DETAILS 1.

Persons Contacted Principal Licensee Employees

  • J. Evans, Station Superintendent

.

  • L.

Stalter, Technical Engineer

  • J. Ligenfelter, Nuclear and Performance Engineer
  • W. Green, Assistant to Station Superintendent
  • J. Buck, Operations Quality Assurance Manager R. Zemenski, Operations Engineer
  • S.

Batch, Tech Staff

  • E. Michaud, Test Program Manager (B&W)

The inspector also talked with and interviewed other licensee employees, including members of the technical and engineering staff, reactor shif t crews, training department members and startup test

,

leaders.

.

  • denotes those attending exit interview.

2.

Deferred Preoperational Tests g j The inspector reviewed the following deferred * preoperational tests to determine the status of outstanding deficiencies.

T.P. 256.02 - Station and Instrument Air Acceptance Test.

Testing was completed.

,

T.P. 271.09 - Main Steam Isolation valve Test.

Operation of the main steam steam isolation valves was verified dur-ing mode 4 operations.

Final close out of deficiencies and additional retesting is scheduled during mode 3.

T.P. 600.4 - Make up and Purification System Test.

The two outstanding deficiencies were corrected and retested. Check out of the redesignated letdown orifice will continue through mode 3 to full system pressure and temperature.

  • completion of certain portions of these tests had been deferred l

uniti af ter fuel loading when conditions would permit retest.

3.

Status of Preoperational Testing to be Completed Prior-to Mode 2 The current status of deferred preoperational testing to be completed prior to mode 2 (initial criticality) was reviewed.

Within this review a representative of tne licensee stated that all testing is

,

presently scheduled to be completed except in two areas.

These areas are:

.

T.P. 100.01 - Communication System All part of the testing will be completed except for final signoff on the turbine <11 ding. The licensee proposed to postpone the final acceptance of the turbine building area until after the tur-bine is in operations (Mode 1)

T.P. 230.1 - Clean Liquid Waste System The backup clean waste booster pump is not scheduled for delivery

,

until mid August. The system has been tested, but this deficiency would remain open until the repaired pump is installed and run.

-

4.

Plant' Tour

'"N, The inspector walked through various areas of the plant to observe

)

operations and activities in progress, to inspect the general

' - '

state of cleanliness, housekeeping and construction activities.

Repair work on the makeup pump and leaking packing on the contain-ment spray pump was discussed with representatives of the licensee.

No items of noncompliance or deviations were identified.

5.

Review of Nonroutine Events Reported by the Licensee The inspector reviewed licensee actions with respect to the follow-ing listed nonroutina events reports to verify that the events were: reviewed and evaluated by the licensee as required by Techni-cal Specifications, that corrective action was taken by the licensee, and that safety limits, limiting safety system settings, and limit-ing conditions for operation were not exceeded. The inspector examined selected Station Review Board minutes, licensee investi-

.

gation reports, logs, and records, and inspected equipment and

interviewed selected personnel.

Loss of Decay Heat Flow in mode 5 Due to Accidental Shorting (NP-32-77-02).

Loss of Decay Heat Flow in mode 5 Due to Closure of DH-ll (NP-32-77-03).

Loss of Both Source Range Nuclear Instrumentation Channels while Performing Preoperational Test.

(NP-33-77-1)

Channel Checks required by Table 4.3-2 of Technical Specifications were not being checked.

(NP-33-77-S)

No items of noncompliance or deviations were identified., The inspector noted that the licensee had identified and corrected three infractions with Technical Specifications related to these events.

6.

Response Time Testing The inspection reviewed the response time testing performed for measuring the sensor portion of the reactor coolant pumps loss to the "High Flux / Number of Reactor Coolant Pumps On" of the Reactor Protection System (Table 3.3-2(8) of the Technical Specification).

It was noted that the results were apparently conservative because the pump breakers were included in the time.

The current trans-formers on one phase of the 13.8 Kv leads has a calculated response

.

time of less than 1 millisecond. The breaker time is considerable longer therefore the conservatism.

The inspector has no further questions on this subject at this time.

7.

Organization Changes g

j s/

s The licensee announced that they were creating the position of Assistant Station Superintendent.

The current Operations Engineer had been designated to fill the position.

Mr. R. Zemenski had been designated to fill the positions of Operations Engineer.

The inspector reviewed the qualifications of both Messers.

T. Murray and R. Zemenski against ANSI N18.1.

The inspector has no further questions at this time pending FSAR and Technical Specification changes to describe the new position of Ascistant Station Superintendent.

8.

Exit Interview The inspector met with licensee representatives (denoted in Para-graph 1) at the conclusion of the inspection on July 7,1977.

The inspector summarized the scope and findings of the inspection.-

The licensee representative made the following remarks:

Acknowledged the statements by the inspector with respect to non-routine event reports and the noncompliance reported and corrected by the licensee.

(Paragraph 5)

(h

Stated that based upon the current schedule the plant.should be in mode 3 by July 11, 1977, (Paragraph 2) and that deferred pre-operational test prequisites of mode 2 should be complete by July 20, 1977, (Paragraph 3).

The inspector stated that he would review the exceptions on TP 100.01 and TP 230.01 (Paragraph 3)

and would inform the licensee at a later date.

The licensee requested the status of the review on TP 71'0.01, Zero Power Physics Test (Inspection Report No. 50-346/77-16).

The inspector stated that the test procedure was still under review and that he would inform the licensee as soon as the review was completed.

The licensee stated that they would be submitting a FSAR and Technical Specifications change to cover the proposed plant organ-izational change (Paragraph 7).

The licensee requested that the inspector designate which power

,

ascension tests that he wanted to be kept informed as to the date they would be performed. The inspector stated that he wanted to

.

be kept informed on the date of initial criticality. As to which other power ascension tests, the inspector would notify the licensee later.

(O After the inspection and exit interview, on July 11, 1977, the

\\._-

inspector called the licensee and informed him that based upon

.

the NRC review, the stuck rod - shut down measurements of TP -

710.01 (ZPPT) must be performed within the constraints of the accident analysis in the FSAR for the ejected rod accident or an new accident analysis must be submitted to NRR for review.

As presently written the proposed test measurement involves operation with control rod configurations.that allows the potential worth of an ejected rod to be greater than analyzed in the FSAR and could result in an unanalyzed accident.
