This

unannounced

inspection

of radiation

protection activities

included

a

review of the licensee's

organization

and

management

controls, training

and

qualifications,

external

and internal

exposure

controls,

as

low as

reasonably

achievable

(ALARA) program,

surveys

and control of radioactive material,

and

follow-up of previously identified items.

Results:

Two violations were identified.

One violation was identified for failure to

have

adequate

written procedures

for controlling access

and activities in high

radiation

areas.

Another violation was identified for failure to maintain

positive

access

control

to. a high radiation area.

Overall, the licensee's

radiation protection

program

appears

to

be generally effective in protecting

the health

and safety

of the workers.

Licensee

policy,and

procedures

for

qualifying vendor

HP personnel

was

a program strength.

The licensee

exposure

goals were agressive.

Organization

and Management

Controls

The inspectors

reviewed the licensee's

organization, staffing levels,

and

lines of authority

as

they related to radiation protection

program,

and

verified that the licensee

had

necessary

staffing levels to monitor and

control outage

work activities in radiological

areas.

The inspectors

discussed

with the Radiation

Protection

Supervisor

the

type,

methods,

and

degrees

of interaction with other plant work groups

during the Unit

1 refueling outage.

The inspectors

determined that the

licensee's

radiation protection organization

was adequately

structured

to

support the refueling work.

The inspectors

reviewed

the licensee's

program for self-identification

of weaknesses

related

to

the

radiation

protection

program

and

the

appropriateness

of corrective action taken.

In a previous inspection,

the

inspectors

determined

that the licensee

was not identifying radiological

protection

program problems or deficiencies

in a corrective action program

to determine

root causes

and corrective actions.

However,

no violations

of

NRC

requirements

were identified

and

a

continued

review of the

licensee's

practices

for initiating

and

documenting

radiological

protection

program

discrepancies

will be

reviewed

during

subsequent

inspections.

The licensee's

procedure

HP-101, Identification and Reporting

of Radiological

Events,

Revision 4, required that the licensee

document

events

reportable

to the

NRC.

However,

other deficiencies,

such

as

failure to follow radiation protection

procedures

were not required to be

documented

on

a radiological

event report

(RER).

The licensee

revised

HP-101 in August 1989.

The inspectors

reviewed the revised

procedure

and

determined

that the licensee

had specified

requirements

for documenting

radiological

program inadequacies

and poor work practices.

The inspectors

reviewed

selected

radiological

event reports

made in 1990

and verified

that the licensee

was taking corrective action measures

for the identified

program inadequacies.

No violations or deviations

were identified.

Program for Maintaining Exposures

As Low As Reasonably

Achievable

(ALARA)

10 CFR 20. 1.c states

that

persons

engaged

in activities under licenses

issued

by the

NRC

should

make

every

reasonable

effort to maintain

radiation

exposures

as

low as

reasonably

achievable.

The

recommended

elements

of

an

ALARA program

are

contained

in Regulatory

Guide 8.8,

Information Relevant

to Ensuring that Occupational

Radiation

Exposure at

Nuclear

Power Stations will be ALARA, and Regulatory Guide 8.10, Operating

Philosophy for Maintaining Occupational

Radiation

Exposures

ALARA.

The last time the licensee

had two refueling outages

in one year was

1987

and

the licensee's

collective

dose

was

448

person-rem

per unit.

The

licensee

had

a collective dose of'84.5 person-rem

per unit in 1988

and

231.5

person-rem

per unit in 1989.

The licensee

established

their 1990

collective dose

goal to meet

a three year average

aoal of 288 person-rem

per unit.

In order to meet that goal the licensee

would have to keep the

collective

dose total for 1990

below

692 person

rem.

The licensee's

estimate of collective dose for 1990,

based

on work planned

and historical

data,

was

748 person-rem.

Significant dose tasks for 1990 included Unit

1

steam generator

tube pull and plug tasks,

and reactor coolant

pump impeller

inspection

on Unit 2.

In efforts to increase staff involvement

in the

ALARA program,

the Plant

Yianager requested

each

department

head to develop

an action plan to reduce

their department

dose.

