Dear Sir:

We previously reported in Reference (b) a potential 10CFR50.55(e) item to Region I regarding the seismic qualification of the Control Rod Drive Mechanism (CRDM) shroud. We provided Interim Reports on this item in References (c) and (d).

An additional report regarding this matter, including the information required by 10CFR50.55(e), will be provided by June 1, 1985.
