50-249/79-06)
Areas Inspected: Routine, unannounced inspection of fire prevention /
protection of work control procedures, quality assurance surveillance, design change controls, emergency procedures and facility inspection.
The inspection involved 22 inspector-hours onsite by one NRC inspectcr.
Results:
Of the five areas inspected, no apparent items of noncom-pliance or deviations were identified in three areas; one apparent item of noncoupliance (infraction - failure to conduct fire brigade training sessions quarterly - Paragraph 2) was identified in one area; one apparent item of deviation (failure to develop a procedure for control of combustibles) was identified in one area.

Work Control Procedures Work control procedures were reviewed for operations personnel approval and control of all construction, modification and main-tenance activities for special authorization of activities involving welding, open flames, ignition sources, and firewatch.
Work involving welding, cutting, or grinding is documented on the welding and cutting permit and reviewed for fire hazards by responsible personnel.
A review of fire briga6e training procedures and program was cor-ducted to ensure that specific provisions included in the work control procedures are implemented by properly trained personnel.
The technical specification amendments on fire protection became effective on May 1, 1978, which included a requirement for quarterly Jire brigade training sessions. Although the licensee met this requirement for the first quarter of 1979, a quarterly fire brigade training program for 1978 was not implemented.
Training was given during the third quarter on fire extinguishers, but training was not conducted for the second and fourth quarters of 1978.
Prior to the conclusion of the inspection, the inspector verified that a training program for fire brigade members had been developed for 1979 to prevent recurrence.
It is the inspector's concern that this item had substantial potential to reduce the licensee's ability to establish and maintain the capability to fight potential fires.
This finding represents noncompliance with the requirement that fire brigade training sessions shall be held at least quarterly under Tech-nical Specification G.l.E.

3.
Quality Assurance Surveillance An inspection was conducted to determine if the quality assurance program performed periodic audits to verify that the controlling procedures were in use.
Work procedures were reviewed by quality assurance to insure cable penetration seals were reinstalled or replaced when removed.
The inspector reviewed off-site Quality Assurance Audit II-78(12)
of fire protection conducted on October 3-4, 1978.
It was pointed out to the licensee that these annual audits are to provide an overall assessment of conformance to fire protection requirements (i.e., fire protection technical specifications and approved procedures covering fire protection program implementation).
No items of noncompliance or deviations were identified.
4.
Design Change Contrnls Plant modifications are implemented by a work request and completed in accordance with the design of the plant modification program as outlined in Dresden Administrative Procedure, DAP 5-1.
Fire stop seal material replacements are verified to be as specified by Dresden Fire Prevention Procedure, DFPP 4175-1.
No items of concompliance or deviations were identified.
5.
Emergency Procedures The inspector verified that emergency procedures for fire fighting in vital areas contained special instructions for the fire brigade and alternate methods for acet_plishing an orderly plant shutdown.
The facility's guidelines for scheduling of fire drills are to have monthly unannounced drills. Review of the records indicated the fire drills were performed and critiqued as required.
No items of noncompliance or deviations were identified.
6.
Facility Inscection a.
Fire Inspections The facility fire inspections are performed by NML insurance personnel. The recommendations are reviewed for corrective-3-43b5 019
action and a schedule of open items maintained for resolution.
A review of the surveillance documentation indicated that flow tests of fire protection water were performed successfully.
Tour The inspec6cr toured the plant to observe housekeeping, equipment, wiring centrols, etc. required for fire pre-vention/ protection and fire fighting.
Four potet*4
fire bazards were identified:
(1) Untreated wood is used in vital and safety related operating areas of the plant. This has been previously identified by NML and NRC a number of times.
During the Region III report 78-02 management interview, the licensee stated that a more comprehensive schedule of flammable naterial control would be provided for various areas of the facility; and followed up with AIR 12-78-15 specifically addressing untreated wood. As of this date, the licensee has not developed a procedure for control of combustibles. Dresden Administrative Procedure, DAP 7-12, Plant Clear.licess Inspection Program, is unsatisf actory.
Provisions for proper control are given in Appendix A to BTP 9.5-1, Attachment 3, Paragraph (e), requiring in part that al; wood used in safety related areas shall be con-trolled to assare that it is treated wi;h flame retardant.
The lic-usee is committed to this guide and it is an accepteu practice in the industry.
It is the inspector's concern that this item, transient fire loads, has substantial potential to cause the total fire load to exceed the capabilities of existing suppression systems and squipment. This finding constitutes an item of deviation from the commitments made to BTP 9.5-1 in licensee responses dated August 1, 1977, January 24, 1978 and March 20, 1978.
(2) A number of prohibited items were found in safety related areas (i.e., juice can, candy and gum wrappers and con-taminated cigarette butts).
(3) Oily rags and garbage on the floor of the crib houses
-
represented poor housekeeping.
(4) Units 2 and 3 cable trench was flooded with mud and water from seepage due to spring melting.
