SUBJECT:
SITE VISIT TO WEST VALLEY TO OBTAIN HEAD END VENTILATION SYSTEM INFORMATION On October 25 and 26, 1978, we made the subject site visit. The attendees on the site visit are shown on the attached list.
The purpose of the site visit was to familiarize ORNL analysts with the plant head-end ventilation system and obtain additional infor-mation on the system details. This information is primarily being used in our ongoing analysis of the effects of a tornado on the plant.
We are currently considering various sizes of tornados in our analysis.
Some of the information provided by Nuclear Fuel Services cnnsisted of copies of engineering drawings of the head end ventilation system.
These drawings are to be used by the ORNL analysts and will be returned to the NRC upon completion of the task. At that time they will be inserted into the docket file.
Nuclear Fuel Services has agreed to obtain additional radiation level readings at various locations in the General Purpose and Process Mechanical Cells.
This data will provide a further bases for estimating contaimination levels in those cells.
This information was to be forwarded to A. T. Clark.
While at the site a detailed flow diagram of the head end ventilation system was composed by NRC and ORNL analysts.
This diagram will be used for constructing an up-to-date model for computer analysis using the TVENT code at ORNL.
