2.1 Test Program Implementation Scope In the area of test program implementation, the inspector concen-trated efforts on the preparations being made for the. Engineered Safety Features (ESF) Integrated Test, the Hot Functional (HFT)

Integrated Test, the Turbine Building Hot Funtional Test (TB HFT)(see Section 4.0), and the Emergency Diesel Generator (EDG) problems.

2.2 Engineered Safety Features (ESF) Integrated Test The inspector held discussions with licensee representatives as to the status of the preparations being made for the ESF Integrated Test including procedures and prerequisites required to be completed in order to accomplish the test. The ESF test without loss of normal power will verify that engineered safeguard signals cause the appro-priate. safeguards components to actuate as well as overlap and oper-ation of reset and override functions. The ESF test with loss of normal power will demonstrate proper sequencing and operation of equipment under loss of normal power conditions, with and without safeguards actuation signals as well as verifying that separation

'

exists between emergency buses.

The inspector received draft copies of the ESF Integrated Test, for

. review and comment.

They are 3-INT-2003, "ESF Without Loss of Normal Power, and 3-INT-2004, ESF With loss of Normal Power." Many of the

-

prerequisites are not as yet completed to support the ! theduled for ESF testing.

The possible critical item.is the Emergency Diesel Generator (EDG) Sets.

The inspector expressed his concern for the resolution to the EDG problems and subsequent test of the EDG sets to support ESF testing.

The inspector will follow this item closely.

2.3 Emergency Diesel Generator Status The emergency diesel generator sets to date, are still in the test-ing stage of the preoperational test program with the EDG "A" set

,

mechanical and electrical load testing complete, and with the EDG "B" set with only mechanical testing complete. As documented in Inspec-tion Reports 50-423/85-10 and 50-423/85-14, the inspector pointed out the concern for the recurring problem of EDG fuel injection pumps seizing on both engines.

After the fuel injection pump problem is resolved on both engines, the electrical tests have to be completed for the "EDG" "B" set, and then both EDG sets have to successfully complete the 35 consecutive

'

starts on each EDG set in order to be qualified for use in the ESF Integrated Test. The inspector will follow this item closely.

2.4 Integrated Pre-Core Hot Functional Test (HFT)

'The inspector held discussions with licensee representatives as to the status of preparations being made for the Pre-Core Integrated Hot Functional Test. The inspector received a draft copy of the Integrated Hot Functional Test for review and comment, 3-INT-3000 Pre-Core Hot Functional Test, which is the controlling procedure for the entire integrated test.

.The integrated test performs the following objectives:

(1) To take the plant from a cold condition, through heatup, testing at 557 F, and then back to a cold condition.

(2) To verify freedom of movement during thermal expansion for major RCS components.

(3) To verify the capacity of the Chemical and Volume Control System (CVCS) to maintain RCS pressure during solid plant operations.

(4) To verify operation of the atmosphere steam dump valves and the steam dump / bypass valves during heatup and at normal temperature and pressure.

(5) To determine RCS heatup/cooldown rates for various plant conditions.

(6) To determine RCS heat loss at 557*F.

(7) To verify operability of the Plant Sampling Systems.

(8) To perform initial heatup of the secondary system and startup of the main feedwater pump turbine, the main generator and auxi-11ary feed water turbine.

(9) To determine RCS leakage rate.

(10) To perform initial boron and dilution of the RCS and the CVCS response to those tests.

(11) To perform initial vibration testing / monitoring on RCS Compo-nents.

(12) To functionally check the ability of the plant to be cooled down remotely.

(13) To provide a basic guideline for the sequence of performing l

various startup tests.

Along with meeting the above objectives, many other items are proven

and tested in the Integrated HFT. Supplementing the controlling pro -

cedure for the HFT are 33 appendices which range from individual tests to data gathering.

The inspector expressed concern that the 33 appendices are not avail-able as yet for review.

The licensee-stated that these procedures.

,

have been given priority and will be available for the NRC inspector to adequately review in a timely manner.

Discussion

'The witnessing of fuel receipt storage and inspection, was accomplished by the inspector during a three day period which included the arrival of the transportation truck, and unloading of the seven new fuel casks in the fuel building.

Documentation reviewed during this inspection included material transfer log; material accountability log; fuel receipt and inspection form; rod control cluster assembly receipt and inspection form; thimble plug receipt and inspection form; spent fuel pool map for fuel assembly location; visitor control access list area authorization; daily log of access and exposure _ control; radiation survey sheets; radia-tion permit; shipping container receipt and inspection sheet; transpor-tation truck bill of lading; and consignment of fuel from Westinghouse Electric Company to Northeast Utilities.

The inspector witnessed receipt, preparation, cleaning, inspection, and storage of six of fourteen fuel assemblies from arrival at the fuel build-ing truck bay to storage in the spent fuel pool. The activities included radiation surveys of the truck; outer metal casks; opening of the casks; the initial survey of the two fuel assemblies in each cask; the removal, cleaning and inspection of each fuel assembly one at a time; the final inspection and measurements at the new fuel-inspection station; and the final storage of each fuel assembly in the spent fuel pool.

Fuel assem-blies with rcJ control cluster assemblies were included in this shipment.

The inspecter also reviewed documentation and made observations, on a sampling basis, during this period, in the areas of administration, physi-cal security, health physics and radiation control, reactor engineering, quality assurance and quality control, and housekeeping and cleanliness.

QA and QC provided coverage for the entire fuel receipt evolution.

Findings The inspector verified by review of documentation, discussions with licensee's representatives and by observations and witnessing, that receipt, inspection, cleanliness, assembly and storage of new fuel assemblies, was accomplished in accordance with NRC license require-ments and licensee's approved procedures.

No items of noncompliance were identified and no discrepancies were noted during these inspections. The inspector will continue to observe and inspect this evolution of new fuel receipt, inspection and storage in subsequent inspections until all fuel is on site. The inspector had no further questions at this time.
