Decay heat removal in the ITER outline design
Fusion Engineering and Design, 1996Abstract Decay heat densities are fairly small in ITER when compared to fission plants. The global decay heat in the water cooled shielding blanket design of ITER (fusion power 1.5 GW) is about 20 MW at shutdown and decreases to 1.5 MW after one day after which it stays fairly constant (1 MW after one month).

Reliability studies of decay heat removal system
2010 2nd International Conference on Reliability, Safety and Hazard - Risk-Based Technologies and Physics-of-Failure Methods (ICRESH), 2010Passive systems have been implemented in most of the advanced reactors in order to improve the availability of the plant. In this paper the methodology used for performing the passive system reliability analysis has been discussed. A case study on passive decay heat removal system of large sized PHWRs has also been discussed.

The Choose of Decay Heat Removal Systems of SFR
Volume 6A: Thermal-Hydraulics and Safety Analyses, 2018A sodium-cooled fast reactor is a significant candidate for future power reactor systems. Decay heat removal is an essential function of reactor safety systems The decay heat removal system should have the capacity to remove the decay heat with natural circulation in any accident.

Decay heat removal possibilities are one of the three fundamental issues for the safety of a nuclear reactor. The sodium-cooled fast reactors have some intrinsic advantages to ensure this function: high thermal inertia, good capabilities of natural convection with sodium, use of air as the cooling source thus minimizing the consequences of a loss of ...

This study considers the decay heat removal through passive systems (i.e., natural convection) in the pool-type experimental reactor MYRRHA (SCK•CEN). The low velocities associated with natural convection may cause a degradation of the thermal mixing in ...

Passive decay heat removal in advanced LWR concepts
Nuclear Engineering and Design, 1993Abstract This paper explores the possibilities of developing a passive LWR design concept which could ensure sufficient decay heat removal in the absence of emergency primary coolant supply without exceeding the safe temperature limit on cladding, and which could achieve large nominal operating power output in the range 600–1000 MWe.
