Review of Non-Nuclear Instrtimentation (NNI) System Prcblems The inspector examined the buffer amplifier module that had been found to be the cause of the X power buss failure in the NNI system February 26, 1980.
The module consists of a Buffer Connector Board Assembly into which four
'
Voltage Buffer Assemblies can be installed. The Voltage Buffer Assemblies slide on tracks into the connector assembly and connect into the circuits at the rear by means of six slotted pins located on the connector board and six matching pins mounted on the amplifier board. These connecting pins are located such that the makeup, when the amplifier board is inserted, can not be observed. Because the module can contain possibly four different circuits, the entire module can not be removed to observe the pin makeup

during operation without causing the circuits connected through the module to become inoperative. Due to this condition the mismatch of the pins on the amplifier board for the Psat-Tsat modification was not discovered until after the power supplies were lost (February 26, 1980), some eleven days af ter the modification was completed.
The inspector was advised that the same conditions (pin mismatch) was found for the buffer amplifier card installed in the Y powered portion of the NNI system. However, failure had not yet occurred.
In both cases the buffer amplifier card had been installed in the bottom most slot identified as No. 4 in each buffer connector board assembly.
Under close inspection of the Buffer Connector Board Assembly, it was noted that correct pin alignment could not be assured when the buffer amplifier board was installed in the bottom on No. 4 slot. The remaining three other slots were found to be in alignment such that the pins matched correctly.
Discussions with the licensee's technicians and Bailey Meter Company personnel revealed that BMCO has had personnel at the site to review this condition.
During this inspection information was not available regarding the outcome of BMCO's review.
Within the areas examined, no items of noncompliance or deviation were identified.

Procedure Review The licensee has made commitments to the NRC to further divide the X and Y busses in the NNI system to assure adequate instrumentation should the X or Y buss fail. The modifications required are still being reviewed by the FPC engineering staff.
The Compliance Procedure CP-114, Procedure for Preparation and Control of Permanent Modifications, Temporary Modification, Deviations, and Mar Func-tional Test Procedures was reviewed to ascertain that it was adequate to
'
insure that the modifications will be properly inspected, that drawing control is maintained and that the operations section is made aware of the
'
completed modifications in service. Discussions with various supervisory personnel revealed that once a modification is completed, one set of as-built drawings is maintained at the plant until the corporate engineering staff revises the permanent drawings and issues them -, proved. The period of time is not definite. Those~ drawings required by the operators are usually revised in approximately two weeks. The inspector advised the licensee that due to the splitting of the instrumentation between the X and Y busses, the drawings should be made available as soon as possible and training of the operators should be accelerated to insure they will know what instrumen-tation will be available from each buss in case a failure should occur. The Compliance Procedure CP-117, Procedure For Control of Nonconforming Materials was reviewed for the required, approvals, concurrences, dispositions and documentation. During this review it was noted that "all uninstalled equip-
!
ment that is not tagged shall be considered nonconforming and non-safety l

o o-3-related until a review of documentation and physical inspection demonstrates to the contrary". Further, "non-safety related items shall not have Noncon-forming or Information tags attached, as described by this procedure". The inspector stated that care must be exercised to insure that like items that can be used in safety and non safety applications are properly identified.
The licensee advised the inspector that CP-117 will be incorporated into another procedure, CP-111, Procedure For Documenting, The Reporting and Review of Nonconforming Operation, in the near future. The revised procedure will be reviewed to insure that all points related to nonconformances are adequately addressed.
Within the areas examined, no items of noncompliance or deviations were identified.
