权利要求

1. In a nuclear reactor pressure vessel defined by a concrete wall having stressing tendons to pre-stress the concrete, and bores accommodating heat-exchanger tube banks, each of said bores being closed by a closure member, the improvement comprising means provided upon each of said closure members and engaging some of said stressing tendons whereby each closure member is held in position.

2. A nuclear reactor pressure vessel comprising a concrete vessel wall, stressing tendons passing through said concrete wall thereby pre-stressing said concrete, pods provided in said wall and accommodating heat-exchanger tube banks, each pod extending to the outer surface of the wall, and a closure member closing each of said pods, each of said closure members being held in position by means of some of said stressing tendons.

3. A nuclear reactor pressure vessel according to claim 2, wherein the closure member is in the form of a closed tubular member having a flange through which pass the stressing tendons.

4. A nuclear reactor pressure vessel according to claim 2, wherein the closure member is in the form of a cylindrical member with one end closed and the other end having a flange which rests upon a seating at the outer end of the pod, stressing tendons passing through the vessel and disposed around the pod being arranged to pass through openings in the flange of the closure member and having tendon tensioning devices adapted to act against the flange to hold the closure member in position.

5. A nuclear reactor pressure vessel according to claim 3, wherein the tendons lie on concentric rings.
