conducted on February 6 and March 10, 1987.

2. Licensee Action on Previous Inspection Findings

(Closed) Open Item 498;499/8704-01 Access Control System

This open item concerned the inordinate number of people on the fuel

handling building (FHB) access list just prior to receiving the first

shipment of new fuel. The licensee agreed that the number of people on

the access far exceeded the number of people that had routine jobs to

-.

. .

4-

perform in the FHB. The licensee revised the access system to allow for

authorization for a limited amount of time to those people that.had a

short term assignment in the FHB. The unescorted regular access list was

reduced to a minimum number of people which primarily included operations .

crews, security, some maintenance staff and management. -The NRC inspector

reviewed the new access control procedures and the list of those on the

regular access list and found it to be acceptable for the_ receipt of new

fuel.

(Closed) Open Item 498;499/8704-03 Comunication

This open item concerns the ability to communicate by radio.between the

various security patrols, FHB access control points and main security

office. The licensee was experiencing dead zones in this communication

network. The problems were resolved and the NRC inspector witnessed a

test of all the radio comunications to, from and within the FHB. This

test included a response by the shift security coordinator to the FHB

cccess control point. During this inspection, it was noted by the NRC

inspector that shift relief took place on station and that all the radio

battery chargers were located in the main security office (away from the

FHB). This could_ lead to loss of field radio communication due to dead

batteries. This item was discussed with the licensee and one battery

charger (for eight batteries) and spare batteries were relocated to the

FHB main access control point; ,The above activities were witnessed by the

NRC inspector and are satisfactory for the receipt of new fuel.

(Closed) Open Item 498;499/8633-02 Hot Functional Preoperational Test

This open item concerns the incorporat! ion or resolution of NRC review

coments to Preoperational: Test 1-RC-P-02, hot' functional test (HFT). The

licensee has revised and reissued the HFT test with the resolution of all.

NRC provided comments.

'

(Closed) Deviation 498/8633-01- Preoperatio'nal Test Procedure - HFT

This deviation concerned the timely availability of'preoperational test

procedures to the NRC for review as required-by Section 14.2.11.5 of the ;

'

Final Safety Analysis Report (FSAR). The comitment was "approximately

60 days." The HFT preoperational test (1-RC-P-02) was available 56 days 1

before the test which is within "approximately." However, the HFT l

procedure was primarily a parent document that leads the licensee through

22 other subordinate tests. Within two weeks of starting the HFT, five of

these 22 subordinate tests had not been issued. Additionally, the HFT

makes use of 86 modified plant operating procedures which were not

available in this_ modified form. The NRC inspector considered this a

deviation from their FSAR comitment.

The licensee responded by expediting the generation of the required tests

and procedures in time to allow the NRC inspectors time to complete this

review. This was_ accomplished by reviewing the tests and procedures in

i

-

n .

. .

'

'

the order identified in the HFT. The NRC' inspectors did complete their

reviews and the licensee has a clear understanding of the commitment under

Section 14.2.11.5 of the FSAR. This deviation is considered closed.

3.- New Fuel Receipt

The first shipment of new fuel ' arrived at the STP at 2:00 a.m (CST)

January 28,1987. There were four containers, two assemblies per

container for a total of eight assemblies. Health ~ Physics (HP) and

security. preparation and inspections were meticulous. The truck was

secured in the FHB by 5:00 a.m. on January 28, 1987. The_NRC inspectors

' observed the fuel receipt activities . including a review of the material

license and shipping and inspection' records. The assemblies were removed

from the canisters and placed in the new fuel storage racks. The NRC

inspector observed various portions of this activity including HP controls

and activities, security access control and use of procedures during this

evolution. The NRC inspector performed an independent radiation survey

l and container integrity examination. The results of these examinations

l were negative.

Fuel receipt continued during this inspection period at the rate of one -

shipment per week _for the first two weeks and two shipments per week

thereafter. The NRC inspectors have witnessed selected activities of most

fuel receipts (fuel receipt being from the time arrived on site until

placement in storage racks). ,

On February 18, 1987, the NRC inspector witnessed the inspection of two

fuel assemblies as performed by Nuclear Plant Operations Department -(NP0D)

personnel and Operations Quality Control (QC) inspectors. The two fuel

assemblies inspected were:

Container Assembly ANSI No.

l

004 C50 LM0K4L

004 C38 LM0K4X

Prior to i;he inspection, the NRC inspector reviewed PGP OPGP03-ZL-0002,

Revision 4, "New Fuel Receipt, Inspection and Storage," which defines

requirements and inspection attributes for the receipt, inspection and

storage of fuel containers and assemblies; The procedure also defines the

responsibilities of the Technical Support Division, Health and Safety

Services Division', Reactor Operations-Division, and Maintenance Division

personnel during fuel' shipment inspections.

