Dear.'dr. Youngblood:

F Attached'is our consolidated report of the recently coupleted engineer-ing -analyses regarding Containmenc Sump Performance as the recult of postul'ated debris accumulation following a loss of coolant accident.

As di,scussed in our meeting of June. 7, 1984, these analyses clearly l indicate that protective coatings inside containment need not be

safet'y related as they-have no safety significance. However, reaffirm-

' ing the commitment made' tio you 'in our June 7 meeting,- TUGCO will

, continue to apply these coatings using qualified naterials, qualified

,.1 applicators, and aoproved application procedures. In-process verifica-tion ~(inspection) Jof Ethe' coatings work will be accomplished by a craft group other'than the applicators. Appropriate documentation

~

will ' be naintained' f or surf ace' preparation,! Primer, and finish coat

, application to satisfy the coatings specification. Additionally, the craft application and inspection activities will be monitored by Engineering ,to ensure the objective'of an acceptable finished productzwitu tha dhsired corrosio'n protection and decontamination propertler . -

2 jWe plan to submit an amendments to our FSAE reflecting these changes (no later > th'an~- August, 1984. If you have gaestions, please call.
