Exit Interview

The inspection scope and findings were summarized on August 2, 1985, with

those persons indicated in paragraph 1 above. Two violations were discussed

with licensee management. One violation was for failure to follow written

procedures as required by Technical Specification 6.5.1.1.1 and the other

involved a failure to take an appropriate air sample as required by

10 CFR 20.103(a)(3). Both violations were a result of work performed on the

incore detectors in the seal table room of reactor containment.

Licensee

management took no exceptions. The licensee did not identify as proprietary

any of the materials provided to or reviewed by the inspectors during this

inspection.

(Closed) Violation (50-261/84-10-04) Labeling of containers with radioactive

material labels. The inspector reviewed and verified the corrective actions

stated in Carolina Power and Light Company's (CP&L) letter of June 1, 1984.

(Closed) Unresolved Item (50-261/85-09-01) Radiation exposure received by a

visitor without completing General Employee Training (GET).

The inspector

reviewed and verified the corrective actions taken by the licensee which

included a procedure revision to DP-001,

Dosimetry Issuance, controlling

radiation exposure received by each visitor to less than 100 mrem in a year.

No violations or deviations were identified.

(Closed) Violation (50-261/85-09-02)

Unauthorized entry into high radiation

areas > 1000 mrem/hr.

The inspector reviewed and verified the corrective

actions as stated in CP&L's letter of March 29, 1985.

4.

Significant Event During Entry to the Seal Table Room (93711)

Through reviews of

licensee records and discussions with licensee

representatives the inspector determined the following:

a.

On the morning of July 16, 1985, two individuals entered the seal table

room to do preliminary work on incore detector system using a routine

radiation work permit (RWP) 4012. The work was unsuccessful and they

exited the area. Subsequently, the licensee determined that a second

entry would be made to 1) correct the problem in "C" 5th path incore

detector drive system and 2) replace the "D" incore detector.

A

radiation control (RC)

technician was assigned the responsibility for

job coverage by the RC foreman and was told that the foreman would be

in the area to direct activities. The RC technician looked at previous

surveys for the area and noted that general radiation levels around the

"C" detector box was 50 mR/hr with smear surveys of 130,000 dpm/100

cm2 . At 1:35 pm six individuals entered the seal table room to change

out the "D" incore detector.

An Instrumentation and Control (I&C) foreman and RC foreman were on the

scene directing the activities of their personnel.

A qualified health

physics (HP) technician was there to perform necessary surveillance of

the work.

When the maintenance personnel opened the cabinet that

contained the cable and associated couplings, dose rate measurements

revealed 200-300 mR/hr towards the back of reel and about 400 mR/hr

general area.

Because of concern with the radiation levels,

no

contamination surveys were taken.

Upon exiting the area the individuals discovered facial and nasal

contamination on their person. The individuals were immediately taken

to dosimetry for whole body counting. Preliminary results indicated

that they all had inhaled radioactive contamination

and that the

maximum exposed individual contained 80% of a maximum permissible organ

4

burden in the upper gastrointestinal (GI)

tract.

A more complete

analysis of this individual on 7/17 revealed the following activities:

b.

Technical Specification 6.5.1.1.1 requires that written procedures be

established, implemented and maintained covering applicable procedures

recommended in Appendix A of Regulatory Guide 1.33, Rev. 2,

February 1978.

Appendix A Regulatory Guide

1.33 states that the

licensee should

have radiation protection procedures governing a

radiation work permit system, and respiratory protection.

Plant Programs Procedure PLP-16,

Radiation Work Permit (RWP)

Program,

required an

RWP to be written for a specific task.

Health Physics

Procedure HP-006, Section 5.6, Control of Internal Dose, required that

respiratory protection or stay times be utilized to maintain internal

exposures "As

Low As Reasonably Achievable"

(ALARA).

The inspector

reviewed Radiation Work Permit (RWP)

4012,

surveys, qualifications of

the personnel performing the work and training of the individuals

involved. A review of the RWP revealed that a general (non

specific

RWP) RWP was used to control the activities of the work.

Failure to use a specific RWP for the seal table work as required by

Plant Procedure PLP-16 was identified as an apparent violation of

TS 6.5.1.1.1 (50-261/85-24-02).

Discussions with licensee representatives indicated that there were no

contamination surveys taken inside the detector cabinet prior to the

work. Post event followup surveys revealed contamination levels in

excess of 2 million dpm per 100 cm2 . An analysis of these levels prior

to the work would have indicated that respiratory protection should be

considered to maintain exposures ALARA.

Failure to use respiratory

protection or stay times to maintain internal exposures ALARA was

identified as another example of an apparent violation of Technical

Specification 6.5.1.1.1 (50-261/85-24-02).

c.

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 in this part,

and (2)

are reasonable under the

circumstances to evaluate the extent of radiation hazards that may be

present.

10 CFR 20.201(a) defines "survey"

as an evaluation of the

radiation hazards incident to the production, use, release, disposal,

or presence of radioactive materials or other sources of radiation

under a specific set of conditions.

When appropriate, such evaluation

5

includes a physical survey of the location of materials and equipment,

and measurements of levels of radiation

or concentrations of

radioactive material present.

10 CFR 20.103(a)(3) requires the licensee to use suitable measurements

of concentrations of radioactive material in air for detecting and

evaluating airborne radioactivity in restricted areas.

The inspector reviewed the airborne radioactivity survey records and

noted there were no airborne radioactivity measurements taken in the

breathing zone of the workers either before, during or after the

detector replacements.

Failure to make appropriate airborne radioactivity surveys to evaluate

the hazard present

was

identified as

an apparent violation of

10 CFR 20.201(b).

(50-261/85-24-01)

The inspector reviewed the results of the analysis performed for the

positive counts that were related to the seal table incident.

The

inspector discussed the assessments and corrective actions with the

supervisor of the Instrumentation and Control technicians that had

positive counts.

The inspector also reviewed the MPC-hours for the

seal table incident and discussed action taken for all staff receiving

greater than 40 MPC-hrs in one week.

The inspector had no further

questions.

5. Training and Qualifications (83723)
