~ f Provide a detailed description of the onsite storage facility for the
.replaced steam generator lower assemblies.
Include a description of all systems designed to minimize the spread of radioactivity (e.g.,
floors, sumps, air filtration units}..
2; Provide a description of the proposed surveillance requirements for the steam generator lower assemblies.
Describe the methods to be
~.used to monitor airborne and liquid releases to the environment from the storage facility.
Describe the monitoring program to be used to assure the integrity of the seals on the steam generator openings'and that the external surface contamination remains below acceptable levels.
Include the proposed surveillance frequency for the above monitoring
- programs, 3.
Provide a description of the methodology of determining surface con-tamination levels on the replaced steam generators.
Provide the cri-teria used for determining if the external surfaces of the steam gen-erators must be decontaminated.
If the steam generators are to be stored in an open facility (e.g.,
open roof or earthen floor), it is the staff's position that external. loose and fixed surface contamination should be reduced to a minimum, A level acceptable to the staff is the contamination level given in Table 1 of Regulatory Guide 1.S6.

assurance that (1) the external surfaces of the steam generators wil1 be decontaminated to acceptable
- levels, (2) the surface activity will be adequately contained or (3) justification for allowing surface con-tamination levels in excess of Regulatory Guide 1.86 for open storage of the generators.

- 4. If you elect to store the steam generators in a facility which is open to the environment (e.g.,
no roof), provide an estimate of the occupa-tional exposure necessary to decontaminate the external surfaces to the levels specified in the previous question.
In addition, provide estimates of liquid and gaseous effluents and volumes of solid waste generated during the decontamination.
Provide justification that. the decontamination and.storage in an unenclosed storage facility will keep radioactive effluents and occupational radiation exposures "as low as reasonably achievable" when compared to storage in an enclosed storage facility.

Section 5.2.2 of the Turkey Point "Steam Generator Repair Report" gives the estimated radioactive releases from the repair effort.
Do these releases include expected releases
-from fuel movement activitiesp If not, provide the additional releases to the environment resulting frc.
fuel handling operations.
- 6. It is the staff's position that s'ignificant amounts of Fe-55 and Ni-63 may be released during the steam generator repair effort. It is our position that you (1) commit to perform a monthly composite sample of all liquid effluents for Fe-55 and Ni-63 or (2) provide adequate justi-fication for not monitoring for. these isotopes.
