Advanced Planning for Refueling The inspector inquired as to preparations for refueling in terms of manpower, supplies, instruments, anti-C clothing, and planning related to dose reduction on certain jobs.

A licensee representative stated that about 70 " rent-a-techs" were hired to supplement the permanent plant Health Physics (HP) staff.

The 15 permanent HP technicians were assigned specialized job functions and the " rent-a-techs supplied the shift and job coverage.

The full staff was on site by January 7, 1981, prior to full refueling operations.

Containment entries during refueling averaged 1500 per day resulting in heavy use of Anti-C clothing.

Since the plant laundry is inadequate to handle this load, a laundry service was contracted for and was in operation on site during the inspection.

The contract laundry was able to process up to 3,000 coverr.11s per day.

The inspector reviewed the laundry operation and no problems were identified.

The licensee stated further that workers assigned to steam generator tube plugging used a mock-up on the turbine deck to training for the job and thereby reduce anticipated man-rem.

ANO personnel exposures for 1981 are approaching 550 man-rem for 1981,

-

due primarily to refueling operations.

The licensee stated that this refueling involved several high man rem jobs that are not usually performed.

-3-The inspector reviewed a exposure tabulation by Special Work Permit (SWP)

number and noted high man-rem for HP coverage, decon work, insulation and scaffolding work and steam generator repair.

The inspector noted that some portable instruments were in short supply, particularly friskers.

The licensee stated that additional portable instruments were on order and the frisker order would be expedited in order to receive them prior to Unit 2 refueling.

The inspector had no further questions in this area.

3.

R_adiation Protection Training The inspector reviewed selected training records pertaining to radiation worker and health physics technician training.

Interviews with selected persons was also conducted to determine the scope ano detail of training provided.

The review indicated compliance with 10 CFR 19.12 and ANO radiation protection training procedures.

I 4.

External and Internal Exposure Control The inspector reviewed the daily computer output that lists the accumulated weekly and quarterly external whole body exposures for each radiation worker.

The listings indicated that no worker has received an exposure in excess of 10 CFR 20.101(b; limits.

A review of permanent exposure records for selected workers indicated no discrepancies with respect to current and past radiation exposure documentation.

Records also indicate that exposure reports have been sent to terminating workers in compliance with 10 CFR 20.408.

The licensee has made limited use of MPC-Hour tabulations for workers since airborne concentrations during this outage has been quite low.

The i

HP icg indicated no significant personnel contamination incidents what would require evaluation of skin exposure.

Whole bcdy counting for workers is performed initially and at least annually thereafter.

A review of counting results indicated no internal exposures in excess of the 40 MPC-Hour control measure or the quarterly limit.

,

The inspector had no further questions in this area.

5.

Radiation Surveys l

The inspector reviewed the atrborne surveys taken to evaluate airborne activity for selected tasks inside containment during refueling.

The

'

l connection between SWP/RWP number and airborne survey is not presently made and it was difficult to determine the survey that supports the SWP/RWP recommendations.

Airborne survey records indicate date, building elevation l

and technical data.

The licensee stated that additional information would be provided on the survey sheet that would specify the SWP/RWP being evaluated and specific location information.

The inspector stated that this item would be considered open (50-313/81-07/01) pending completion of this action.

The inspector reviewed selected SWP/RWPs as to monitoring requirements.

It was noted that extremity and head monitoring was required on those jobs such as steam generator work that had some potential for exposure to these areas.

The head badge is worn outside the respirator and monitors skin and depth dose to head since the licensee was able to demonstrate that the respirator face piece was able to fully attenuate betaradiationexposuretgthelensoftheeye.

The ANO TLD badge contains 18 and 234 mg/cm filters to differentiate the shallow and deep dose components of exposure.

The inspector had no further questions in this area.

.

6.

Respiratory Protection The inspector reviewed the use of respiratory equipment during refueling operations.

The licensee makes wide use of respiratory equipment as a precautionary measure.

Required respirator use to limit worker exposure to w2ekly and quarterly limits has been limited.

The licensee presently uses only NIOSH approved equipment.

An individual's qualifications to wear respirators is verified by HP personnel at the controlled access point and the card is held until the equipment is returned.

The inspector noted that plant procedures do not require the use of a challenge atmosphere, such as irritant smoke, to provide a qualitative fit check prior to each use.

The inspector stated that this test is specified in NUREG-0041 and should be incorporated into and required by plant procedures.

This item is considered open (50-313/81-07/02) until action is completed.

The inspector has no further questions in this area.

7.

Access and Contamination Controls The inspector reviewed SWP/RWPs, protective clothing requirements, entries and exiting from radiation controlled areas, posting and labeling and movement of contaminated waste materials from radiation controlled areas.

The inspector noted that persons exiting the controlled access point were using the portal monitors, hand and foot :nonitor and the provided friskers.

l The licensee has initiated a color code system for contaminated trash and other materials inside controlled access but the final procedure has not been approved.

The inspector toured the Unit 1 and 2 auxiliary buildings and Unit 1 containment building on March 3, 1981.

The inspector noted improved housekeeping conditions since the Health Physics Appraisal (50-313/80-20).

Continuous Air Monitors (CAM) and the trash compaction area of Unit 1 continue to be problem areas.

Several CAMS were observed not working or in poor condition.

(50-313/80-20/28).

The large volume of trash to be compacted each day is too large for the space designated.

i

.The inspector had no further question in this area.

Procedure Review A selected review of revised HP procedures was made.

1602.01 Controlled Access Area Entry and Exit Procedure 1609.04 Radiological Respiratory Protection 1602.66 Marking and Handling of Contaminated Waste and Materials 1602.70 Radiation Exposure Control The need for ANO to develop and implement procedures in the health physics area has been previously identified (50-313/80-20/02).

ANO is now in the process of reviewing and changing over to a new set of procedures that were developed by a consultant.

The inspector noted in this inspection other health physics matters not adequately covered by present procedures.

These were:

Instructions concerning the reporting of dose information to terminating workers; instructions concerning beta dose to lens of the eye and use of protective goggles; criteria for tabulating and use of MPC-Hour exposure information; and instructions concerning the level of authority required for HP SWP/RWP approval.

The licensee stated that these items are addressed in their new procedures to be implemented about July 1981.

The inspector had no furthe questions in this area.

9.

Exit Interview The inspector met with AP&L representatives (See paragraph 1) at the ANO site at the conclusion of the inspection on March 6, 1981.

The inspector i

summarized the purpose and scope of the inspection, and discussed the l

inspection findings.
