METHOD AND DEVICE FOR EMERGENCY EXTRACTING BUNDLE OF FUEL RODS FROM TILTER CASE Russian patent published in 2017 - IPC B66C1/32 

FIELD: physics.

SUBSTANCE: load handling device is mounted into the gap between the tilter case and the bundle of fuel rods for emergency extracting the bundle of fuel rods from the tilter case, the bundle of fuel rods is captured with a power grid, the load handling device is mounted with the bundle of fuel rods into the tilter of the second protecting camera chain of the separation section, the bushing is removed, the tilter lid is closed, the tilter is rotated by 180 degrees, the tilter lid is removed, the bushing is mounted on the housing of the load handling device, the load handling device is removed from the tilter. The bundle of fuel rods is left inside the case with the power grid at the top, and separating the spent fuel assemblies is continued according to the standard techniques. The load handling device is made of two parts: a cylindrical housing and a bushing, six rectangular grooves are formed at the bottom of the housing, in which six spring-loaded tabs are mounted on the axes, six holes are made at both ends of the housing for mounting the bushing, and the bushing is a cylinder with six threaded holes, in which captive screws are screwed, by which the bushing is fixed on the housing, the top of the bushing has a groove for gripping the vial caps of separating the spent fuel assemblies.

EFFECT: improving the work safety, lowering the radiation dose to the staff in the repair of the emergency tilter.
