The Impact

Computational study of the moderator flow in calandria vessel of a heavy water reactor is carried out for three different inlet nozzle configurations. For the computations, PHOENICS CFD code is used. The flow and temperature distribution for all the configurations are determined. The impact of moderator inlet jets on adjacent calandria tubes is studied. Based on these studies, it is found that the inlet nozzles can be designed in such a way that it can keep the impact velocity on calandria tubes within limit while keeping maximum moderator temperature well below its boiling limit.

This paper describes experience with glandless pumps on the S.G.H.W.R., both wet and dry stator types being included. The performance of the pumps is discussed and details given of the problems which arose in operations. Experience suggests that deposition in the pumps of radioactive corrosion products will not be a significant problem. The paper is in four parts: the functions, characteristics, and instrumentation of the pumps are outlined, followed by a description of some of the key results from commissioning tests.
