Dear Sir:

The NRC was notified of a potentially reportable deficiency in the referenced telephone conversation. At that time, it was estimated that a determination of reportability would be made within thirty (30) days.

Due_to the extensive investigation and evaluation required, an Interim Report is attached. -It is now expected that this information will be finalized by June 28, 1984, at which time a complete report will be submitted.

Very truly yours, C.E L k &ge E. E. Van Brunt, Jr.

II. Appr,oach jro _and .Statys Of _Prgposed Resolution Bechtel engineering is currently corresponding with Bingham Williamette and reviewing the PVNGS FSAR to deterime reportability and technical- justification for corrective action. In the meantime, steps are being taken to conduct additional pump tests and to acquire more accurate test data.
