In order to reduce the influence on a plant schedule of the MONJU by the maintenance of dew point hygrometers, The JAEA examined a capacitance type dew point hygrometer as an alternative dew point hygrometer for a lithium-chloride type dew point hygrometer which had been used at the CV-LRT in the MONJU. As a result of comparing a capacitance type dew point hygrometer with a lithium-chloride type dew point hygrometer at the CV-LRT (Atmosphere: nitrogen, Testing time: 24 hours), there weren't significant difference between a capacitance type dew point hygrometer and a lithium-chloride type dew point hygrometer. As a result of comparing a capacitance dew point hygrometer with a high-mirror-surface type dew point hygrometer for long term verification (Atmosphere: air, Testing time: 24 months), the JAEA confirmed that a capacitance type dew point hygrometer satisfied the instrument specification (2.04C) required by the JEAC4203-2008.

A Consideration on direction of nuclear data as a database

Fukahori, Tokio

no journal, , 

Requirements for databases are verification, validation and completeness. In the case of nuclear data, the verification stands on accuracy with uncertainty coming from differential experimental data. The validation does on benchmark tests with integral experimental data. The completeness is also necessary for targets, incident energy, reaction channels, etc. In this presentation, the direction of nuclear data as a database is considered. The future direction of nuclear data is introduced philosophically as well as history of nuclear data development, perspective of nuclear data, and requests.
