JNC has developed a Remote Monitoring System (RMS) for unattended mode NDA in corporation with Los Alamos National Laboratory (LANL) under a JNC/DOE safeguards cooperation agreement. The purpose of this development is to improve the efficiency of safeguards activities for both the operator and the inspectors, and to improve transparency of nuclear material management. As a result of the field trials, technical problems of the RMS have been mostly resolved. Therefore, the JNC is evaluating how the RMS may contribute to the efficiency of safeguards activities by step-by-step implementation of RMS to PFPF in near future. Extending the RMS into not only storage areas, but also fuel fabrication process areas, has the possibility of reduction of actual visits to the facility. There is also the possibility of reduction of impact on facility operations. This paper describes the plans of JNC and LANL for applying RMS at PFPF.

A technique of measuring rapidly and correctly the concentration of Pu contained in the high radioactive liquid waste in a reprocessing plant has been developed. This method is based on spectrophotometry using Nd as an internal standard, and can be expected the application as measurement technology for the safeguards which has been utilizing the conventional method of isotope dilution mass spectrometry. This report describes the measurement principle and the result of the examination which used a real sample.

A rapid verification technique with conventional spectrophotometer has been developed to achieve on-site safeguards measurements in which neodymium as an internal standard was chosen to determine the plutonium concentration in high radioactive liquid waste.This method will provide the on-site analytical capabilities as it allows rapid and simple analyses at Tokai Reprocessing Plant.
