The Waste Volume Reduction Facility (WVRF) was constructed for volume reduction and the chemical stabilization of the low level radioactive waste in the Nuclear Science Research Institute of JAEA. The metal melting system in the WVRF treats radioactive metal waste. From the experience of trial operations, the improvement has conducted on the casting process in the metal melting system. The performance of the improved casting process was verified through the trial operations from Oct. 2008. In this report, we describe the reduction of the processing time, of the utilities consumption, of the load of maintenance on the improved casting process.

In order to obtain the knowledge about cesium accumulations into the refractory in ash melting of decontamination waste, the immersion test was worked by immersing the refractory into melting slug including cesium, and cesium chemical forms in the refractory were analyzed.
