Control component retainer
Creators
Description
A retainer to provide supplemental holddown force for a control component assembly latched into a fuel assembly of a nuclear reactor is described. Upon failure of latching mechanism the retainer precludes the ejection of the control component assembly from the fuel assembly by the upward coolant flow drag force. The spring loaded retainer is mounted at the top of the control component assembly and engages both the control component assembly and the core grid plate to form a structural blocking of the grid plate hole thereby precluding the ejection of the control component assembly therethrough
