SUBJECT:
ONGOING JTUDIES WITHIH AE00 Enclosed for your infonnation and use is a listing of current ongoing AE00 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 docunented 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 inplications of the event and any associated AE00 recommen-dations. The report closing out each study is identifled in the listing.
If additional information or discussion is desired on any specific study, please contact either the responsible engineer or supervisor (Karl Seyfrit for reactor studies, Fred Hebdon for PTB studies, and Kathleen Black for nonreactor studies). Additionally, these individuals would appreciate
[
knowing about related work or infonnation within your offices that should
/
4 be considered in either scoping or completing these studies.
