Title

28 Element Pickering Production in P.T. 

Description

A closeup of the classical Pickering 28 element end plate with the bundle inside a Zr-Nb 2.5% pressure tube. Note the thickness of the pressure tube. The hoop stress on pressure vessels is directly proportional to diameter; hence the small diameter pressure tube walls can be much thinner than the thick walls required for a PWR pressure vessel. Thin Zr walls do not absorb many neutrons; hence the moderator can be placed outside the fuel area in a low pressure calandria. This is the essence of pressure tube reactor design vs. pressure vessel reactor design.