The

plans

were to

be

completed

prior to the

start of the Unit

1 outage.

However, the Unit

1 outage

began three

weeks

early

and most'lans

were

not

completed

or submitted.

The

ALARA

Coordinator

reported

that

the

licensee

had

established

a new'nnual

personnel

exposure

limit of 2,500 millirem.

The

ALARA coordinator

reported

that

the

lowered

administrative limit had

heightened

worker

attention to keep personnel

exposures

ALARA.'n

an effort to minimize primary system

general

corrosion rates,

reduce

deposition

and activation of corrosion

products

on fuel cladding,

and

therefore,

reduce

general

plant

dose

rate

source

term,

the licensee

had

previously

implemented

an elevated

lithium control

proaram in the reactor

coolant

system.

Although

some

source

term reductions

had

been

noted

during previous

outages,

the

licensee

planned

to

suspend

the elevated

lithium control

program

immediately in Unit

1

and during the next fuel

cycle in Unit 2.

This

change

back to

a coordinated

lithium/boron

pH

control

scheme

was

prompted

by recent

general

industry concerns

linking

elevated lithium levels'ith primary water stress

corrosion cracking.

Ouring the inspection,

the licensee

remained

below the estimated

weekly

dose projection.

However, at the

end of the inspection

the licensee

was

11 days behind schedule.

No violations or deviations

were identified.

Training and gualifications

The

inspectors

reviewed

changes

in the

licensee's

training

program,

policies,

and

goals

relating to the radiation protection

program

and

discussed

the

changes

with licensee

representatives.

The inspectors

verified that

the

changes

should

not adversely

affect the licensee's

program.

Prior to

being

allowed

to perform

unsupervised

health

physics

(HP)

technician

job coverage,

senior level

vendor technicians

were carefully

screened

by the licensee.

The guidelines for the screening

process

were

described

in a

recommended

practice entitled "Guidelines for Training and

gualification of ANSI Contract Health Physics Technicians."

This guidance

was developed

for

and

implemented

at both the St. Lucie and Turkey Point

sites.

The licensee

procedures

defined standard

duties for senior level

vendor technicians,

set

minimum experience

requirements,

and established

training

and testing requirements.

The inspectors

reviewed

and discussed

the program with cognizant plant personnel

and noted the following program

highlights:

The standard

duties of a senior level

HP technician

were

based

on

a

focused job/task analysis.

b.

Each

vendor senior technician

must pass

a written examination

based

on the

above

described

tasks.

The test

covered

basic

HP theory,

equipment

and

procedure

knowledge.

Minimum passing

score

was

80

percent.

Retesting

was at the discretion of the

HP Supervisor.

No

retesting

was allowed for a score of less that

60 percent.

Once

a

technician

passed

the test, retesting

was not required

as long as the

technician

had not been inactive for more than

one year.

c.

Technicians

were also trained

and tested

annually

on site specific

policies

and

procedures

with the

same pass/fail criteria

as

above.

Junior level

technicians

were not required to

be tested,

however,

they were not allowed to perform senior level tasks

unless

they were

directly supervised.

d.

A review of the lesson

plan developed for vendor technician training

showed it to be very comprehensive

and complete.

e.

Minimum experience

requirements,

using

ANSI/ANS 3. 1-1978

as

a basis,

were defined

in detail.

Resumes

of contract

HP technicians

were

verified by contacting at least

two of the individual's. prior work

sites.

f.

A selected

review of several

vendor qualifications

packages

found

them to

be complete.

These

packages

included test results,

resume

verification information,

and experience

evaluations.

The vendor

HP technician qualification and training program was considered

by the inspectors

to be

a licensee

strength.

No violations or deviations

were identified.

5.

External

Exposure Control

and Personnel

Dosimetry

The

inspectors

reviewed

the

licensee's

external

exposure

controls

including use of radiation

work permits

(RWPs), posting of radiological

areas,

access

controls for high radiation

and locked high radiation areas

(HRAs),

and

licensee

procedures.

