Title: Passive heat removal from reactor safety vessel - includes splitting heat-entraining air flow in interspace into 2 streams, so that only smaller stream passes through filter, reducing filter area requirement
Inventor: EIBL JOSEF PROF DR
IPC: G21C15/26
Filed: 1991-08-17
Abstract: Passive heat removal from the concrete-housed safety vessel of a nuclear reactor involves initial heat transfer through the steel safety vessel by conduction and radiation and then upward transfer by means of air and natural convection in the interspace between the safety vessel and the concrete housing for filtration and release to atmos. through a housing opening. The novelty is that the heat-entraining air flow in the interspace is split into two streams, only the inner smaller stream directed at the safety vessel being passed through the filter, while outer larger stream is released without filtering. A nuclear reactor containment for carrying out the process is also claimed. ADVANTAGE - Satisfactory heat removal is achieved without the need for an excessively large filter surface area.

Patent DE-4215098-A1 (DE)
Inventor: BECKER KARL-HEINZ
IPC: F16H25/20
Filed: 1992-05-07
Abstract: It consists of a housing in which a push tube is movably mounted. Guided inside the push tube is a release tube which is displaceable relative to the push tube. The push tube is firmly connected to a spindle cage. The spindle cage is guided by a spindle via balls lying in between and is supported on the inner wall of the release tube. The release tube has recesses so that, moved with its recesses into the area of the balls, it receives these balls and thus interrupts the power flow between spindle cage and spindle. In this state, the spindle cage can easily be moved up and down on the spindle with the push tube and the release tube. <IMAGE>
