German physical protection concept for the storage of spent fuel elements in transport and storage casks
In this paper, the German physical protection concept for the storage of spent fuel elements in transport and storage casks is outlined. The presentation comprises the legal basis, relevant ordinances and regulatory framework, as well as important definitions such as disruptive acts or other interference by third parties. The essential elements of a physical protection concept for an interim ...

Experimental investigation of the late phase of spent fuel pool accidents
Experimental programmes have been carried out in order to investigate the behaviour of nuclear fuel components in high-temperature air atmosphere, which characterises the main conditions of the late phase of spent fuel pool accidents. The tests provided new data on the oxidation of zirconium cladding in different atmospheres, on the oxidation and release of ruthenium from fuel pellets and on the ...

Safety analysis of a VVER-440 spent fuel storage pool
Numerical analysis has been carried out for the spent fuel pools of the Paks Nuclear Power Plant (NPP), where the fuel assemblies are stored for several years after discharge from the reactor. The performed calculations covered both severe and design basis accidents. The results indicated that the spent fuel pool accidents may have severe consequences. For this reason new procedures have been ...

Environmental impact resulting from a fire at a spent nuclear fuel storage facility
Nuclear power reactors have created a significant quantity of used or spent nuclear fuel elements that contain some remaining nuclear fuel and by products of the fission process that are highly radioactive. Lack of a secure central repository or other permanent disposal process for spent nuclear fuel elements has resulted in long term storage of these elements in spent fuel pools at operating ...

A demonstration of the comparative radiological safety of commercial nuclear power generation in the USA
The most emotionally gripping topic of the debate over expansion of commercial nuclear power in the USA centres on the threat of radiological harm to the public from a commercial nuclear power plant accident. The perseverance of the radiation fear issue is reviewed herein, followed by summarisation of the expanded knowledge of reactor safety over the last 30 years. Analyses of maximum population ...

General leakage in fuel storage
Summary Owners and operators of fuel storage facilities are subject to regulations and codes of practice aimed at preventing leaks of fuel into the environment and ensuring prompt and effective clean-up in the event of a leak. Environmental contamination can come from spills, overfill of storage tanks and corrosion or deterioration of storage tanks - both above and below ground. Reactive action ...

Behaviour investigation of hematite nanorods synthesised by hydrothermal method use in hydrogen fuel storage
For the first time, hematite nanorods were successfully synthesised using iron nitrate precursors in the presence of cation SO4−2. This is also the first time that an investigation into hematite nanorods behaviour for hydrogen fuel storage has been carried out. Microspheres constructed with α-FeOOH nanorods were synthesised via a novel hydrothermal method using a mixture of Fe(NO3)3 · 4H2O and ...

Refined augmented Lagrange Hopfield network–based Lagrange relaxation for hydrothermal scheduling
This paper proposes a refined augmented Lagrange Hopfield network–based Lagrange relaxation (ALHN–LR) for solving short term hydrothermal scheduling (HTS) problem with pumped–storage hydro units. ALHN–LR consists of improved Lagrange relaxation (ILR) and augmented Lagrange Hopfield network (ALHN). For solving the HTS problem, the proposed method applies enhanced ILR for finding thermal unit ...

Value of nuclear power in the global energy system
With a global energy model which finds the minimum cost energy system over the time range of 1995-2055, the value of nuclear power is analysed. The model incorporates detailed descriptions of energy conversion technologies. For nuclear technologies, light water reactors and fast breeder reactors are taken into account with fuel cycle options. Major findings are: 1) the maximum introduction of ...

Case Study - Helmsley Open Air Pool
Helmsley Open Air Pool is operated by a registered charity – the Feversham Memorial Trust – and opens from June to September each summer. The 1930s pool is 25m in length and 10m wide. The existing heating system comprised an oil boiler working in tandem with an electric heat exchanger. During the 2007 season the oil boiler broke down and was in need of replacement. To keep the pool ...

Solutions for scientific problems related with temperature SNF storage regime
The dry long-term storage facility (SFSF-2) is a chamber-type structure formed by cast-in-place steel-concrete walls, top and bottom floorings separated with lateral steel-concrete partitions to several chambers. The main task in the creation of the storage facility is to provide an efficient natural air circulation circuit. A broad scope of experimental and computation researches has been ...

Prospects for nuclear energy in the 21st century: The East-Asian perspective
Although closely resembling each other geographically and socio-politically, Japan and Korea differ sharply in both technological and political terms with regard to the development of nuclear power. This paper aims to illustrate Japan and Korea's commonalities and differences and thereby to highlight the major short-term challenges facing them, such as the selection of radioactive waste storage ...

Gaseous release in LiNH2–MgH2 systems
Hydrogen is considered a safe and clean alternative to fossil fuels. Hydrogen storage is currently obtained by compressing the gas at high pressure. Researchers are currently attempting to tackle safety and energy density issues by locking hydrogen into solids, packing large quantities into small volumes. However, most of the known solids (i.e. intermetallics) show very low gravimetric density, ...

Scenarios for the role of hydrogen in a future energy system based on renewable energy
An all-renewable energy system for a group of North European countries is investigated by temporal simulation of the demand-supply matching for various system configurations. The role of hydrogen technologies for energy storage and fuel cell applications is studied and applied to both stationary and transportation sectors. It is shown that there is scope for considerable amounts of energy trade ...