The inspector

determined

that

the

licensee's

procedures

for controlling access

to

HRAs were inadequate,

in

that,

they

did

not

adequately

describe

the

licensee's

methods

for

controlling

and monitoring activities in high radiation

areas.

As

a

result the licensee

received

a violation for inadequate

procedures,

and

a violation for not adequately

securing

a locked

HRA, after inspectors

were

able to open

a "locked high radiation" gate.

Hi gh Radi ati on Areas

10 CFR 20.202 defines

a

HRA as

an area,

accessible

to personnel,

in

whi ch there exists radiation at levels

such that

a major portion of

the

body

could

receive

in

any

one

hour

a dose'n

excess

of

100 mi llirem.

10 CFR 20.203(c)(2)

requires

a licensee

who establishes

a

HRA to

control

each entrance

by one of three methods.

These include:

(1)

A control device that would cause

the level of radiation to be

reduced

below

100 millirem per hour

upon personnel

entry into

the area.

(2)-

A control

device

to notify persons

entering

the

area

and

licensee

supervision of the entry.

(3)

Maintain the

area

locked except

during periods

when access

to

the area is required, with positive control over each entry.

In lieu of the "control device" or "alarm signal"

requirements

of

10 CFR 20.203(c)(2),

licensee

Technical Specification (TS) 6.12

requires

that areas

having

dose

rates

greater

than

100 millirem per

hour but less

than 1,000 millirem per hour be conspicuously

posted

as

a

HRA and

access

controlled

by use of a

RWP.

Additionally, persons

permitted to enter

such

areas

shall

be provided with or accompanied

by one of the following:

(1)

A radiation monitoring device which continuously indicates

the

dose rate in the area.

(2)

A radiation monitoring device which continuously integrates .the

radiation

dose

rate in 'the area

and alarms

when

a preset

dose

is received,

or

(3)

A

HP qualified individual with

a

dose rate monitoring device,

who is responsible

for providing positive control

over the

activities within the

area,

and

who shall

perform periodic

radiation surveillance at the frequency specified

by the facility

Health Physicist

on the

RWP.

TS 6. 12.2 requires

that

each

HRA accessible

to personnel,

in which

there exists

radiation at levels

such that

a major portion of the

whole

body could receive,

in any

one

hour,

a

dose

in excess

of

1,000 millirem,

be

secured

to prevent

unauthorized

entry.

The

requirement

states

the following:

(1)

That

areas

having

dose

rates

greater

than

1,000 millirem per

hour

(mrem/hr)

shall

be

locked to prevent

unauthorized

entry

with keys controlled by licensee

supervision.

(2)

Doors

shall

remain locked

except

during

access

by personnel

under

an approved

RWP which shall specify the dose rates in the

area with maximum allowable stay times for individuals in the

area.

(3)

In lieu of the stay time specification of the

RWP, direct or

remote

(such

as

use of closed circuit TV cameras)

continuous

surveillance

may

be

made

by personnel

qualified in radiation

protection

procedures

to provide positive

access

control

over

activities within the area.

(4)

Individual areas

accessible

to personnel

with radiation levels

such that

a major portion of the body could receive in one hour

a

dose

in excess

of 1,000 millirem, that are located in large

areas

such

as containment

where

no enclosure exists for purposes

of locking and

no enclosure

can

be reasonably

constructed

around

the individual areas,

shall

be

roped off, conspicuously

posted

and provided with a flashing light as

a warning device.

TS 6. 11 requires that procedures

for personnel

radiation protection

be consistent with the requirements

of 10 CFR Part 20 and

be approved,

maintained,

and

adhered

to for all operations

involving personnel

radiation exposure.

Over

a

three

day

period,

inspectors

observed

work in Unit

1

Containment Building and in the Unit

1 and

2 Auxiliary Buildings.

On

February 26,

1990,

while performing radiation

and

high radiation

surveys

in the Unit

1 Containment Buildino, the inspectors

were able

to open

a gate

leading to

a locked

HRA.

The inspectors

entered

a

HRA boundary

and

observed

a radiation level of 400 mrem/hr at the

surface

of

a locked

gate

leading to the Unit

1 Regenerative

Heat

Exchanger

(RHEx) room.

