Enclosure REQUEST FOR ADDITIONAL INFORMATION FOR A RADIOI0 DINE PROTECTION FACTOR FOR CALLAWAY PLANT, UNIT 1 (50-483) TAC #60138

1. The Union Electric Company submittal indicated that canisters will not be exposed to or used in environments containing organic vapors and chemicals which could cause aging, poisoning, or desorption of adsorbed radionuclides.

Describe in general the methods and particular procedures which will be applied to prevent the use of GMR-I canisters in the presence of organic vapors and chemicals. This should include a discussion of.

l (a) organic vapors and chemicals of concern to GMR-I use at Callaway; , l (b) methods and procedures for detecting (sampling) and/or precluding the l presence of organic vapors and chemicals where GMR-I canisters are used (e.g., i identify general sampling procedures applied specifically for GMR-I canister l

! use; identify administrative procedures which preclude use or release of 1 organic vapors and chemicals in GMR-I use areas);

(c) related controls for other systems or operations, such as charcoal filter bed technical specifications, which can also limit GMR-I canister exposure to l organics.  !

l

2. Identify the specific procedure (s) which will control canister storage and  ;

indicate the range of temperature and relative humidity allowed in the storage i a rea.

4

3. Identify the specific plant and training procedures which will be l developed or modified to incorporate controls, restrictions, and use of GMR-I canisters. .

l l

l i 4 Describe how you will verify the effectiveness of this special  !

respiratory protection program. The following elements (or equivalent) should i

be considered

(a) weekly whole body counts for individuals using the GMR-I canister for radiofodine protection, i i

(b) for individuals who exceed 10 MPC hours, a whole body count prior to the

individual's next entry into a radioiodine atmosphere; (c) establishment of an uptake level beyond which further entry into a radiciodine atmosphere would be restricted, pending health physics evaluation (e.g. 70 nC1);

i (d) establishmer.t of a whole body count / survey data base to be used to evaluate the results of the program, identify additional necessary restrictions, or provide recomendations for reduced requirements.

5. Describe how the quality and function of the MSA GMR-I canisters will be  ;

verified by UEC. Since radioiodine breakthrough is not directly detectable by the user, it is the utility's responsibility to assure that canister performance and quality are fully adequate through such measures as verification of vendor quality control and quality assurance, and through i development of utility / site QA/QC procedures which provide a continuing assurance of canister quality.

(a) Include a general discussion of any vendor audits performed, or outline the basis of your acceptance of vendor QA/QC controls for GMR-I canisters.  !

l l (b) Cite general controls and procedures related to GMR-I canister QA/QC to be utilized at Callaway by UEC.

6. Describe the methods which will be utilized to reduce potential radiciodine levels to minimal levels in the Callaway work areas. This should I include a discussion of the utilization of engineering controls, reactor coolant cleanup / purification, degasification, decay schemes, and system and area decontamination. Long term efforts to avoid or alleviate radiciodine i problems, such as through fuel quality control programs, fission product trending, and other operational controls, should be briefly discussed.
