Abstract

A boiling water reactor assembly includes a bayonet plate closure between a control rod guide tube and a drive housing pipe. The bayonet plate closure has a bayonet plate constructed in two parts including a central bayonet ring mounted rotatably about its longitudinal axis and an outer ring completely surrounding the bayonet ring. The outer ring is mounted on the periphery of the bayonet ring and reaches inwards under the bayonet ring periphery. The ring is furthermore permanently supported in the axial direction on the drive housing pipe by spring pressure acting on the control rod guide tube, in order to produce a frictional connection. The spring pressure can be released unhindered from the reactor side by tools.

First claim

The invention claimed is:

1. A boiling water reactor assembly, comprising:
a control rod guide tube having a base flange;
a drive housing pipe having a longitudinal axis defining an axial direction; and
a bayonet plate closure coaxially connecting said drive housing pipe to said control rod guide tube, said bayonet plate closure having a two-part bayonet plate including:
a) a central bayonet ring mounted rotatably about said longitudinal axis and having bayonet grooves, an u…
