. Generate FSDs on a system basis
2. Incorporate FSD information into uses

-- Operating procedures PM programs Traim,ng etc.

3. Conduct SSSA on the system Scope:
1. Approximately 14 systems
2. 3-5 years

- Then evaluate what, if any, further actions -

are required

ONSITE CORRECTIVE ACTIONS

1. Short Term (12-18 months)
a. Incorporate new identified system and component functional requirements into plant programs, as identified.
b. Revise procedures to reflect one setpoint document.
c. Review assigned FSAR sections for accuracy and to identify requirements vs. guidelines. Incorporate into procedures as appropriate.
d. Address plant issues from CCW and DG mini-SSSAs.
c. Clearly document the PM criteria and reevaluate safety related equipment against the criteria.

ONSITE CORRECTIVE ACTIONS

2. Long Term (3-5 years)
a. Incorporate system and component functional requirements into plant programs and procedures.
b. . Incorporate FSAR design requirements for plant operation into plant procedures.

Address and document FSAR design guidelines for plant operation.

c. Perform (a.) and (b.) above for the prototype systems. Critique she process and revise as appropriate.
d. Implement corrective actions resulting from the development of the functional requirements.

1

e. Respond to the SSSAs and implement corrective actions resulting from the SSSAs.