With very little effort the inspectors

were

able to obtain

an

18 inch wide opening in the

42 inch doorway,

by

repeatedly

pushing

on the gate

and raising the chain.

The inspectors

immediately notified the

HP Operations

Supervisor.

The

HP supervisor

made

a cursory survey inside the

RHEx room and then properly locked

the gate.

After

a brief investigation the

HP Supervisor

found that

the lock could only enter the outside links on each

end of the chain

and that the chain, if only wrapped

once

around the gate

and post,

would provide the

18 inch opening.

HP supervision

stated that

a memorandum identifying the problem

and

the correct method for locking the gate to the Unit 1

RHEx room would

be

issued

to all

HRA key holders

and further training would

be

provided.

The survey

performed

by the

HP supervisor

revealed

dose

rates of 200-1,700

mrem/hr at

18 inches

and 3,000 mrem/hr on contact

on the

RHEx.

The inspectors

informed licensee

management

that the

failure to sufficiently lock the gate to the

RHEx'oom to prevent

unauthorized

entry

was

an

apparent

violation

of

TS 6.12.2

(50-335/90-07-01).

During the inspection,

the inspectors

observed

a worker installing

a

snubber in a

HRA on the -5 foot elevation of the Unit

1 containment

building.

The worker was in a high radiation

area

working off the

floor in the overhead,

without

a radia'tion monitor.

When questioned

about the location of a monitoring device the worker stated that

he

had

a dose rate monitoring device

near the area.

The worker had to

leave his position in the overhead to obtain it.

The worker stated

that

HP had initially performed the area

survey

and then left.

The

worker was

aware of the dose rates

in the immediate

area

where

he

wa

workino.

The inspectors

observed

a similar situation in the Unit

1 Auxiliary

Building.

A worker

was

working

on

a ladder

in

a

HRA without

a

radiation monitor or

a

HP technician with

a monitor near

by.

The

inspector

determined

that the worker did have

a radiation monitor

a few feet

away at the

HRA boundary.

When questioned

about the dose

rates

in the area

where

he was working, the worker reported

the dose

rates

were nearly twice those

measured

by the inspectors.

The inspector notified

HP supervision of the events

and inquired

as

to what constitutes

periodic radiation surveillance or continuous

HP

job coverage.

HP supervision

at first stated

continuous

coverage

required direct

eye contact within voice control of the workers.

However,

a later definition

was

given

by

HP supervision.

That

definition basically stated that periodically

a

HP technician

should

visit the job site at his discretion

based

on the radiological

conditions at the job site.

The inspectors

questioned

HP technicians

in the containment building

and the auxiliary building as to what conditions

would exist before,

periodic job coverage

should

be changed

to continuous

coverage.

None

of the

answers,

when

provided

by the

HP technicians

showed

any

consistency.

The inspector

determined that the licensee staff was uncertain

as to

what continuous

coverage 'was

and

when it was to be applied

and that

the licensee's

procedures

provided

no guidance

on what activities

required

continuous

coverage.

HP

supervision

stated

that

HP

procedures

did not define periodic coverage

or continuous

coverage

required

by the

TS 6. 12.

Licensee

procedures

did not define periodic

radiation surveillance

requirements,

duties,

and responsibilities for

health physics

personnel

monitoring activities within HRAs.

The inspectors

reviewed

licensee

procedures

to determine

the type of

instruction that was provided

by the licensee for personnel

entering

HRAs.

Licensee

procedures

did

not

define

worker monitoring

responsibilities

within

high

radiation

areas,

when

radiation

" monitoring devices

were

issued

for purposes

of meeting

TS

6. 12

requirements.

'

Failure to

approve

and

maintain written

procedures

addressing

radiological

protection

requirements

for activities

in

HRAs

as

required

by licensee

TS 6.12

was identified as

an apparent violation

of licensee

TS 6. 11 (50-335/90-07-02)

The

inspectors

identified additional

procedural

weaknesses

which

included:

o

Lack of guidance

or defini tion of what constitutes

an acceptable

barrier for meeting the requirements

of TS 6. 12.2.

