The Net Pressure Driving Force Due To Boiling in Calandria Tubes
, 2000 Vapour formation due to boiling in calandria tubes provides the driving force for natural circulation in vacuum pans. The net pressure difference generated across a calandria tube is determined by the average density deficit in the tube relative to the ...

Development of Crystallographic Texture in CANDU Calandria Tubes
2002The Zircaloy-2 calandria tubes in a CANDU nuclear reactor separate the hot Zr-2.5Nb pressure tubes from the cool moderator. These tubes are about 6 m long, have an outside diameter of 132 mm, and a wall thickness of 1.4 mm. To date, their performance has been exemplary.

The thermal interaction of a buoyant plume from a calandria tube with an oblique jet
Nuclear Engineering and Design, 2016Abstract Severe reactor core damage may occur from fuel channel failure as a consequence of excessive heat emitted from calandria tubes (CTs) in a pressurised heavy water (D 2 O) reactor (CANDU). The heating of the CTs is caused by creep deformation of the pressure tubes (PTs), which may be ballooning or sagging depending on the internal pressure of ...

Pressure-tube and calandria-tube deformation following a single-channel blockage event in ACR-700
Nuclear Engineering and Design, 2007Abstract One postulated accident scenario for the Advanced CANDU Reactor (ACR-700™) is the complete coolant flow blockage of a single pressure-tube (PT). The flow is not monitored within each individual PT, thus during the early stages of this accident the reactor remains at full power and full pressure, resulting in rapid coolant boil-off and fuel ...

Abstract Sag of CT or liquid injection shutdown system tubes in pressurized heavy water reactor is known to occur due to irradiation creep and growth during plant operation. When the sag of CT is big enough, the CT tube possibly comes in contact with liquid injection shutdown system tube (LIN) crossing beneath the CT, which subsequently may prevent ...

COMPUTATIONAL PROCEDURE FOR EARTHQUAKE RESPONSE ANALYSIS OF HORIZONTAL TUBE ARRAY IN CALANDRIA
ISET Journal of Earthquake Technology, 1999A rigorous computational procedure is presented for dynamic response analysis of horizontal tube array in partially-filled calandria including hydrodynamic interaction effects. The procedure is general enough to consider transfer of energy between the fluid-coupled tubes, effects of moderator sloshing in terms of magnitude and the distribution of ...
