Docket No. 2-358 Cincinnati Gas and Electric Company ATTN:
Mr. Earl A. b rgmann Senior Vice President Engineering Services and Electric Production 139 East 4th Street Cincinnati, 011 45201
~
Gentlemen:
This refers to the telephone conversation between you and Mr. P. A. Barrett of our staff on September 3, 1980, regarding potentially deficient fire stop material manufactured by Tech-Sil Inc.
Based on the results of our continuing investigation of allegations involving Tech-Sil Inc., your contractor at Zimmer, we have determined that some of their products are not in conformance with project and NRC requirements. The following findings were made:
1.
The leaded elastomer seal material was tested for fire resistance in accordance with ASTM E-119 Appendix A, entitled "Three Hour Fire Barrier." Subsequent to the fire tests, the formula for the sealant was changed on January 2, 1979, on June 5, 1979, and again on September 10, 1979.
Fire tests were not conducted on the leaded elastomer seal material after any of these formula changes.
2.
liigh density
_icone gel seal material was tested in accordance with ASTM E-li:s on March 24, 1980.
The formula for the gel material was subsequently changed. Fire tests were not conducted on the gel after the formula changes.
3.
Certificates of conformance of the materials shipped to the site do not indicate that changes have been made in material formula since the fire tests were performed.
Consequently, nonconforming condi-tions apparently exist in various locations where this material was used in that fire tests were not performed.
Based on the above, we understand that you will discontinue with installa-tion of leaded elastomer and high density silicone gel penetration seals until the following actions have been completed.

b.

c.
Identify and report to us the circumstances which apparently
]
precluded your discovery of these conditions and include in your written report such corrective actions as are necessary in regard to your QA program and technical management of these activities.
