The Design, Manufacture and Testing of a New Generation of ISO Freight Container for Certification as an IP-2 Package in Compliance with the IAEA Regulations for the Safe Transport of Radioactive Material – 1985 Edition (as Amended 1990)

Abstract: Solid low level radioactive waste (LLW) which arises at nuclear power stations and other nuclear facilities in the UK, is routinely transported to British Nuclear Fuels site at Drigg in Cumbria for disposal. A requirement was identified for the use of an ISO freight container of the full-height design, to transport drummed LLW to the site of a supercompaction facility prior to disposal at Drigg. This was initially accomplished using refurbished containers incorporating a number of enhanced features. It was recognised that the use of a refurbished container was only an interim measure and as a result of significant changes in the acceptance criteria for disposal, the increased use of high force compaction techniques and the proposed amendments to the IAEA Transport Regulations, Nuclear Electric embarked upon the development of a new generation of ISO freight container. The new design of container, Design No. 2044, incorporates a readily decontaminable stainless steel interior, a comprehensive load ...

Impact of an Exploding LPG Rail Tank Car Onto a Castor Spent Fuel Cask

Abstract: On 27 April 1999 a fire test was performed with a 45 m3 rail tank car partially filled with 10 m3 pressurised liquid propane. A CASTOR THTR/AVR spent fuel transport cask was positioned beside the propane tank as to suffer maximum damage from any explosion. About 17 min after fire ignition the propane tank ruptured. This resulted in a BLEVE with an expanding fireball, heat radiation, explosion overpressure, and tank fragments projected towards the cask. This imposed severe mechanical and thermal impacts directly onto the CASTOR cask, moving it 7 m from its original position. This involved rotation of the cask with the lid end travelling 10 m before it crashed into the ground. Post-test investigaiions of the CASTOR cask demonstrated that no loss of leaktightness or containment and shielding integrity occurred.

The Penetration of Aerosols Through Fine Capillaries

Abstract: A practical procedure has not been developed and accepted internationally to quantify the leakage of aerosols in tests of radioactivity transport flasks. Hence it is necessary to understand how aerosols penetrate model pathways that have leakage rates close to the limits set by standards of flask integrity. A novel procedure has been developed to study the penetration of particles ranging from 0.5 to 15 μm volume equivalent diameter through capillaries varying from 20 to 80 μm bore and from 10 to 50 mm in length. The penetration of these particles was smaller than expected from a comparison of particle diameter with capillary bore, and showed a linear correlation with flow Reynolds number when both variables were plotted on a logarithmic scale. The lack of particle size dependent penetration was explained in terms of the capillary operating as an aerosol sampler in calm conditions.
