4O1l44e MEETING ON RADIOLOGICAL OPERATIONS ENEWETAK CLEANUP 6 January 1978 - Department of Energy, Germantown, MD 1. Purpose of Meeting. The Enewetak Cleanup project is a joint DoD-DoE effort which requires the fullest cooperation between agencies. At this time, the cleanup operation at Enewetak Atoll has reached the point where data and specific guidance are required so that critical on-site, day-to-day operational decisions can be made to assure that the finite resources available are used in the most effective and efficient manner and to insure that the cleanup effort results in the availability of land for its highest potential usage by the Enewetak people. Specifically, the following questions were in need of resolution: a. Should cleanup guidelines be based on transuranic elements instead of certain isotopes of Pu, as recommended by the AEC Task Group? b. What priority will be assigned in allocating resources to specific islands of the atoll? c. What constitutes the certification of completion of the work effort and the final record of the radiological status of the islands? 2. Summary of Principal Subjects. All transuranics will be included in determining contamination levels and soil volumes qualifying for removal. Completion of surveys and data analysis required to characterize the location and activity levels on each island is currently limiting the cleanup effort. A master work plan to show work effort and allocation of resources is required. Such a plan will be based on survey data, established island utilization as specified in the EIS, and cleanup guidelines recommended by the AEC Task Group Report as modified by FC DNA OPLAN 600-77. A dose assessment is required to establish an intermediate activity level for field use in cleanup of islands to be used for agricultural purposes. The cleanup work now planned for Runit will be deferred until a complete scope of work for the atoil can be defined and the available resources can be evaluated and allocated. The format for certification will generally include the radiological status of each island and an on-site judgment that within applicable radiation standards, the cleanup permits use of the island for its intended purpose and has been accomplished in accordance with the established guidelines. 3. Persons Present. See attached list. 4. Principal Topics of Discussion. 239.246 Transuranic Elements. The original cleanup guidance stated that 2 Pu were the only transuranic isotopes of concern which required removal. The principal consideration in making this judgment was the dose to the lung Foifile = 3.573 31 Jan 78 a Ai Y SOLE 136 (G29 — Avg 1G 7S
