Exit Interview

The inspection

scope

and findings were

summarized

on April 3,

1987 with

those

persons

indicated in Paragraph

1 above.

The following issues

were

discussed

in detail:

(I) an apparent violation for failure to document

health

physics qualification trai ning (Paragraph

4)

and (2)

an apparent

violation for failure to perform adequate

start-up shield verification

radiation

surveys

(Paragraph

5).

Licensee

representatives

acknowledged

the

inspection

findings

and

stated

that

they

took exception

to both

apparent

violations.

In regard

to the first apparent violation, they

.

stated that training documentation

would have

been in place before any of

the contractor

employees

would have

been allowed to act independently

and

that they were not required 'to train contractor

personnel

or to document

training

programs.

In

regard

to

the

shield

surveys,

licensee

representatives

stated that the surveys

had

been adequately

performed

and

in accordance

with their procedures

and

FSAR commitments.

The licensee

did not identify as proprietary

any of the materials

provided to or

reviewed

by the inspector during this inspection.

In a telephone

conversation

on April 16,

1987,

between

the inspector

and

the

Environmental

and

Radiological

Control

Manager,

the

licensee

was

informed that

the

issue

concerning

undocumented

training

would

be

considered

an

Unresolved

Item~,

pending

subsequent

NRC review of the

timeliness

and adequacy of the licensee's

corrective actions.

3.

Licensee Action on Previous

Enforcement Matters

This subject

was not addressed

in the inspection.

Allegation

(RII-87-A-0024).

following concerns:

(2870024001)

On approximately

February

6,

1987,

the alleger

and

two

co-workers

were

working

on

the

236

Elevation of the Auxiliary,

Building when

an air monitor alarmed.

The alleger

and

one of the

co-workers left the

area,

but were

ordered

to return

by their

supervisor.

The monitor continued

to alarm during the entire time

that the alleger

remained in the area

(from 8:00-9:30 p. m.).

(2870024002)

The alleger

and

a co-worker notified the Health Physics

Field Office by telephone

between

8: 15-8:30 p.

m. of the* alarming air

monitor

on the

236

Elevation of the Auxiliary Building, yet they

never responded.

(2870024003)

The alleger

and co-workers

had received

Levels I and II

of General

Employer Training (GET).

They were told that they would

receive

specialized

training before

being

assigned

decontamination

work, which was never given.

Some of the other workers

had already

worked in contaminated

areas

in radwaste.

~

~

4.

Allegations Followup (99014).

a ~

This allegation

consisted

of the

Unreso

ve

stems

are

matters

about

which more

information is required

to

determine whether they are acceptable

or may involve violations or deviations.

(2870024004)

On February

13,

1987,

the alleger

and three

co-workers

were working on the

216 Elevation of the Auxiliary Building when an

air monitor alarmed.

The alleger's

supervisor

required

the workers

to remain in the

area

from 2:30-5:00

p.

m.

.

The air monitor was

alarming during the entire time.

(2870024005)

The alleger's

supervisor failed to notify health physics

on the alarming air monitors

on the

216

and

236 Elevation of the

Auxiliary Building.

(2870024006)

On February

19,

1987,

the alleger

was directed

by the

alleger's

supervisor

to enter

an

area

on the

216 Elevation of the

Auxiliary Building to

remove

contaminated

protective clothing, wipe

off pipes,

massolin

mop the floor, and clean

and dust.

The alleger

objected

to the assignment

because

the alleger

had not been trained

in decontamination.

The alleger

was then terminated for refusing the

assignment.

b.

Discussion

The inspector discussed

the substance

of the allegation with, licensee

representatives

and

interviewed licensee

employees

who may have .had

first hand

knowledge of the alleged

events.

The inspector

also

reviewed

licensee

records

and procedures

related to the allegation..

As a result of the review, the following was determined:

(1)

There

were

three

types

of monitors

(air radioactivity,

radiation,

and

process)

in the Auxiliary Building which gave

local audible

and visual

alarms.

The Particulate,

Iodine

and

Noble

Gas

(PING)

monitors

were

used

to

measure

airborne

radioactivity in work areas

and inside ventilation ducts.

The

- PING consoles

had only

a local alarm and strip chart recording

of the monitoring results.

The AMS-3 was

a work area airborne

radioactivity monitor which measured

only particulates

and gave

only local alarms.

The area radiation monitors

(ARMs) measured

general

area

radiation

levels

and

gave

audible

and visible

alarms locally at the console

and remotely to the control

room

and health

physics. field office.

The local

alarms

had to be

physically silenced

at

the

console (i.e.

they could not

be

silenced

from a remote location).

