A thery was developed to design a high pressure vessel with combined structure of the metal and the composite to withstand the pressure of several tens of thousands psias to reduce the weight of the impulse motor which produces high level of thrust within several tens of seconds. The elastic-plastic stress analyses were carried out to prove the validity of the design theory. A combustion chamber of the impulse motor was designed by the design theory, fabricated, and tested by the hydraulic pressure and the static firings. The bursting pressures from the tests were compared to those predicted by the design theory and the stress analyses and found to be almost the same. It will be possible to design the high pressure vessel with combined structure of the metal and the composite very easily by the proposed design theory.

A pyroprocess is currently being developed by KAERI to cope with a highly accumulated spent nuclear fuel in Korea. The pyroprocess produces a certain amount of high-level radioactive waste (HLW), which is solidified by a ceramic binder. The produced ceramic waste will be confined in a secure disposal canister and then placed in a deep geologic formation so as not to contaminate human environment. In this paper, the development of a disposal canister was overviewed by discussing mainly its design premises, constitution, manufacturing methods, corrosion resistance in a deep geologic environment, radiation shielding, and structural stability. The disposal canister should be safe from thermal, chemical, mechanical, and biological invasions for a very long time so as not to release any kind of radionuclides.

Used metallic can should be recycled from the point of view of environmental preservation and resource recycling. Metallic can is one of EPR items, and classified into steel can and aluminum can according to the can body material. In Korea about eighty percent of metallic cans are made of steel. In this article, production of cans and current status on domestic recycling of used metallic cans in recent years(2008-2012) were surveyed. Recycled ratio by weight of used steel and aluminum cans was about 80.8% and 81.8%, respectively in 2012. Totally it reached 81.8%.

It is necessary that used metallic can should be recycled from the point of view of environmental preservation and resource recycling. Metallic can is classified into steel can and aluminum can according to the can body material. In Korea above eighty percent of cans are made from steel. In this article, production of cans and current status on the recycling of the used cans in recent years were surveyed. Recycled weight ratio of steel and aluminum can was about 75.6% and 74%, respectively in 2007. And totally it reached 75.3%.
