Assessment on Accident and Mitigation of Spent Fuel Pool in a Typical PWR

Volume 11: Mitigation Strategies for Beyond Design Basis Events, 2022
In consideration of low power rate and large water inventory in spent fuel pool (SFP), the accident progression may be very slow and the fuel melt accident was considered to be very unlikely in SFP.

Spent Fuel Pool Risk Analysis for a CPR1000 Unit

Volume 13: Risk Assessments and Management, 2022
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 ...

Nuclear Safety of an RBMK Spent Fuel Pool

Atomic Energy, 2016
Aspects 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 Accidents in a Nordic BWR

Volume 3: Nuclear Safety and Security; Codes, Standards, Licensing and Regulatory Issues; Computational Fluid Dynamics and Coupled Codes, 2013
Loss-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 ...

Consolidation of spent fuel rods as an option to increase the capacity of spent fuel pool

1998
Using 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.

VVER-1000/V446 spent fuel pool risk assessment and support through portable mitigating equipment

, 2021
The Spent Fuel Pool (SFP) accident at the Fukushima Daiichi unit 4 demonstrated the need for identifying and analyzing possible accident sequences and subsequent application of severe accident mitigating systems in LWR (Light Water Reactor) SFPs. In this

Analysis of a Spent Nuclear Fuel Storage Pool

Safety Engineering and Risk Analysis, 1994
Abstract 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
