Qualification Test Results AEC&83/0047 l The Nuclear Environmental Qualification Test Program for the Grand Gulf Nuclear Stetlon (GCNS) Hydrogen Igniters has been successfully completed and the igniter assemblies are considered fully qualified. The qualification program met the requirements of IEEE 323-1974 and NUREG-0588 and complies with the commitments of References 1 and 2.

The attached Nuclear Environmental Test Report and the FUREG-0588 Equipment Evaluation Worksheet with supporting information provide complete l

documentation on the test program and resu hJ.

1 The successful qualification of the GCNS igniters removes the license l condition referenced on page 22-5 of Supplement #3 of the GGNS Safety Evaluation Report. No additional testing for qualification of the igniters is planned.

Should you have any questions concerning either the qualification program or the results, please contact :.:s.

Yours truly, L. F. Dale Manager of Nuclear Services JRH/SHH/JDR: sap Attachments ..

The only croponent exposed to beta radiation is the cover plate gasket.

This gasket is 1/8 inch thick and about 1 inch wide and oriented so that only the edge is exposed to beta radiation Due to the slight enount of penetration by beta into the gasket the function of the gasket will not be affecttd .
