NUCLEAR REGULATORY COMMISSION

OFFICE OF NUCLEAR REACTOR REGULATION

WASHINGTON, D.C. 20555 August 1, 1997 NRC INFORMATION NOTICE 97-59: FIRE ENDURANCE TEST RESULTS OF

VERSAWRAFP FIRE BARRIERS

Addressees

All holders of operating licenses or construction permits for nuclear power reactors.

Purpose

The U.S. Nuclear Regulatory Commission (NRC) is issuing this information notice to alert

addressees to the preliminary results of a recent fire endurance test of a new fire barrier

system. No specific action or written response is required.

DescriDtion of Circumstances

Transco Products, Incorporated, of Chicago, Illinois, is developing Versawrap as a

stand-alone fire barrier or as a potential upgrade for such existing raceway fire barriers as

Thermo-Lag 330-1 for use in nuclear power plants to meet NRC fire protection regulations.

On April 7, 1997, the NRC staff met with Entergy Operations, Incorporated, the licensee for

Arkansas Nuclear One, to discuss the use of Versawrap fire barriers to protect redundant

post-fire safe shutdown components. Subsequently, on April 10 and 11, 1997, the NRC staff

witnessed a full-scale fire endurance test of proposed 1-hour and 3-hour fire-rated Versawrap

fire barriers at Underwriters Laboratories, Incorporated (UL), of Northbrook, Illinois. The tests

were also witnessed by representatives of Entergy Operations, Incorporated, and Northern

States Power Company.

The following summary of the test results is taken from the staffs trip report:

Assuming that the thermocouples were working properly and on the basis of

the printed temperatures at the end of about 61 minutes, it appeared that test

articles A, B, C, D, L, 0, and R met the maximum single point temperature rise

acceptance criteria [of Generic Letter (GL) 86-10, Supplement 1, "Fire

Endurance Test Acceptance Criteria for Fire Barrier Systems Used to Separate

Redundant Safe Shutdown Trains Within the Same Fire Area'] for a 1-hour fire

rating while test articles E and Q did not. Assuming that the thermocouples

were working properly and on the basis of the printed temperatures at the end

of about 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and 55 minutes (the temperatures at 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> were not

IN 97-59 August 1, 1997 printed), it also appeared that test articles F, G, H, and I may meet the maximum

single point temperature rise acceptance criteria of GL 86-10, [Supplement 11, for a

3-hour fire rating, but test articles J, K, M, N, and P will not.

The observations made by the NRC staff during the fire endurance test are not sufficient in

and of themselves to determine whether or not Versawrap fire barriers will meet NRC criteria

for qualifying fire barriers. In Ks trip report, the staff also noted that UL would document the

results of the fire endurance test and that UL would base its conclusions regarding the

performance of the test articles on its observations during the fire endurance and hose

stream tests, analyses of electronically recorded thermocouple data, and consideration of

both the maximum single point temperatures and the average unexposed side temperatures.

Review and assessment of each of these factors are needed to determine whether the barrier

configurations that were tested meet the NRC acceptance criteria specified in GL 86-10,

Supplement 1. To date, no licensee has submitted the fire test results to the NRC for review.

The staffs meeting summary and trip report are available at the NRC Public Document Room

(Accession Numbers 9704188084 and 9705130324, respectively).

This information notice requires no specific action or written response. If you have any
