Abstract: An isolation valve particularly well suited for use in nuclear reactor hydraulic control systems is disclosed. The valve includes an electro-magnetic actuator which may be energized to open the valve thereby permitting the lift flow needed to move fission rate control devices with respect to a fuel assembly. The fission rate control devices are provided with elements comprised of magnetic material which, with the devices fully retracted from the fuel assembly, will be positioned within the magnetic field generated by the valve actuator whereby the devices will be magnetically held in the retracted position.

Abstract: A delay valve particularly well suited for use in nuclear reactor hydraulic control systems and a control method employing the valve are disclosed. The valve includes a bellows attached to a plug member and a high resistance flow path between a first pressure source and the interior of the bellows whereby a predetermined time is required for each filling of the bellows and the accompanying movement of the plug member in a first direction. Fission rate control devices are positioned in response to delay valve operation which is controlled by the application of pressure from second and third sources to the exterior of the bellows in the proper sequence.
