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.

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 ...

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

Development of INSPCT-S for Inspection of Spent Fuel Pool

Journal of ASTM International, 2012
Abstract 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, 2014
The 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.

Radiological Implications of Spent Fuel Pool Capacity Increase by Spent Fuel Consolidation

2000
Our 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.

Spent Fuel Cladding Performance Analysis Under Spent Fuel Pool Boiling-off Accident

2017
In 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 ...

THERMAL-HYDRAULIC MODELING OF RERACKED SPENT FUEL POOL

2000
The simple model of the spent fuel pool for computer code GOTHIC, which enables calculation of thermal-hydraulic parameters of the reracked spent fuel pool of NPP Krško, has been developed. This model encompasses all basic characteristics of spent fuel pool, which are necessary to simulate a global behavior of spent fuel pool cooling. Within this model,

Corrosion Surveillance in Spent Fuel Storage Pools

CORROSION 1997, 1997
Abstract Corrosion of aluminum-clad spent nuclear fuel being stored in the light-water filled basins at the Savannah River Site was first observed in mid-1991. A corrosion surveillance program was initiated at that time in the P, K, and L-Reactor basins and in the Receiving Basin for Offsite Fuels (RBOF).

Reracking Possibilities of the NPP Krško Spent Fuel Pool

1998
Using the SCALE-4 code package reracking possibilities of the NPP Krško spent fuel pool were analyzed. Two cases were considered: the first case assuming the 40 years lifetime of the plant, and the second case assuming the 50 years lifetime of the plant.