In many cases,

the area

being

monitored

was different from the location of the console, that

is the air sampler

or detector

would be, for example,.in

a

cubicle,

and

the console

would be outside

so that it would be

more readily accessible.

(2)

For several

days

around

the date of February 6,

1987,

process

radiation monitor REM-IMD-3530 on the 236 Elevation of the Waste

Processing

Building

had

been

periodically alarming

and

was

tagged

with

a deficiency

tag indicating that it was giving

spurious

alarms.

There

were

no records

of any other monitor

alarms during this time period in this location.

(3)

(9)

There

was

a record of a

PING alarm at 1300 hours0.015 days <br />0.361 hours <br />0.00215 weeks <br />4.9465e-4 months <br />

on February

13,

1987

on the

216 Elevation of the Auxiliary Building.

Licensee

health

physics

personnel

determined

that

the

alarm

had

been

caused

by

noble

gas

and

the

conditio'n

had

persisted

for

approximately

one

and

a half hours.

There were

no records of

any other alarms

on this date in this location.

The contractor personnel

had always signed into the work area

on

one of three radiation work permits

(RWPs),

as follows:

cm'he

alleger

had

made

175

RWP entries

during

the

period

November 10,

1986, to February

19,

1987.

The entries

in 1986

had

been

under

RWP 86-0110

and under

RWP H87-0012 in 1987.

The

alleger

had never worked under

RWP H87-0005, which was the only

one of the three

which involved work if> Lontaminated

areas

and

required that protective clothing be worn.

The alleger did not

make

any

RWP entries

on February 6,

1987,

but did make entries

on February 4,

1987 during the time period

that the monitor was allegedly alarming (i.e., 8-9:30 pm).

The

alleger's

next

RWP entries

were

on February 7,

1987,

but were

not made during the time period in question.,

The alleger

made three

RWP entries

on February

13, 1987, during

the period 4:26-10:44

pm.

The monitor was allegedly alarming

during the period 2:30-5:00

pm.

The alleger

was assigned

a total of 27 millirem for all of the

RWP entries

made in 1986

and

1987.

The alleger

had whole body

count measurements

performed

on November 7, 1986, January

13 and

February

19,

1987.

None of the counts

showed

any detectable

radioactivity, except for naturally occurring potassium-40.

The alleger

had successfully

completed

General

Employee Training

(GET)

Levels

I

and II.

GET Level I training

was

general

familiarization training

which

enabled

a

person

to receive

dosimetry

and enter

the plant protected

area.

GET Level II

covered

use of protective clothing,

RWP procedures

and response

to warning devices.

GET Level II training qualified the person

to work under

a

RWP, including work in a contaminated

area.

(10) The contractor

employees

had worked inside the plant controlled

area

performing general

housekeeping

duties

such

as mopping

and

emptying trash

cans.

The licensee

had

determined

that they

wanted the'ontractors

to begin

working

as

decontamination

personnel

("deconners")

cleaning

up

areas

as

they

became

contaminated.

The contractors

were also to be used to "frisk

trash," that is to perform surveys of materials

from the plant

controlled

area

so that it could

be released

for unrestricted

use.

A health physics technician

was assigned

to each shift and

was

required

to

provide

continuous

coverage

while

the

contractors

were

performing decontamination

or were frisking

trash.

Contractor

personnel

were

being

rotated

into the

contaminated

area

duties.

This work under the supervision of a

health

physics

technician

had

been

described

to the contractor

management

and

employees

as

on the job training

by licensee

representatives.

There

was

no

formal training

program or

documentation for this qualification training.

The licensee

had

prepared

a three

hour class

on decontamination

techniques

and

had

scheduled it to be presented

in mid February

1987, but it

was

reportedly

cancelled

because

of

a

snow storm.

Licensee

representatives

stated

that

they

intended

to

provide

qualification cards for the contractors

in the future.

Technical Specification 6.4. 1 requires

that

a retraining

and

replacement

training

program for the unit staff shhll

be

maintained.

Carolina

Power

and

Light Nuclear Training Section

Training

Manual, July 16,

1986,

which specified

the licensee's

training

policy,

required

that

training

programs

be

conducted

in

accordance

with written

procedures,

that

there

be

course

outlines, job task analyses

and examinations.

c.

Findings

(Concern

2870024001)

This concern

was substantiated.

There

was

an alarm

on the

date

and time and in the

area

alleged.

The

supervisor

did tell the workers to return to the area

based

on

information

he

had

received

from the assigned

health

physics

technician

regarding

the deficiency tag that was

on the monitor.

It could not

be

independently

established if the supervisor

explained to the workers the reason that they could go back to

the

work area.

