This report summarizes preliminary results on experiments, analyses and evaluations performed by Reactor Technology Section, Experimental Reactor Division during July through September, 1985. All results described in the report were released with internal memoranda of Reactor Technology Section, before detail analyses, evaluations, and/or discussions. Each result is classified into the following categories according to its content. (1)Results of analyses and evaluations for core characteristics of JOYO. (2)Calculation results of decay heat for core and subassembly of JOYO MK-II core. (3)Results of analyses and evaluations for large core design study. (4)Results of measurements and analyses for natural circulation test in JOYO MK-II core. (5)Results of reactor material dosimetry by foil and neutronic calculation in JOYO. (6)Measurement results of radiation shielding characteristics. (7)Results of analyses and evaluations for licensing (No.10). (8)Development of Fuel Failure Detection (FFD) technique. (9)Results of measurements and analyses for various plant characteristics of JOYO. (10)Production and/or arrangements of analysis codes and code manuals. (11)Miscellaneous results. After detail discussions, analyses and evaluations, the final report for each program will be published respectively.
