Dear Mr. Keppler:

Thia letter serves as the interim reoort pursuant to 10CFR50.55(e) on the deficiencies cowarning agreement between FSAR 71gure 8.3-6 (Diesel and Diesel Breaker Logic Diagrams) and the present diesel generator logic.

Mr. P. R. Pelke of your of fice was notit'ied February 16, 1584, by Mr. B. D.

Walrath of The Cleveland Electric Illuminating Company (CEI) that this problem i

was being evaluated. This discrepancy was identified during a safety system l functional capability review being performed for CEI.by GDS Associa :es.

This report contains a description of the deficiency, planned corrective action and the date for filing of the next report on this subject.

Description of Deficiency Figure 8.3-6 of the FSAR does not conforr to other FSAR requirements nor to I Drawing No. B-208-216. Two discrepancies identified are 'that the FSAR figure i does not include the logic for a diesel generator loss of excitation and the figure identifies two five-second delays whereas the design combines them into - '

a sing 12 five-second delay. Other. discrepancies ware also. identified and the

, possible safety ef fects are being investigated.

_ Corrective Action Gilbert Associates, Incorpoiated, our Architect / Engineer, is investigating the possible safety implications of the identified discrepancies. It will also be determined whether design changes to conform to the FSAR or a change to the FSAR to reflect the design are r . juired.

We will submit our next report on this subject by April '30, 19C4.

Please call if there are any questions.
