PROCESSED SPENT FUEL STORAGE

LILW from conditioning and HLW from reprocessing impose different requirements on the interim storage. 

It is likely that processed spent fuel, i.e. either LILW or HLW, will be stored in extended interim dry storage in each country of the region until a deep geological repository is available. 

These materials are most likely to be stored in each individual country. Regional or extra-regional solutions are not foreseen as long as they constitute radioactive wastes for which storage of radioactive waste from third parties is forbidden by law in all countries participating in TC Regional Project RLA/4/0I8.

The licensing process consists of two steps construction and operating license that must be completed before fuel loading. Licensing covers radiological safety, environmental protection, and antitru,st considerations. Activities not defined as production or utilization of special nuclear material (SNM), use simple one-step. Materials Licenses, for the possession of radioactive materials. Examples are uranium mills, solution recovery plants, UO fabrication plants, interim spent fuel storage, and isotopic separation plants. 

The results obtained from the evaluation of rack 1 coupons indicate that some corrosion processes were taking place. There were differences in corrosion resistance between the different aluminium alloys. Corrosion of these alloys in the water at the KFKI spent fuel storage pool was probably more dependent on the materials than on the duration of exposure to the pool water. The duration of one to two years is probably insufficient to show major differences in high quality water.

Riel Processing, Spent-Fuel Transportation, Storage and Waste Disposal... 

For the aluminium based RRSF, currently in operational and interim wet storage, interim dry storage of the processed spent fuel is being considered. 

GT-MHR SPENT FUEL STORAGE DISPOSAL WITHOUT PROCESSING... 

Possibility of GT-MHR spent fuel storage during long tune without additional processing is discussed m this paper... 

Radioactive effluents and wastes were generated in a variety of process systems. These radioactive wastes included reactor primary coolant water, spent fuel storage basin cooling water, reactor periphery systems cooling water, reactor primary-coolant-loop decontamination and rinse solution, and miscellaneous drainage from reactor support facilities (WHC 1987a). 

N Reactor fuel elements were discharged to the spent fuel basin via a large tunnel-like canal located at the outlet face of the N Reactor. During this transfer process, a large quantity of reactor primary-cooling-circuit water, containing considerable amounts of suspended and soluble metals and metal oxides was added to the spent fuel storage basin. Excess basin water was routed to the 116-N-l and/or 116-N-3 cribs via the basin overflow weirs and a... 

It should be recognized that in some Members States the general public is involved in the decision making process on the acceptability of proposed interim spent fuel storage facilities. 

In addition to the general applicability of the iterative design process described above, there exist various technical, administrative and safety requirements which are also relevant to all designs of spent fuel storage facilities. These requirements are discussed below. 

A protective shell houses the reactor unit with auxiliary systems, spent fuel storage pool, and transport and process equipment. 

Although the energy supply in Korea has been ensured by nuclear power, the continuous increase of the nuclear power plants has caused a spent fuel storage problem. Therefore, a technical alternative to solve the spent fuel management is necessary to technically support the decision making process for spent fuel management. 

Perhaps there should be centralized areas for storage of spent fuel from present reactor types. These storage areas should be adjacent to reprocessing plants which would be built to process the spent fuel to provide the new fuel for the Fast Reactors going on line.
