During the period 1 February through 31 March, 1977 the study has concentrated on the selection of availability goals for tokamak fusion reactors and the development of time line flow diagrams for replacement of the first wall and blanket modules of the three baseline reactor designs. Overall plant availabilities have been selected at 72% for a nominal goal and 62% for a threshold. For fusion unique equipment these availabilities became 85% and 79%, respectively. The timeline for replacement of the UWMAK III first wall and blanket is complete with a total continuous time requirement of 29 days for one reactor segment. This translates to an availability of 87% (undiluted for personnel utilization and other similar factors) for fusion unique equipment when using one possible maintenance plan. In addition, a detailed study plan has been developed and accepted by DMFE, ERDA and a survey of maintenance practices and problems was conducted in eight fission reactor related facilities.
