Dear Mr. O'Reilly:
Enclosed is our response to 'J. T. Sutherland's March 30, 1979, letter, RII:LLJ 50-259/79-7, 50-260/79-7, and 50-296/79-7, concerning activities at Browns Ferry Nuclear Plant which appeared to be in noncompliance with NRC requirements.
Me have reviewed the above inspection report and find no proprietary information in it.
Very truly yo'mrs, J. E. Gilleland Assistant Manager of Power Enclosure 7 905gyoqqg~

RESPONSE
TO INSPECTION REPORT RII:LLJ 50-259/79-7, 50-260/79-7, 50-296/79-7 J. T.
SUTHERLAND'S 'LETTER TO H. G, PARRIS DATED MARCH 30, 1979 Infraction A.
As required by 10 CFR 20.203(b),
each radiation area shall be conspicuously posted with a sign or signs bearing the radiation caution symbol and the vords:
CAUTION (or DANGER) RADIATION AREA.
Contrary to the above, on February 28, 1979, the licensee had not posted a radiation 'area located on elevation 565 feet in the Radvaste Building.
Radiation from the Fuel Cask Haste Tank was causing a
radiation area vith dose rates ranging from 40 mr/hr at contact to 2.5 mr/hr at S ft 'from the tank.
e
~Res ense Corrective Ste s Taken and Results Achieved The entire radwaste building vas posted a radiation area.
This method of posting had been in effect for several years and had been our interpretation that the posting of the building met the intent of the regulation for posting radiation areas.
The radwaste building area was checked and posted to meet the inspector's interpretation of the regulation for posting radiation areas.
Other areas of the plant vere also posted in accordance vith the inspector's interpretation.
Corrective Ste s to be Taken to Avoid Further Noncom liance In the future, radiationareas in the plant vill be posted in accordance vith the inspector's interpretation of the regulation for posting in radiation areas.
Date Full Com liance vas Achieved Full compliance vith the inspector's interpretation vas achieved on March 2, 1979.
Deficienc B.
As required by 10 CFR 20.203(f)(l) and (2) each container of licensed material containing quantities greater than those listed in Appendix C of 10 CFR 20 shall bear a durable clearly visible label identifying the radioactive contents and shall bear the radiation caution symbol and the words "CAUTION, RADIOACTIVE MATERIAL"or "DANGER RADIOACTIVE MATERIAL". It shall also provide sufficient information to permit individuals handling or using the containers, or working in the vicinity thereof to take precautions to avoid or minimize exposures.
10 CPR 20.203(f){3) specifies exceptions to the labeling requirements of 10 CFR 20.203{f) {1) and (2).
Contrary to the above, on February 26, 1979 the licensee had not labeled, with the appropriate'arnings and information, several containers of radioactive material located near Turbine Building Door 208 and one container of radioa'ctive material located near Turbine Building Door 191.
Assuming typical activation products and based on measured radiation levels,. the inspector estimated the containers contained activities in excess of Appendix C quantities.
The exceptions specified by 10 CFR 20.203(f)(3) did not apply.
~Res onsa Corrective Ste s Taken and Results Achieved The boxes discussed in this item contained equipment and tools that had been used in a recent outage on unit 1.
Health physics personnel surveyed each of the boxes and properly labeled and marked each box.
Corrective Ste s to be Taken to Avoid Further Noncom liance The outage director sent a memorandum to each of his foremen instructing r
them in the proper procedure for transporting boxes containing radioactive material out of C-zones.
He emphasized that health physics personnel must be contacted and the boxes properly labeled before moving them.
Health physics has also added a weekly check of boxes to their routine.
This routine will require health physics technicians to check any unidentified box throughout the plant for the presence of radioactive material.
Date Full Com liance was Achieved March 2, 1979 s
I I
Infraction C.
As required by Technical'pecification 6.3.D stated in part, each high radiation area in which the intensity of radiation is greater than 100 mrem/hr but less than 1000 mrem/hr shall be barricaded.
Contrary to the above, on March 2, 1979, the licensee had not barricaded the entrance, through Turbine Building Door 191, into a high radiation area where there were "general area dose rates of up to 500 mrem/hr and contact dose rates o6. certain components of up to 1000 mrem/hr.
~Res esse Corrective Ste s Taken and Results Achieved The high-radiation area was checked and the do'or closed 'and locked.
Corrective Ste s to be Taken to Avoid Further Noncom liance Several steps are either being taken or will be taken to eliminate this problem.
A routine check of all high-radiation area doors will be made twice a shift to ensure the doors are closed.
Long-range corrective action willconsistof installing door closers and a door alarm system.
Date Full Com liance Vas/Vill be Achieved For the routine check, March 2, 19F9; for door closers'nd alarm system, September 1, 1979.
