(2)
The inspector witnessed the licensee test performance in the areas of boration and deboration and the validati of operating procedures and calculational techniques.
The following concerns were identified and require licensee action for resolution:
Revision of OP 2103-1.2 to include revised Baron Addition Pump Stroke vs Concentration Curves to reflect (a)
test data.
Modification to the agitator on Boric Acid mixing tank (b)
to aid in proper mixing.

(5) TP 204/3 Reactor Buildina Soray Pumos The inspector witnessed the licensee's demonstration of the BS-P-1B spray pump in the area of head curves.
Three points were demonstrated and fell within the acceptance criteria. The maximum flow attained in the surveillance made of operation of recirculation was 1080 gpm.
Discussion with vendor field engineer indicated that the original icw flow problem was due to interposing the curves for BS-PIB with BS-PlA.
The BS-P-1B pump test curves did demonstrate that pump capability was in excess of 1500 gpm.
The results of testing of BS-PlA will be reviewed at a subsequent inspection.
c.
Parameters Observed The inspector observed the following parameters for each test witnessed:
Procedure Availability
--
The inspector verified that the official copy of the approved procedure, TP 600/28, was available in the control room and used by test personnel.
The inspector verified that official approved copies of the test procedures were in use for all tests witnessed.
Crew Mannina
--
The licensee established a shift test engineer to coordinate testing. Additionally a test engineer was assigned to cover each test procedure in progress.
The normal operations crew manned the control room and consisted of a Shift Foreman plus
-
several control and equipment operators.
Prerecuisites and Initial Condition
--
Extensive prerequisites and initial system conditions were contained in each test procedure (TP).
The inspector verified that prerequisites and initial conditions had been signed off or properly resolved by test exceptions or Test Change Notices.
The inspector verified by independent effort that selected prerequisites in the HFT program had been accomplished.
These prerequisites included system valve lineups, water chemistry specifications, and system operability.

Soecial Test Ecuioment
--
The inspector verified the special test equipment required by the TP's was in use and th?t current calibration stickers were affixed to the equipment.
--
Test Performance The inspector verified, through observations of testing and a sampling review of TP's, that the testing was performed as required by the procedures.
The TP's were found to be properly documented to indicate changes, identify problems encountered an show adherence to procedural steps.
Crew Performance
--
The inspector observed that test personnel engaged in the test program were briefed at each shift change and prior to the performance of testing.
Test personnel actions under planned and unplanned conditions, which were observed by the inspector, appeared to be ccrfucted in an orderly manner.
Communications were maintained between test and operations personnel during the conduct of the testing.
Data Collection
--
The inspector verified for those tests witnessed, that all data required by procedure was recorded on the appropriate data sheets and was completed to the intent allowable, based on the test completion status.
--
Test Results
,
The formal results of the testing had not been reviewed and
-
approved by the licensee at the conclusion of this inspection.
These results will be reviewed during a subsequent inspection of the licensee's preoperational test program.
The inspector had no further questions on the tests witnessed except as noted in the above paragraphs.

Reactor Coolant Pumos During the HFT program the RCPs exhibited leakage between the inner and outer flexitallic gasket joints at the pump machined lands to the reactor coolant loop volute. The resolution of this item will be reviewed during a subsequent inspection.

Carbon Steel in Boric Acid Containinc Svstems During a tour of the facility the inspector noted what appeared to. be carbon steel nuts and studs installed in stainless steel systems that contain boric acid. The specifications for the Architect-Engineer and NSSS were reviewed in this area.
It was noted the A-E's specifi-cation required the use of stainless steel nuts and studs in stainless steel systems. The NSSS specification allowed the use of steinless or carbon steel. The inspector indicated that this area would This item receive further review during a subsequent inspection.

Findings The inspector identified one area of concern in his review of TP 260/3 Condenser Air Extraction Functional Test. The licensee has failed to demonstrate the ability of the standby air extraction pump to start at an increase in pressure of 5" Hg absolute. The calibration records and procedure content fail to support the requirements of system as (

The licensee stated that the pressure switches activating standby pump will be recalibrated and tested. This item is unresolved (320/77-40-04) pending ccmpletion of recalibration.
No other items of concern were identified.

evaluation.
Findings The test Working Groco at meeting #80, September 29, 1977, reviewed and approved TP 330/2 Control Red Drive Control System Operational Test. The inspector reviewed twenty-five test exceptions including eleven test deficiencies. A sampling of the data of the test results identified no inspector concerns.
The QA inspection involve-ment in initial testing identified no concerns. The inspector has no further questions concerning the licensee's evaluation of test results.
8.
Outstanding Items Review A review of Region I open items and the licensee's construction completion was conducted to attempt to ascertain the status of the facility for the issuance of an operating license.
This review was performed by the Operations and Construction Project Inspectors in The results of conjunction with the Licensing Project Manager.
