Aging management is applied to dry storage systems used to store used nuclear fuel to ensure that material degradation does not affect the function and safety of these systems as they remain in service beyond the initial licensing period. Chloride-Induced Stress Corrosion Cracking (CISCC) is a potential degradation mechanism for welded stainless steel canisters that serve structural and...
At present, Ukraine has two spent fuel storage facilities under operation: wet spent fuel storage at Chernobyl NPP for RBMK-1000 fuel and dry spent fuel storage at Zaporizhzhya NPP for VVER-1000 fuel. Two more dry spent fuel storage facilities are under construction. The design of the ZNPP dry spent fuel storage facility was based on the VSC-24 interim spent fuel storage system used in the...
The evaluation of cladding integrity is a major issue to be demonstrated in Germany for extended interim storage periods up to 100 years and subsequent transportation considering operational and accidental conditions with respect to reactor operation, cask drying and dry interim storage. The chemical reaction between the zirconium fuel cladding and the cooling water in water-cooled reactors...
In order to use the concrete cask system for the storage of spent fuels in Japan, it’s necessary to establish method to manage aging effect, especially SCC (Stress Corrosion Cracking). Therefore, the methods are under development to mitigate SCC, to inspect crack, and to monitor confinement of a canister. For the mitigation of SCC, one of following factors should be kept in the certain...
The main function of the Interim Storage for Spent Nuclear Fuel (ISSF) in Serpong site is to store-underwater the Spent Nuclear Fuel (SNF) arising from the operation of the GA Siwabessy Multipurpose Reactor (GAS-MPR). Structure, system, and components (SSCs) of ISSF was built in 1997 and was designed by AEA Engineering, United Kingdom (UK - AEA). ISSF began to obtain operating licenses in 2008...
Spent fuel information are essential to make a national policy for spent fuel management, to evaluate the safety of transportation, storage facility and disposal facility. For that reason, The AMORES program (Automatic Multi-batch ORIGEN Runner for Evaluation of Spent fuel) was developed and used to evaluate inventory, radioactivity, and thermal power of transport cask or storage cask. This...
Indonesia has G.A. Siwabessy reactor (RSG-GAS) that is currently in operation. Indonesia also has Interim Storage for Spent Fuels (ISSF) that is store for Spent Fuels (SFs) of RSG-GAS 30 MWt. In the national policy on Radioactive Waste Management Strategy, SFs are categorized as High-Level Waste and are not recycled because Indonesia follows open nuclear fuel cycle. SF is a fuel element type...
This paper introduces three books recently published on transport and storage of radioactive materials. The transport and storage technologies have been established by accumulation of experiences and researches. Such works should be shared and used by readers and the future generations to advance the technology effectively.
The first book is “Safe and Secure Transport and Storage of...
The Pakistan nuclear power generation capability is progressing rapidly. Currently five Nuclear Power Plants are in operation and two Nuclear Power Plants are under construction. Pakistan is committed towards safe, secure and sustainable management of spent fuel generated from its Nuclear Power Plants operation. The spent fuel so far generated is stored at reactor spent fuel pools under water....
Due to the stringent requirements after the Fukushima accident and due to stricter requirements arising from the new design extension conditions (DEC) requirements which have been adopted into new Slovenian nuclear legislation, the Krško NPP decided to implement the safety upgrade project (SUP). SUP also envisages the safety upgrade of spent fuel storage. The NPP decided to construct a new...