The

coworkers

in the area

were told of the

deficiency tag

on the monitor when health

physics

was called.

The alleger

was

reportedly

shown

the deficiency

tag

by

a

coworker.

The inspector

determined

therefore that the alleger

had sufficient information provided to understand

there

was

no

radiological

hazard

in the area.

No violations or deviations

were identified.

(2)

(3)

(4)

(Concern

2870024002)

This concern

was not substantiated.

The

licensee

did not maintain

any documentation

of when personnel

responded

to

and

silenced

alarms.

The status

of

ARMs was

monitored

by

a health

physics technician in their field office..

In

many

cases,

the

technician

could

determine

from the

computerized

monitoring terminal if the

alarm

was

due to

a

malfunction.

The

known spurious

alarm was not given

as

high a

priority to sending

a health physics technician to investigate

and silence.

However, it could not be established

when, or if,

the alarm was investigated

by health physics or for how long the

alarm

continued.

The

inspector

discussed

with licensee

representatives

the importance of promptly responding

to alarms,

even if they

are

thought

to

be

spurious.

Licensee

representatives

stated that their health physics

personnel

would

be

so instructed.

No violations or deviations

were identified.

(Concern

2870024003)

This concern

was partially substantiated.

The contractors

had

received

GET Levels

I and II training and

there

was

an

intention that

they

would receive

additional

training specific to decontamination.

However, it could not be

e-tablished if they were told they would receive this training

prior to being

assigned

decontamination

work,

The inspector

determined

that the informal

on the job training that was given

was apparently

not consistent with Technical Specification 6.4. 1

and the licensee's

policy as stated

in their corporate training

procedure.

Performance

of free release

surveys

was normally

a

task

required

to

be performed

by

a health

physics

technician

acting

in

a responsible

position.

However,

the licensee

was

committed

to

the

1979 draft of

ANSI 3.1,

which permitted

individuals,

not fully qualified, to perform, specific tasks if

they

had

been

trained

and qualified

on those specific tasks.

The

licensee

was

in

the

process

of

conducting

limited

qualification training, yet

had

no procedure,

lesson

plans,

qualification cards,

or other documentation

or specification for

this training.

Failure to adequately

conduct health

physics

qualification training

program

was identified

as

an apparent

violation of Technical Specification 6.4.1.

However, consistent

with

the

Commission

Policy

Statement

on

Training

and

Qualification

and

the

memorandum

of understanding

with INPO,

this matter will be

designated

an

unresolved

item pending

subsequent

NRC review of the acceptability of the licensee's

corrective actions for this matter (50-400/87-14-01).

(Concern

2870024004)

This concern

was partially substantiated.

There

was

a

PING alarm,

but there were discrepancies

that could-

not

be

resolved

regarding

the

time of the

alarm

and

the

'orresponding

times that the alleger

had

been

present

in the

area

as evidenced

by the

RWP time sheets.

As with the previous

concern,

the

time the, alarm

was

silenced

could

not

be

established.

No violations or deviations

were identified.

O

(5)

(Concern

2870024005)

This concern

was not substantiated.

It

was

independently

confirmed that the supervisor

had discussed

the alarm

on the

236 Elevation with health

physics

and

had not

been

present

when the alarm occurred

on the

216 Elevation.

No

violations or deviations

were identified.

(6)

(Concern

2870024006)

This concern

was partially substantiated.

The alleger

was given

an assignment

to work in a contaminated

area,

which was refused.

It could not be confirmed that lack of

training

had

been

raised

as

an issue

by the alleger.

Persons

who

observed

portions

of the

events

of February

19,

1987,

recalled

the alleger

complaining that the protective clothing

was not the proper size

and that the alleger

preferred to have

a

job outside

a

contaminated

area.

By all

accounts

by the

alleger's 'coworkers,

no request for additional

information or

instruction in health physics matters

had ever

been

refused

by

contractor or licensee

management.

No violations or deviations

were identified.

d.

Conclusions

10 CFR 19. 12 require's that individuals working in or frequenting

any

portion of a restricted

area

shall

be instn.'cted

in certain topics,

which include precautions

or procedures

to minimize exposure,

the

purposes

and

functions

of protective

devices

employed

and

the

appropriate

respon

'e to warnings

made in the event of any unusual

occurrence

or malfunction that

may involve exposure

to radiation or

radioactive material.

The inspector

determined that the alleger

had been adequately

trained

pursuant

to

10 CFR 19. 12 by virtue of having successfully

completed

GET Levels

I and II.

The decontamination qualification training did

not meet the Technical

Specification

requirements

for such training,

however, participation in the training would not have compromised

the

immediate

safety of the workers involved since

continuous

coverage

was always provided by health physics

personnel.

with

licensee

representatives.

