Report of the research results with University of Tokyo, Nuclear Engineering Research Laboratory's Facilities in fiscal 1987

The report of the results of research carried out by the common utilization of the reactor 'Yayoi' and an electron accelerator in the Nuclear Engineering Research Laboratory in fiscal year 1987 is ready. In fiscal year 1987, the research themes using the reactor Yayoi or related to it were 14, and those using the linear accelerator reached 17, thus the common utilization attracted the strong interest of users. The Yayoi has been operated satisfactorily without trouble. The budget for remodeling the control rod driving mechanism which has been a pending was approved, and it is expected to carry out the general overhaul at the end of this fiscal year, placing emphasis on the improvement of the maintainability. On the other hand, as for the linear accelerator, the budget for repair and remodeling was approved from fiscal year 1987, and it is expected that its function is further heightened as a twin linac. However accompanying the repair, sufficient machine time was not allotted to some groups. In this report, the results of the research carried out by the common utilization of the Yayoi and a linac and the reports of 12 Yayoi research meetings in fiscal year 1987 are collected. (K.I.)
