This paper describes all the activities that were executed by JNC related to JCO criticality accident on September 30,1999. During the JCO accident, the activities of radiation monitoring, environmental monitoring, criticality termination operation, computer simulation of criticality accident, whole body exposure measurements by WBC about 24-Na, back up of local government like consultation of residents near by were performed by JNC. After the accident Japanese government and Nuclear Safety Commission establishes the investigation committee of JCO accident. JNC has also back up this activity. For example, investigation of the causes, accident scenario, estimation of the doses of the workers and personnel for deserter, counter measure operation. This paper summarizes all the important activity executed by JNC in the meantime.

TRP's (Tokai Reprocessing Plant) coor dination on TRP safeguars improvement plan

; ; ; ; Sugiyama, Toshihide

Proceedings of INMM 39th Annual Meeting, 0 Pages, 1998/07

iaea full-scope safeguards has been carried out from spent fuel reciept to uranium and plutonium product shipments in trp, and so specified problems have occurred for implementation of iaea safegurds. recently iaea rose the new guideline that was strength of safegurds and proposed the safegurds improvement plans for trp in 1995, too. the main proposals are ; provision of more information including design information to iaea, installation of solution measurement and monitoring system for main tanks, implementation of safegurds for main process including waste, evaluations of errors and unmeasured inventory when nrta (near real time material accountancy) would be the conventional accountacy. trp has tackled these improvement items actively. in this paper, it is reported that contents of thes

Physical inventory taking at Tokai Reprocessing Plant (TRP)

; ; ; Sugiyama, Toshihide

Proceedings of 19th Annual ESARDA Symposium on Safeguards and Nuclear Material Management, 0 Pages, 1997/05

TRP has performed PIT forty threetimes since 1977. There are three MBAs, which are spent fuel storagearea, process area and product storage area. Physical inventory is accounted by measuring of nuclear materials mostly in tank after clean-out of the process area. Inventory difference is calculated as an evalution of PIT. $$sigma$$ which is determined as an expected value of measurement uncertainties.

17TH ANNUAL SYMPOSIUM ON SAFEGUARDS AND NUCLEAR MATERIAL MANAGEMENT, 0 Pages, 1995/05

Nuclear material accounting control in the Tokai Reprocessing Plant is conducted by dividing into three material balance areas. Accounted data are input in the Material Accounting Control System(MACS). Physical Inventory Taking(PIT) has been conducted forty one times, and the material accounting control has been conducted properly by the evaluation of Material Unaccounted For(MUF) that was calculated

Material Accounting of Tokai Reprocessing Plant,Japan,is conductedby division into three material balance areas. Nuclear material data from the material accounting are input in the Material Accounting Control Computer System. 41 Physical Inventory Takings have been conducted, and MUF for each PIT has been calculated by the determination of the physical inventory. The MUF has been evaluated by calcula

This paper is compiled as a record of oral presentation by O.YAMAMURA at RECOD' 91 in April 15. 1991 in Sendai Japan with more than 600 attendance. It contains a proceeding, a manuscript of oral presentation and a manuscript of viewgraphs. The abstract of presentation is as belows. Since the start of construction of the Tokai Reprocessing Plant (TRP) in 1971, large efforts were taken by the Power Reactor and Nuclear Fuel Development Corporation (PNC) and various organizations to root the LWR fuel reprocessing technology in Japan. These efforts produced many achievements around the TRP, and now the future plan for the TRP is being studied.
