Abstract

This paper describes the design development and evaluation of a thermally comfortable pressure suit and associated equipment, using the vortex cooling effect for use during access penetrations into the United Kingdom-designed, advanced gas-cooled nuclear reactor system (AGR). Also discussed is the method of assessment of clothing materials. The system design of a heat balance equation using the Ranque Hilsch cooling effect produced by a vortex cooling tube, used in conjunction with a ventile clothing assembly, and the operation of a system to achieve adequate protection for persons working for extended periods in abnormal environments are demonstrated.
