20006 REQUEST FOR ADDITIONAL INFORMATION INFORMATION NEEDED TO EVALUATE TOPIC VI-1, "ORGANIC MATERIALS AND POST ACCIDENT CHEMISTRY" The following infonnation is necessary to complete our evaluation of this topic:
- 1. Estimate. the areas and thicknesses of the major protective coating systems inside containment, including aluminum and zinc base pa in ts, epoxy paints, acryl i.c 1 acquer, etc.
- 2.
Indicate whether these coatirig systems and their methods of application were qualified according to the recorrrnendations of Regu.latory Guide 1.54.
- 3. If not, describe the QA provisions which were used to assure proper application.
- 4.
For coatings not qualified with Regulatory Guide 1.54, describe the present condition of the coatings, including estimates of" the amounts of flaking, peeling, cracking, bubbles, etc. *
- 5.
Estimate the quantity of other miscellaneous coating materials.
(such as on snubbersj not qualified according to Regulatory Guide 1,54.
- 6.
Estimate the types and amounts of other organic materials such a~ electrical insulation inside containment.
- 7.
In addition to the information described above for organic coating systems, we will need the following information with respect to the related topic VI-5, "Combustible Gas Control":
Estimate the surface area and thickness of aluminum, iinc and
- galvanized steel inside *containment.
We have reviewed the infonnation available in the docket files for.
some of the SEP plants and found that the information described above was not available.
Since this topic is a fairly recent addition to the review areas for CP's and OL's, we do not expect*
to find the information in any of the SEP plant ~ocket material.
Accordingly, you are requested to provide the information described".
