Work Control Procedures a.
Operations The work control procedures require that a Work Request Authorization ("WRA") be issued for all work to be performed in the plant. The work is not to commence until the WRA is signed by the Shift : vervisor. There have been only minor
,
changes in this procedure in the last 12 months. The inspec-tor commented that this procedure should provide better control (
of work on penetration seals using the penetration seal control procedure, b.
Ignition Sources The licensee has developed and issued a procedure (Welding Permit) to provide control of ignition sources that are to be used in the plant. The smoke detector used in seal repair is a " smoke gun" (Tel Tru) which is a low temperature smoke generator.
c.
Fire Watch The need for a fire watch is called out on the welding permit.
The fire watch training by the licensee is covered under other areas and functions. The inspector questioned the adequacy of the training of contreetor and offsite personnel as the present method appeared to be somewhat weak. The licensee agreed to revizw procedures on this item and correct any weaknesses noted.

Surveillance (Quality Assurance).
The verification that the operations personnel have authorized all WRA's to commence, is performed as part of the overall pro-gram. This verification is to be performed on the active WRA
'
form file. The above review also confirmed that the work package is completa as stated on the controlling WRA form. This includes the welding authorization and the firewatch if required. The adequacy of the firewatch and the required conditions in order to commence the job are the work foreman's responsibilities.
No iters of noncompliance or deviations were identified during the inspection of this area.
4.
Design Change - Controls The controls on the design changes to provide assurance that the penetration seals are maintained in an acceptable condition was found to be covered by procedures. The majority of the control is provided by the WRA procedure. A WRA form must be issued to authorize the work required by the design change to be performed I
within the plant.
The facility has issued a procedure for control and repair of penetration seals that has been distributed. The procedure provides for the material used, the verification of repair and the control of open penetrations.
No items of noncompliance or deviations were identified during the inspection of this area.

A fire fighting drill was held as required and several items were identified in the critique and corrected. With the revised security at the facility, special procedures were required for various emergencies.
b.
Alternate Procedures The alternate sources of coolant and methods for accomplishing an orderly shutdown and cooldown are described in procedures.
The coolant sources are listed in order of performance and the system procedures contain the lineups and methods to provide the alternate coolant supply to the vessel. The alternate procedure for shutdown and cooldown provide the method, place of use, and equipment necessary to perform the task.
No items of noncompliance or deviations were identified during the inspection of this area.

Facility Inspection a.
Insurance Inspection The fire inspections are performed by a third party, an inspec-tor connected with the facility's insuror. A consultant was retained by the licensee to perform an evaluation of the fire
{

The results and commit-ments were forwarded to DOR in letters dated December 10, 1976; March 11, 1977 and July 5, 1977.
b.
Plant Tour The general housekeeping in the plant was satisfactory, with the exception of two relatively small areas. The licensee corrected these discrepancies. The installed fire protection and detection equipment surveillance was noted to have been performed per procedures. The electric fire pump has been used to maintain fire main pressure during the period that the fire main jockey pump is operable.