,

During the fuel -inspection, the NRC inspector noted that the latest

revision of the approved inspection procedure was in use by inspection

personnel. Radiation Work Permit 87-1-0036-A, which defines the type of

radiation work, was also in use as required by procedures. Observations

I and conversations with the inspection personnel-indicated that they were

l familiar with the procedure and its requirements.

i The NRC inspector noted discrepanciesLin documentation during review of .

fuel assembly data. sheets. For each.of the two: fuel assemblies inspected,. >

there was a discrepancy in the. recording of contamination survey results.--

' Step 8.4 of the inspection procedure requires;that a contamination survey .

. of.each fuel assembly be perfonned. If,the removable alpha contamination-

exceeds 20 dpm, the fuel assembly must be isolated.and precautionary

measures taken. , Review of data sheets ' indicated recordings'of less than'

4

50 dpm, which could exceed the limit of 20 dpm, yet no precautionary;

measures were taken as required by procedure. Conversations with licensee

i .

personnel revealed that the alpha contamination results were inaccurately

1 recorded. The contamination results were less than-20 dpm but recorded as

less than 50 dpm which exceeds.the procedural limit. (Review of the 32 '

-

previous fuel assembly data sheets revealed that one other contamination.

j survey result was inaccurately recorded.

j ' Further review by the-NRC inspector indicated inconsistencies-in recording

. of the drag-load forces for particular fuel assembly inserts. Some_ data' - >-

.:

sheet recordings consisted of the insert weight plus. the' drag-force of the !~

insert, while other consisted of the drag-force only. ;This inconsistency,

along with inaccurate contamination recordings. indicates that personnel

~

F

i may not have been completely familiar with procedural-requirements.

c -

-

,

_

1- The above inaccurate alpha contamination recordings are a. result of

3

failing to properly follow procedures-in the recording of the correct '

i alpha contamination and constitutes an apparent violation of the

requirements of 10 CFR 50, Appendix B Criterion V which requires '

j adherence to procedures. (Violation 498/8703-01)

indicates that-the licensee has provided a means for unimpeded access ~ '

4 through security controlled doors during emergencies.

The Physical Security Plan provides for the suspension of safeguards-

measures in an emergency in accordance witn p6ragraphs 50.54(x) and (y)'of

i 10 CFR Part 50. This provision will accommodate the potential _need for- u

l

rapid response to emergency conditions. Emergency Plan Implementing l

The NRC inspector has reviewed both the STP-PSP and referenced procedure

and has determined the licensee's actions acceptable.

(Closed) IEC 77-13

" Reactor Safety Signals Negated During Testing." This circular pertains

to a potential industry problem with a lack of management control of ~

equipment status and improper attention of plant personnel to plant

procedures. The concerns of this circular are adequately addressed in

licensee approved procedures. The following procedures were revi,ewed by

the NRC inspector for closure of the circular:

. STPEGS Plant Procedure OPGP03-ZA-0010, Revision 2, " Plant Procedures

Compliance, Implementation, and Review," requires that plant

procedures be strictly adhered to when performing plant activities.

. STPEGS Plant Procedure OPGP03-Z0-0001, Revision 2, " Equipment

Clearance," requires unit / shift supervisor approval of equipment

clearances for safety-related equipment.

. STPEGS Plant Procedure OPGP03-ZE-0004, Revision 2, " Plant

Surveillance Program," requires shift supervisor permission prior to

commencement of safety-related component or system surveillance

tests.

(Closed) IEB 74-07

" Personnel Overexposure - Irradiation Facility." This bulletin described

an event at an irradiation facility in which an experienced operator

received an overexposure from entering an area with a source in the

unshielded position. Action one required by the bulletin is not

applicable to STP. In lieu of control devices and interlocking alarms,

the licensee utilizes the barricades method, permissible by

10 CFR 20.203(c)5. Action two required by this bulletin is

administratively controlled. PGP OPGP03-ZR-001 through -009 constitutes

that control and complies with 10 CFR 20. Special training required by

action three has been verified complete. The licensee's actions

adequately address the bulletin's concerns.