Lack of guidance

concerning

acceptable

uses of flashino warning

lights used in meeting

access

control requirements

of TS 6. 12.2

for areas

impracticable to lock.

Licensee

representatives

acknowledged

procedural

inadequacies

for

high radiation

areas

and

committed to develop,

approve,

and maintain

written procedures for HRA activities.

b.

Personnel

Honitoring

10 CFR 20..202 requires

each

licensee

to supply appropriate

personnel

monitoring equipment to specific individuals

and re'quire the

use of

such

equipment.

During tours of the plant, the inspectors

observed

workers wearing appropriate

personnel

monitoring devices.

The majority of personnel

entering containment

were observed

to place

their thermoluminescent

dosimeter

(TLD) and self-reading

dosimeter

(SRD) in

a clear plastic

bag

and tie it to the chest

area

on the

outside of the protective clothing.

However, workers performing floor

scabbling in the Unit 2 auxiliary building were working in a radiation

area

with paper

suits

over their

TLDs

and

SRDs.

The inspectors

informed

the

Health

Physics

Operations

Supervisor

that this

was

considered

to be

a poor radiological

work practice since it inhibited

the worker from frequently monitoring their

SRD without an increased

risk of contamination.

HP supervision

reported

that they would

evaluate this practice to determine if changes

were needed.

Two violations were identified.

6.

Internal

Exposure Control

10 CFR 20.103(b)

requires

the

licensee

to

use

process

or engineering

controls,

to

the

extent

practicable,

to limit concentrations

of

radioactive material

in air to levels

below that specified

in Part 20,

Appendix B, Table

1,

Column 1, or limit concentrations

when averaged

over

number of hours in any week during which individuals are in the area,

to

less

than

25 percent of the specified concentrations.

The use of process

controls

and engineering controls to limit radioactive

concentrations

in air was discussed

with licensee

employees

and controls

were

observed

in the Unit

1 Containment

and Auxiliary Buildinas.

The-

licensee

was also observed to use

containment

devices for work in highly

contaminated

areas

and drip containers

on valves with radioactive leaks.

10 CFR 20. 103(b)

requires that

when it is impracticable to apply process

or engineering

controls to limit concentrations

of radioactive material in

air

below

25

percent

of the concentrations

specified

in Appendix 8,

Table 1, Column 1, other precautionary

measures

should

be used to maintain

the

intake

of radioactive

material

by

an

individual within seven

consecutive

days

as far below 40 NPC-hours

as is reasonably

achievable.

10 CFR 20. 103(c)

(2) provides that the licensee

may make allowances for

the

use

of respiratory

protection

equipment

in estimating

exposures

of

individual to radioactive material

in air provided the licensee

maintains

and

implements

a respiratory

protection

program that

includes,

as

a

minimum,

written

procedures

reaardino

supervision

and

training

of

personnel

and issuance

records.

The inspectors

reviewed the licensee's

procedures

for use of supplied air

respirators.

The

inspectors

observed

that

breathing

air mainfolds,

pressure

gauges,

and

carbon

monoxide

monitors

inside

containment

were

calibrated

and workina properly.

Breathing air was currently in use in

the steam generator

cubicles

and

on the refueling floor for reactor vessel

cavity cleanup.

No violations or deviations

were identified.

Surveys, Nonitorina,

and Control of Radioactive Naterial

10 CFR 20.201(b)

requires

each

licensee

to make or cause

to be

made

such

surveys

as

(1) may

be

necessary

for the licensee

to comply with the

regulations

and

(2) are reasonable

under the circumstances

to evaluate

the

extent of radioactive

hazards

that may be present.

The

inspectors

reviewed

the

plant

procedures

which established

the

licensee's

radiological

survey

and monitoring program

and verified that

the procedures

were consistent

with reaulations,

Technical Specifications

and good Health Physics

(HP) practices.

The inspectors

reviewed

selected

records

of radiation

and contamination

surveys

performed

during the period of January

and

February

1990,

and

discussed

the survey results with licensee

representatives.

During tours

of the plant, the inspectors

observed

HP technicians

performina radiation

and contamination

surveys.

