, The NRC inspector toured the reactor building, control room, and

!- auxiliary buildings to observe construction in progress and to inspect housekeeping.

l No violations or deviations were identifie .- 0A Programs and Procedures - Instrumentation Components and Electric Cable Systems The purpose of this inspection was to determine'whether appropriate and adequate procedures exist to ensure-compliance with-NRC requirements and J

licensee commitments for.the performance.of the following activities pertaining to instrumentation components and electrical cable systems:.

work, construction testing, personnel qualification, and change control.

4 Work Procedures

,

The NRC inspector examined the. licensee's QA procedures for work  !

pertaining to instrumentation and electric cable installations. The procedures examined'and the licensee's adherence to these procedures dppeared to meet NRC requirements and licensee commitments. The i procedures examined are listed below:

In the areas reviewed, the procedures provided instructions designed to assure that:

(1) Instrument components- (type, range, accuracy, material, etc.)

were identified, located, oriented, and supported as specified;-

(2) Physical separation and independence requirements of redundant components were met; (3) Special handling, installation, and maintenance requirements, including those pertaining to protection, preservation of internal cleanliness, and maintenance of component qualification requirements, were met; l (4) Cables were identified, routed, and supported as specified; and

(5) Cable type and size, sepa' ration, and hold points were me No violations or deviations were' identified.

The NRC inspector examined the licensee's QA procedures for qualification, certification, and training of quality control and craft personnel. The procedures examined and the licensee's

'

adherence to these procedures appeared to meet NRC requirements and licensee connitments. The procedures examined are listed below:

Indoctrination, Training, and Qualification of Quality Control Personnel - QCP-2.1, Revision 6, dated February 7,198 QAl-020, Attachment 1, NDE-1, Training Examination and Certification of Nondestructive Examination Personne *

Ebasco Quality Assurance Manua In the areas reviewed, the procedures provided instructions designed to assure that:

(1) Installation equipment was being used properly; (2) Cables were being handled properly and adequate protection is provided; (3) Requirements for the installation of safety-related cables were identified; and (4) Approved methods were used for cable terminations, splices, and cable ends protection.

e No violations or deviations were identified.

-5- Change Control Procedures The NRC inspector reviewed the licensee's QA procedures for the control of drawings during the installation of safety-related instrumentation and electric cable systems. The procedures examined are listed below:

Field Change Requests - SSP-49, Revision 1, dated February 2, 1987.

,

Field Change Notice - ASP-7, Revision 7, dated June 25. 198 Field Fabrication Mo'difications - ASP-22, Revision 4, dated May 29, 198 EE580 Electrical Installation - CSP-40, Revision 5, dated November 3, 198 *

Electrical Separation - SSP-45, Revision 3, dated September 4, 198 In the areas reviewed, the procedure ensured that:

(1) Design and construction organizatio'ns were coordinated; (2) Retrieval of-voided drawings and specifications at work sites was controlled; (3) Periodic inspection of drawings, specifications, and procedures used in the field was accomplished; and (4) Field changes were subject to adequate design control and were incorporated into the as-built records.

No violations or deviations were identifie . Closure of Significant Construction Deficiencies

, (Closed) SCD No.153 ECW System Pump Instrumentatio On July 18, 1983, pursuant to 10 CFR 50.55(e), HL&P notified the NRC of an item concerning instrumentation associated with the ECW system pumps. The potential existed that under a loss of offsite power or loss of instrument air the level switches in each ECW pump cubicle could generate a false low water level signal. This signal, in turn, l would trip all of the ECW pumps. The ECW pumps cannot be restarted unless a safety-injection (SI) signal is initiated. The primary function of the level instrumentation is for pump protection. The corrective action was to delete the automatic pump trip function from the low-level ECW pump cubicle well instrumentation. The logic

diagram SR289Z42077 and flow diagrams SR289F05038 and 5R289F05039, were revised to reflect.this change. The NRC inspector verified that the referenced drawings had been revised to reflect this chang This item is considered closed.

(Closed) SCD No. 53 Diesel Generator Fuel Oil Tank Room Exhaust Fan During a routine design review, a deficiency was discovered in the

, design of the exhaust fans for the diesel generator fuel oil tank

,

rooms. The diesel generator building'(DGB) tank room exhaust fan

'

motors are required to be class 1E and to be supplied from a class.1E-power source. Design considerations dictated that the motors be provided with a class IE power source to meet requirements of the STP Safety Evaluation Report, Supplement 1. STP design requires these j motors to be continuously energized on the class 1E power source which, in turn, requires qualified motors. Initial design, however,

'

had the motor power source classified as nonclass 1E. Consequently, the motors were purchased under nonsafety class specifications, rather than class 1E. The basis for this deficiency is these motors i were improperly procured as nonclass IE'for loading onto the class 1E power supplies. NRC subsequently agreed, in light of a revised i

ventilation and fire suppression design, that class IE fan motors

'

were not required. The fans previously purchased as nonsafety could

! be installed and receive their power from an ESF bus. The FSAR was

revised (Amendment 41) to reflect the design change. The NR : inspector reviewed the installation records which reflected the l installation of the three diesel generator fuel oil storage tank j exhaust fans. This item is considered close f Exit Interview  !
