James M. Taylor, Director, IE Robert B. Minogue, Director, RES John G. Davis, Director, NMSS Thomas E. Murley, Regional Administrator, Region I J. Nelson Grace, Regional Administrator, Region II James G. Keppler, Regional Administrator, Region III Robert D. Martin, Regional Administrator, Region IV John B.. Martin, Regional Administrator, Region V FROM:

C. J. Heltemes, Jr., Director Office for Analysis and Evaluation of Operational Data

SUBJECT:

ONGOING STUDIES WITHIN AE0D Enclosed for your information and use is a listing of current ongoing AE0D studies of operational events involving reactor and nonreactor activities.

Each study is identified by the responsible engineer, an assignment number, and a brief description. When completed, each study will normally be documented as either a technical review (TR) report, an engineering evalua-tion (EE) report, or as a case study (CS) report depending on the nature, seriousness, and implications of the event and any associated AE0D recomen-dations. The report closing out each completed study is identified in the-listing.

If additional information or discussion is desired on any specific study, please contact either the responsible engineer or supervisor (Stuart Rubin for reactor studies, Fred Hebdon for PTB studies, and Kathleen Black for nonreactor studies). Additionally, these individuals would appreciate knowing about related work or information within your offices that should be considered in either scoping or completing these studies.
