Spent Fuel Behavior in Water Pools
CORROSION 1981, 1981abstract This paper deals with the major question, "How long can the integrity of water-cooled reactor spent fuel cladding be maintained while the fuel is stored in water?" Evidence to date (1980) from the United States and other countries on spent fuel with Zircaloy and stainless steel cladding is described.

Nuclear Safety of an RBMK Spent Fuel Pool
Atomic Energy, 2016Aspects of the nuclear safety of the spent fuel pools of RMBK reactors under normal conditions and design basis and beyond design basis accidents are studied using a three-dimensional model verified by comparing with Monte Carlo calculations. It is shown that the storage of spent fuel assemblies in pencil-shaped cases secures nuclear safety in the ...

Spent Fuel Pool Risk Analysis for a CPR1000 Unit
Volume 13: Risk Assessments and Management, 2022Abstract After the Fukushima nuclear accident, the safety level of the spent fuel pool has gradually attracted increasing attention. This paper develops a probabilistic safety assessment (PSA) model for the spent fuel pool of a CPR1000 unit, and quantitatively evaluates the frequency of fuel damage.

Consolidation of spent fuel rods as an option to increase the capacity of spent fuel pool
1998Using the SCALE-4 code package we have analyzed consolidation possibilities of the NPP Krško spent fuel pool. We considered an approach to capacity increase of the NPP Krško spent fuel pool in which additional racks with consolidated fuel have to be designed and installed in the free space of the spent fuel pool.

Spent Fuel Pool Accidents in a Nordic BWR
Volume 3: Nuclear Safety and Security; Codes, Standards, Licensing and Regulatory Issues; Computational Fluid Dynamics and Coupled Codes, 2013Loss-of-pool-cooling accidents at the spent fuel pools in the reactor hall of a Nordic BWR have been studied using the MELCOR 1.8.6 code. Studies were made with several different calculation nodalizations. Other investigated variables were the total decay heat power of fuel assemblies in the pool, the initiator of the accident (loss of pool cooling or ...

Development of INSPCT-S for Inspection of Spent Fuel Pool
Journal of ASTM International, 2012Abstract In this paper, we discuss an accurate and fast software tool (INSPCT-S, Inspection of Nuclear Spent fuel-Pool Calculation Tool, version Spreadsheet) developed for calculation of the response of fission chambers placed in a spent fuel pool, such as Atucha-I.

Spent Fuel Pool Under Severe Accident Conditions
Volume 3: Next Generation Reactors and Advanced Reactors; Nuclear Safety and Security, 2014The possibility of a spent fuel severe accident has received increasing attention in the last decade, and in particular following the Fukushima accident. Several large scale experiments and also separate effect tests have been conducted to obtain a data base for model development and code validation.

Spent Fuel Cladding Performance Analysis Under Spent Fuel Pool Boiling-off Accident
2017In Fukushima Accident, spent fuel pool cooling system stopped working and water supply methods from outside was used, it seems that the possibility of cladding failure under spent pool boiling-off accident exists if no water supply lasts long. This report analyzes the spent fuel cladding performance under boiling-off accident, and the main parameter ...

Radiological Implications of Spent Fuel Pool Capacity Increase by Spent Fuel Consolidation
2000Our recent analysis showed that from the criticality standpoint it is possible to increase capacity of the NPP Krško spent fuel pool by spent fuel consolidation to accommodate spent fuel assemblies for plant lifetime. The spent fuel consolidation will also impact the radiation dose rates in the vicinity of the NPP Krško spent fuel pool.

Analysis of a Spent Nuclear Fuel Storage Pool
Safety Engineering and Risk Analysis, 1994Abstract A probabilistic analysis of a spent nuclear fuel storage pool was performed to identify any significant vulnerabilities. The pool structure is reinforced concrete set in bedrock. The pool is used to store 683 fuel assemblies that were discharged from a power reactor as recently as 1978. The analysis included