The

inspectors

performed

independent

radiation

and

loose

surface

contamination

surveys

in the Auxiliary and Unit

1 Containment Buildings

and verified that the areas

where properly posted.

The inspectors

discussed

with the licensee

the methods

used to release

material

from the restricted

area

and

observed

technicians

performing

release

surveys for material.

No violations or deviations

were identified.

Hot Particle Control

Program

The inspector:

discussed

the hot particle control

program with a cognizant

licensee

representative

and

reviewed

the

licensee

procedures

that

described

the control program

and dose

assignment

methodology.

Known and potential

hot particle

zones

were identified by procedure

and

required

additional

survey

and worker requirements

including additional

protective

clothing,

continuous

HP coverage,

and

trash

and

equipment

removal

techniques

when work was being done in these

areas.

Areas

were

surveyed for hot particles

using

gross

masslin

mopping or

wiping and using

a paint roller type device with sticky tape that would be

rolled over

a floor or other surface.

The masslin cloth

and the paint

roller would

then

be

surveyed directly for hot particles

or any other

significant contamination.

The documented

results of these

surveys

would

be identified as

a "Hot Particle Survey."

The radiation

dose

to the

skin from particles/skin

contamination

was

computed using the acceptable

VARSKIN computer code.

Ouring the Unit

1

outage,

strippable

paint

had

been

applied

to the

surfaces

of the reactor cavity prior to cavity flood-up for refuelino

operations.

The licensee

was very enthusiastic

about

the

use of these

coatings

in that

previous

experiences

had

resulted

in significant

reductions

in contamination

levels

and

dose

rates

in the cavity after

draining

and

removal of the coating from the walls and floor.

The use of

underwater

vacuums to remove crud from the floor of the cavity also greatly

assisted

in these

reductions.

No violations or deviations

were identified.

Licensee Actions on Previously Identified Inspector Findings

(Closed)

IFI 50-335/89-01-02:

This item concerned

the establishment

and

implementation

of criteria for initiating investigations

of radiological

protection

program deficiencies.

The inspectors

verified that criteria,

for performing investigations

of program deficiencies,

were incorporated

into written procedures

and

they also

reviewed

selected

Radiological

Event Reports.

The IFI is discussed

in Paraaraph

2.

(Closed)

IFI 50-335/89-19-01:

This

item

concerned

the

licensee's

procedure for estimating radioactivity of material

from direct radiation

measurements

made with survey

instrumentation.

The inspector verified

that

the

licensee

had

provided

guidance

in written

procedures

for

'

¹

selecting

appropriate

equations

when estimating radioactivity from direct

radiation surveys.

The licensee

also revised

procedure

forms to improve

documentation

of the calculated results.

Exit Interview

The inspection

scope

and findings were

summarized

on March 2, .1990, with

those

persons

indicated

in Paragraph

1 above.

The inspectors

described

the areas

inspected

and discussed

in detail the inspection findings and

a

violation (50-335/90-07-01) listed below.

At the exit meeting,

the

inspectors

notified licensee

management

that

their procedures

for access

controls

and monitoring requirements for HRAs

was

a program weakness.

The licensee

acknowledged

deficiencies with their

written procedures for controlling assess

to HRAs.

The licensee

committed

to reviewing

and

revising

licensee

procedures

to better

define

high

r'adiation

area

control policies

and requirements.

Upon further review of

the activities identified during the inspection the inspectors

determined

that

a lack of procedural

guidance in written instructions

was

a violation

of TS 6. 11.

During

a telephone

conversation

on March 15,

1990,

between

J. Potter

and

R.

B. Shortridge of the

NRC and

H. Buchanan of Florida Power

and Light, the licensee

was informed that failure to have adequate

written

procedures

for controlling activities

in

HRAs

was

a

violation

(50-335/90-07-02)

of TS 6. 11.

Dissenting

comments

were not received

from

the licensee.

The inspectors

reported that the licensee's

policies

and

procedures

for qualifying vendor

HP personnel

was

a program strength.

The

inspector

also

reported

that

the licensee's

collective

dose

goals for

meeting three year industry averages

was aggressive

and
