Metal working fluid (MWF) plays a significant role in metal machining operations to obtain the desired dimensional accuracy and better surface quality in the machined component. Legislations have set limits on the usage of mineral based MWFs because of their carcinogenic behavior and adverse effect on health and the environment. The saturated fatty acid of vegetable oil facilitates a better layer of lubricant between work tool interface compared with the mineral oil based MWFs. This paper describes the surface quality of 0.2 % C and AISI 304 steels while using formulated novel white coconut oil based MWF and mineral oil based MWF in flood cooling and dry machining. The machining parameters were selected according to the recommended specifications, and quality of the machined surface was measured. The novel white coconut oil based MWF has expressed better surface quality for almost all the set of machining parameters compared to other cooling configurations.

The safety of metal cask and concrete cask storage technology has been verified by CRIEPI through several research programs on demonstrative testing for the interim storage of spent fuel. The results have been reflected in the safety requirements for dry casks issued by NISA/METI (Nuclear and Industrial Safety Agency, Ministry of Economy, Trade and Industry) of the Japanese government. On top of that, spent fuel integrity has been studied by the Japan Nuclear Energy Safety Organization (JNES). This paper reviews these research programs. Future issues include the long-term integrity of cask components and high burn-up spent fuel.
