SCOPE: This reactive inspection was performed as a result of an allegation that the 6-inch thick silicone foam fire seals used at Salem Unit 1 are improperly rated. In conjunction with this inspection, a meeting was held at Portland Cement Association (PCA) in Skokie, Illinois to discuss the fire seal tests that PCA performed for BISCO.

1.
Allegation On June 17-18, 1985, aVendorProgramBranch(VPB)inspectionwas performed at Brand Industrial Services Inc. (BISCO) in Park Ridge, Illinois and a meeting was held at Portland Cement Association (PCA),
Construction Technology Laboratories in Skokie, Illinois. The purpose of this inspection and meeting was to followup on an allegation made by BISCO to the NRC that " Salem Nuclear Generating Station Unit No. 1, cannot possess test data to show that the plant's 6-inch silicone foam fire barrier penetration seals are rated at 3-hours."
In May 1985, the NRC had reviewed two fire stop test reports submitted by Public Service Electric and Gas Company (PSE&G) in connection with the allegation, and concluded that the allegation was unsubstantiated and resolved.
Subsequent to the NRC's evaluation, BISCO expressed technical disagree ment with the NRC conclusion. The purpose of this inspection was to review any documentation that BISCO may have to support their position 2.
Findings The NRC consultant reviewed the two fire test reports and verified that the details of both tests met the requirements of ASTM E-119 for three hour fire resistant barriers based on the following technical data.

PAGE 3 of 6 The test performed by SEMCO (A Division of Products Research &
Chemical Corporation) Glendale, CA, on June 28, 1976, used SEMCO PR-855 RTV silicone foam sealant in a concrete floor slab. The test performed by PCA used BISCO SF-20 foam in a concrete floor slab. Both tests were 3-hour tests witnessed by a pSE&G represent-ative.
The SEMCO test slab contained penetrations of 2-inch up to 6-inch diameter pipes with various cables and a 12-inch by 18-inch cable tray with PVC cables as requested by PSE&G. The furnace time / temperature curve exceeded the E-119 curve for the first hour and followed the curve there after. This would make the results conservative. The penetration seals remained intact and secure throughout the test and no smoke or flame broke through any of the the slab was 190*F (80*F above ambient)g on the unexposed side of seals.
The highest thermocouple readin The PCA test was performed on a floor slab with a 30" by 30" block-out containing two electrical conduits and a ladder type cable tray.
The blockout surrounding the conduits and cable tray was filled with BISCO SF-20 to a depth of 6-inches and dammed on both sides with fiber board.
The penetration components and general arrangements were as requested by PSE&G. The furnace temperature was in accord-ance with the ASTM E-119 curve.
Some cables of the unexposed side smoked between 74 and 83 minutes, but no other changes were observed in the three hour test.
The highest thermocouple reading was 215*F (135"Faboveambient).
In summary, the two tests representing the 6-inch Salem i seals met the requirements of E-119 with regards to the time / temperature curve, the temperature rise limit of 250*F for the unexposed surface and other details of the tests' behavior. The standard hose tests were not performed as they were not required by ASTM E-119 for penetration seals in floor slab tests.
During this inspection, discussions were held with cognizant BISCO representatives to determine what technical information BISCO possessed that would invalidate the Salem fire stop seal test reports. At no time during the discussions did BISCO representatives present any documented evidence in support of their allegation.
Rather, they indicated that their information concerning the Salem fire stop seals was furnished to them verbally by a person employed at Salem. The BISCO representatives also indicated that the sophistication of penetration sealing was not generally understood in the industry.
The thrust of the BISCO position appeared to be that American Nuclear Insurers (ANI) has higher standards 'or testing

The two fire seal test reports submitted by PSE&G concerning the 6-inch seals at Salem were discussed with the BISCO represen-tatives. A copy of the test performed on June 4, 1976, by PCA at the request of BISCO, was provided to the BISCO representatives by the NRC. BISCO indicated that they had no record of it because of a fire which destroyed many records. After reviewing the report, they agreed that the test results were authentic and that the 6-inch thick silicone foam seals had passed the time-temperature tests in accordance with ASTM E-119. The remaining BISCO concerns were that the hose test had not been performed and that the two tests cannot qualify all of the seals at a nuclear plant. BISCO did not offer any specific documented information on unacceptable seals at Salem.
A visit was made to the PCA laboratory on June 18, 1985 for the purpose of verifying whether or not PCA had performed the fire stop test identified in the report dated June 4, 1976. Observations were made of the test facilities and discussions were held with PCA representatives, including the Manager of Fire Research (MFR). After reviewing a copy of the June 4, 1976 Salem fire test report, the MFR indicated that the report was typical of tests performed by PCA in 1976. He then performed a record search and retrieved a PCA letter dated September 21, 1976, to BISCO, in which the June 4, 1976, Salem test was discussed. This letter indicated that the test was success-fully performed on June 4, 1976, in accordance with ASTM E-119.
3.
Conclusions Based on the inspection at BISCO and discussions with PCA representatives, the BISCO allegation was not substantiated.
BISCO presented no credible objective technical evidence to show that the Salem 6-inch silicone foam fire barrier seal tests were invalid. The PCA letter to BISCO dated September 21, 1976, verified that the tests were successfully performed at PCA in accordance with the ASTM E-119-73 standard.
Further, a review of the test reports conducted during the inspection confirmed that the test results met the requirements of ASTM E-119-73.