(Closed) IEB 78-07

" Protection Afforded by Air-Line Respirators and Supplied-Air Hoods."

This bulletin recommends that licensees address listed items with respect

to their respiratory protection programs. The licensee has adequately

addressed the bulletin in its FSAR, Section 12.5.3.5.

operators. The-flash tanks were not available and blowdown was

going to.be directed to Condenser 13. The inspector observed

. Condenser 11 vacuum pressure gage was r.ot operational.

Additionally, operators explained to the inspector that the

-

analog _ readouts were _in absolute pressure in lieu of gage

pressure and are not designated as either. Both the inspector

and several operators interviewed found the situation confusing-

primarily because it is inconsistent with the rest of the

control room pressure instrumentation.

. Several problems were identified with the reactor coolant

pumps (RCPs)' during HFT. These problems are being tracked by

the licensee under the 10 CFR 50.55(e) or incident review

committee (IRC) program and will'be closed out via the normal.

NRC closure. On January 20,1987,, RCP 1C experienced a breaker -

failure caused by improper racking in-of an intermediate pump

breaker. On January 21, 1987, RGP IC experienced a seal

leak-off problem. On January 25, 1987, Cold Leg RTD, TE-461,

Was identified as having a leak around the seal weld between the

pipe boss and the RTD thennowell. This incident required

stopping the HFT, depressurizing and draining the RCS. Fifteen

other- RTDs were checked and causes of the leaks were identified

as improper installation of "6" rings in the pipe bosses and

faulty. seal welds. Repairs whm ' satisfactorily completed. On

February 6,1987, RCP ID experienced a ground due to loose wire

at the pump terminal. On February 14, 1987, RCP 1C experienced

a low seal flow problem.

The preceding problems were addressed by the licensee in a

timely-and appropriate manner with a minimum of test

interruption. They will be reviewed by the NRC when the

appropriate closure documentation is completed by the licensee.

b. Other Preoperation Test Witnessing

(1) During this inspection period portions of other test witnessed

by the NRC inspectors include:

. 1-AF-P-01, Auxiliary Feedwater System - Motor Driven

. 1-DG-P-01, Diesel Generator No.11

. 1-DG-P-02, Diesel Generator No. 12

. 1-HF-P-01, FHB HVAC System

. 1-RS-P-01, Rod Control System

. 1-CC-P-04, Component Cooling Water System Balance

. 1-CS-P-03, Containment Spray, Train C

(2) Test Observations

Several problems were encountered during the. diesel generator

testing. These problems are being tracked by the licensee under

the IRC programs for 10 CFR 50.55(e) reports and will be closed

out via the normal NRC closure. On January 14, 1987, 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br />

into the 24-hour run on Diesel Generator No.12, No. 3 right-

push rod became stuck. It was determined to be a failed roller

lifter. The No. 3 right head assembly was replaced, engine

repaired and returned to~ testing. On January 24, 1987, Diesel

Engine No.12 failed to start on attempt No. 9, series of 23.

The starting air filter on both starting air lines vibrated

loose and blew off. . Repair and temporary modification was

completed and the 23 start sequence was restarted. On February 25,

1987, the 24-hour run on Diesel Engine No. 11 was stopped.due to

high lube oil sump level. This was caused by a cracked injector

which allowed approximately 50 gallons of fuel oil to leak into

the lube oil sump. Testing was stopped, lube oil sumps, pumped

down, injector replaced,- engine checked, and testing resumed.

On March 2, 1987, the 24-hour run on Diesel. Engine No. 11 was

stopped due to high pressure fuel line leakage (spray at ferrule

points) between the fuel inspection pump and the injectors.

Repair was completed and testing restarted.

All of the above diesel problems were discussed with the vendor,

Cooper Energy System by the licensee and with.the NRC vendor

group by the NRC resident inspectors. Closure of these

occurrences will be by the normal closure process.

No violations or deviation were identified.

7. Training Review - GET

The NRC in'spector attended GET II, which provides radiological training

for the employees and made the foll_owing observations. The course
