These articles have been peer-reviewed and accepted for publication in IJNSS, but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

  • Passive containment cooling system with hydrogen recombiner for prolonged station blackout   Order a copy of this article
    by Shripad T. Revankar 
    Abstract: An accident scenario beyond the design basis, where station blackout could lead to a severe accident with hydrogen release, has become important after the accident at Fukushima Daiichi nuclear plant. In this paper, a passive containment cooling system (PCCS) combined with a hydrogen mitigation system is suggested that will passively remove containment heat load as well as mitigate hydrogen from the containment atmosphere during a prolonged station blackout. It is proposed to make use of atmospheric air as the ultimate heat sink to reject the PCCS heat, which in turn will transfer heat from the containment. In the proposed design, a finned vertical tube type PCCS system submersed in pool water is considered, with the supply of pool water lasting three days following which airflow cools the PCCS tubes over the long term. The PCCS inlet flow path will have a catalytic recombiner that is effective during the first few days should there be any hydrogen generation and accumulation in the containment.

  • Physical protection systems of nuclear facilities: a proposed nuclear power plant general layout and regulatory requirements   Order a copy of this article
    by Olivea Elhefnawy, Mahmoud Barakat 
    Abstract: At present, great efforts in Egypt are directed towards elaborate physical protection regulations to protect nuclear and radiological facilities from any adversary actions, especially after signing the agreement between Egypt and Russia for the establishment of the first Egyptian nuclear power plant in Dabaa. The upcoming regulations will include a physical protection regulation of nuclear facilities and nuclear materials. Thus, the present work is concerned with a proposal of physical protection regulation of nuclear facilities. This proposal discussed the role of the licensee in defining threat assessment and design basis threat, followed by classifying different areas in the general layout of the nuclear facility or nuclear power plant. Also, the requirements of an efficient physical protection system were discussed based on the four basic elements, e.g. entry control, intrusion detection, delay of intruder, and response force. This suggested regulation takes into consideration the International Atomic Energy Agency recommendations and many other countries' regulations.
    Keywords: physical protection systems; nuclear facilities; nuclear power plant; general layout; threat assessment; design basis threat; regulatory requirements; entry control; intrusion detection; delay of intruder; response force.