Licensee

representatives

stated

that

ANSI/ANS-6.3. 1-190,

Program for Testing Radiation Shields

in Light Water

Reactors

(LWR), was utilized as

guidance for preparation

of the shield

survey

procedure.

In contrast

to

ANSI/ANS 6.3. 1, Sections

5.4.3. 1

and

5.4.4.2,

respectively,

the licensee

procedure

did not require

surveys of

auxiliary shielding required during power operations

nor extrapolation of

survey results

to rated full power.

The inspector

informed licensee

representatives

that

FSAR

Section 12.3.2

details

auxiliary shielding

design criteria

and also describes

the radiation

access

zones

based

on

maximum

dose

rate

levels.

Licensee

representatives

stated

that

the

original

procedure

required

extrapolation

of the shield survey, results

conducted at

50% power to rated full power,

however,

the requirement

was

deleted

during subsequent

procedure

review.

The failure to extrapolate

exposure

rates at

50% power to rated full power and the failure to conduct

shield surveys of auxiliary shielding associated

with sources

external

to

containment

was identified as

an apparent

violation of 10 CFR 20.201(b)

(50-400/87-14-02).

Techniques

utilized in performing the shield

survey were discussed

with

selected

personnel

who had conducted

the

50% power plateau shield survey.

6.6 and 6.11 of SUM-1-9103-33 require that during shield surveys

the radiation

survey

instrument

is held

about

1 meter

from the wall

Radiation

Base Points

(RBP) and that the radiation levels are continuously

monitored

while proceeding

from one

RBP location to the next.

From

independent

discussion

with selected

individuals the inspector determined

that contrary to the

approved

procedure,

several

technicians

conducted

10

contact

radiation

survey

measurements

and

also failed to continuously

monitor radiation

exposure

rates

between

RBPs.

The failure to follow

approved

procedures

was identified as

an additional

example of failure to

adequatl ey

perform

surveys

as

required

by

10 CFR 20.201(b)

(50-400/87-14-02).

FSAR Section

12.3.2.2 details

the radiation

access

zones

based

on the

maximum zone

dose rate levels.

At 50% power approximately

12

RBP survey

locations at inside containment,

mainly on the

286

elevation,

exceeded

the

100K

power

zone

access

limits identified in

FSAR Figure 12.3.2-3.

Licensee

and

vendor evaluation

determined

that calculated

exposure

rates

for this

FSAR Figure failed to include the neutron

dose rate contribution.

Licensee

representatives

stated that the radiation

zone areas

described

in

the

FSAR would be modified accordingly.

During the inspection

independent

verification of

gamma

and

and neutron

shield

survey

exposure

measurements

were

conducted.

Measurements

were

made

on selected

plant elevations

at the outside

containment wall

RBPs

and

penetration

areas

and at auxiliary shielding associated

with radiation

sources

outside of containment.

All survey results

were within

FSAR

limits.

IE Inspection

Report

No. 50-400/86-43

identified potential

personnel

radiation

exposure

hazards

associated

with movement

and storage

of the

incore detectors

in the seal

table

room.

Details regarding

the expected

exposure

rates

and associated

shielding

requirements

were reviewed during

the

inspection

(Letter

from A.

C.

Anderson,

Project

Manager,

EBASO

Services,

to L. I. Loflin, Manager,

Engineering

SHNPP, dated

September

4,

1986).

Dose rates

at the door to the seal

table

room from an activated

detector

and cable

was estimated

to be approximately 2.4 R/hr.

A survey

conducted

February 3,

1987, with the reactor at

30K power

and

3 incore

detectors

located

above

the five pathway

mechanism

indicated

exposure

rates

of 250 mR/hr at

the

entrance

to the

seal

table

room.

Vendor

recommendations

for minimizing radiation

exposure

included administrative

controls and/or the addition of a shield door or concrete wall.

Presently

the matter is addressed

by procedural

controls

and

no shield modifications

are

planned

in the

near

future.

Procedure

OP-106,

Incore

Movable

Detectors,

dated

August 13,

1986,

requires

that the Radiation

Controls

Foreman or his designee

must verify that all personnel

are outside of the

secondary

shield wall

and other

areas

designated

by the

RC technician

prior to movement of incore detectors.

Licensee

representatives

stated

that utilization of administrative

controls

and the potential

need for

additional

shielding

associated

with the

seal

table

room to prevent

potential

exposure

problems

was being evaluated.

The inspector

informed

licensee

representatives

that review of radiation controls associated

with

the

seal

table

room would

be

considered

an

inspector

followup item

(50-400/87-14-03).
