10 CFR PART 21 NOTIFICATION - CARBOLINE COMPANY

The following information was obtained from the vendor via facsimile:

"This letter serves to notify the Commission of a potential safety related noncompliance deviation in a basic component as defined in 1OCFR Part 21. The noncompliance involves hard settling of Carboguard 890 Part B; the affected batches are 2A9266L, 2A9275L, and 2H9352L.

"The hard settling of Carboguard 890 Part B would result in a mixed product that would have lower pigment volume concentration (PVC) than standard material that has been uniformly dispersed. Potential deficiencies would be a lack of film build during application as a result of a lower initial viscosity and the fact that some particles from the hard settling may have been dispersed into the mixed product. These particles could result in the clogging of spray gun tips or having particles embedded into the applied coating, which are aesthetically unpleasing. Overall the lack of pigment in the coating film affects the application and aesthetic properties of the coating and not the performance properties. The primary criteria for the epoxy coating's performance are that the stoichiometry of epoxy resin to amine curing agent are not changed by more than 10%. Based upon a prior non-nuclear occurrence we know that the hard settling does not alter the stoichiometry of the coating and the cure of the product will be within the parameters designed by the formulating chemist. Based upon prior testing of numerous coatings for use in nuclear power plants we have not seen any detrimental performance when lower PVC coatings were evaluated. Resin rich coatings are typically gloss coatings and they aid in radiation decontamination and chemical resistance. As such, Carboline does not feel that the performance of the coating will be adversely affected.

"A database has been created documenting all shipments of the affected batches made within the 2002 calendar year to present; approximately 30 utilities/customers are affected. All customers who our records indicate have been shipped batches 2A9266L, 2A9275L, and 2H9352L shall be notified promptly. We are requesting that customers review their stock of Carboguard 890 Part B and return the affected batches for replacement.

"In summary, Carboline has taken appropriate corrective action, notified the NRC, and shall notify all customers promptly."

This letter serves to notify the Commission of a potential safety related noncompliance deviation in a basic component as defined in lOCFR Part 21. The noncompliance involves hard settling of Carboguard 890 Part B; the affected batches are 2A9266L, 2A9275L, and 2H9352L

The hard settling of Carboguard 890 Part B would result in a mixed product that would have lower pigment volume concentration (PVC) than standard material that has been unforraly dispersed. Potential deficiencies would be a lack of film build during application as a result of a lower initial viscosity and the fact that some particles from the hard settling may have been dispersed into the mixed product. These particles could result in the clogging of spray gun tips or having particles embedded into the applied coating, which are aesthetically unpleasing. Overall the lack of pigment in the coating film affects the application and aesthetic properties of the coating and not the performance properties. The primary criteria for the epoxy coating's perforrnance are that the stoichiometry of epoxy resin to amine curing agent are not changed by more than 10%. Based upon a prior non-nuclear occurrence we know that the hard settling does not alter the stoichiometry of the coating and the cure of the product will be within the parameters designed by the formulating chemist.

In sumrnary, Carboline has taken appropriate corrective action, notified the NRC, and shall notify all customers promptly.
