The DENESYS has been developed to support examination of decommissioning plan aiming to use management data and experiences obtained through decommissioning of nuclear facilities effectively. In the development of the DENESYS, it is important efficiently to collect, and to analyze management data obtained from actual decommissioning of nuclear facilities. Then, collecting items of management data needed to examine decommissioning plan were extracted. And en efficient collecting method of the extracted collecting items was examined based on the JPDR decommissioning project. As a result, collecting items are work management data, waste management data. These data would be collected by suing daily work management report, waste record, and secondary record data in each JAEA site. In this report outline of collecting items and collecting method for decommissioning of nuclear facilities were described. And manual for collecting management data was introduced.

JMTR has a plan to produce Mo, which is the parent nuclide of radiopharmaceutical 
Tc, by (n,) method. The cooperation experiments for Mo adsorption and Tc elution with the Poly-Zirconium Compound (PZC) and the Molybdate Zirconium Gel (Zr-gel) methods were carried out at Kazakhstan National Nuclear Energy Center (NNC) in October, 2009. The Mo adsorption capability was the same level as reference data, however the Tc elution capability with PZC was lower than reference data in this test. Therefore, re-experiments of Mo adsorption and Tc elution with both methods were carried out at NNC. As a result, the Mo adsorption and Tc elution capabilities were obtained as the same levels as reference data. Additionally, Tc solution was high purity by the elution method connected with alumina column.

Type 316 stainless steels (SSs) were used for tube material of the Oarai water loop No.2 (OWL-2) in the reactor. But data of highly irradiated Type 316 SSs has been insufficient since OWL-2 was installed. Therefore surveillance tests of type 316 SSs which were irradiated up to 3.4 
10
n/m
in fast neutron fluence (
1 MeV) were performed. But type 316 SSs were widely used in JMTR, then additional data of type 316 SSs irradiated higher was required. Therefore PIEs of type 316 SSs surveillance specimens which were irradiated up to 1.0 10
n/m in fast neutron fluence were performed and reported in this paper. Tendency of results has good agreement with results of 10
-10 n/m in fast neutron fluence. More than 37 % in total elongation was confirmed in all test conditions. It is confirmed that type 316 SS irradiated up to 1.0 10 n/m in fast neutron fluence has enough ductility as structure material.

J-PARC accelerator devices are controlled by the use of the software called EPICS. The unique name called an EPICS record is given to a control signal and data acquisition, Accelerator device control are achieved using the EPICS record. The requirement for the EPICS record name is 2 points; (1) no overlap of the EPICS record name, (2) the control contents can be easily imagined from the EPICS record name. To manage the EPICS record using relational database for the information management of the accelerator device in J-PARC, it is required to compose that a mechanical process can be performed easily. It was necessary to standardize the EPICS record name and the EPICS record structure to achieve these requirements. Therefore, we have formulated a guideline called "EPICS record naming conventions" to decide to an EPICS record name uniquely and standardization.
