Dear Mr. Schwencer:
This letter and the attached test report is provided in response to License Condition No. 7.
Pennsylvania P~gpgpr 6 Light Company has conducted an ASTM E-119 test of the as-installed one hour cable wrap configuration at Southwest Research Institute test facilities.
Testing was conducted in accordance with Pennsylvania Power
& Light Company Specification No. F1001 with the exception of deviations as noted in the test report.
In order to complete the test program by a date supportive of our schedule to satisfy NRC requirements, the main test set up was tested when the sample had cured for thirteen days rather than the 30 days curing recommended by the manufacturer.
We believe the shortened curing time did not influence the results of the testing of the Susquehanna specific configurations.
Circuit integrity of all monitored cables remained intact throughout the fire endurance portion of the test.
There were no short circuits and there was no loss of continuity in any of the circuit-to-system monitored cables.
However, during the hose stream portion of the test, circuit-to-circuit integrity was lost in several monitored instrumentation cables.
The failed instrumentation cables were in air drops and a ladder type cable tray. It
- should, however, be noted that neither, of the failed configurations exist for instrumentation cable at Susquehanna SES in areas where the tested fire resistive wrapping material is utilized.
Attached is Southwest Research Institute Test Report No. 01-7163.
We believe the test results demonstrate the adequacy of the tested wrapping material for 8208300285 820825
