A quantitative expression of the capacity of a hot laboratory for post-irradiation examinations and experiments should serve most usefully in scheduling hot laboratory operation. The method adopted in the Hot Laboratory of the Japan Atomic Energy Research Institute is what has been termed the "Cave-day method". It has been in trial use for half a year since Feb. 1966. The method has proved to be highly useful for formulating and adjusting the operating schedule of the Hot Laboratory, once the standard times required for the various kinds of cave work have been determined. Another key to its successful application is a good understanding between the utilizers and the hot cave administration concerning the principles applied in determining the yearly or half-yearly amounts of cave-days allotted in advance to utilizers.
