CLIRA DECAY HEAT REMOVAL TEST. [PDF]
, 1972 This report describes the design and fabrication of an electrically heated test section that was used to simulate the heat transport associated with the handling, after irradiation and discharge from the reactor vessel, of a fueled Fast Flux Test Facility (FFTF) closed loop test assembly while in the air-cooled ex-vessel handling machine.

Dynamic Hybrid Reliability Studies of a Decay Heat Removal System [PDF]
International Journal of Reliability, Quality and Safety Engineering, 2015 Some critical safety systems exhibit the characteristics of hybrid stochastic class whose performance depends on the dynamic interactions of deterministic variables of physical phenomena and probabilistic variables of system failures. However, conventional probabilistic safety assessment (PSA) method involves static event and linked fault tree analysis
