Publication number: 20240125361Abstract: An electro-magnetic coil assembly mounted to a clutch assembly, the electromagnetic coil assembly including a coil mounted within an annular coil housing and a flexible armature plate. The coil assembly adapted to generate an electromagnetic field between the coil and the armature plate for attracting the armature plate to the coil assembly. The flexible armature plate includes an annular plate with an outer edge and an inner edge, the outer edge defining an outer periphery, the inner edge defining an inner periphery. Tangs spaced about the inner periphery extending radially inward from the inner edge. Inner notches spaced about the inner periphery of the annular plate and extending radially outward to a point at least halfway in the radial direction between the inner edge and the outer edge. Outer notches spaced about the outer periphery between and extending radially inward.Type: ApplicationFiled: September 25, 2020Publication date: April 18, 2024Applicant: The Hilliard CorporationInventors: William J. COON, James E. PALMER, David C. OCHAB

Patent number: 11742100Abstract: A depressurisation valve for a cooling system including a main chamber having a main valve, a pilot line having a secondary valve and a blowdown line; the main valve being located to seal a path of the coolant system of the nuclear reactor. The main chamber is connected to the cooling circuit via the pilot line allowing coolant to enter the main chamber, and the blowdown line allows coolant to escape from the main chamber, the pilot line having a lower fluid resistance than the blowdown line. The pressure of coolant in the main chamber maintains the main valve in a closed position, and under elevated temperature and/or pressure conditions fluid is prevented from entering the main chamber via a closure of the secondary valve on the pilot line and reduce the pressure from the valve, moving it to its open position.Type: GrantFiled: June 28, 2022Date of Patent: August 29, 2023Assignee: ROLLS-ROYCE SMR LIMITEDInventors: Brenton D Shearer, James C Palmer, Benjamin J Ireland

Publication number: 20190164654Abstract: A nuclear power plant, having a reactor pressure vessel; a steam generator arranged to generate steam utilising thermal energy generated within the reactor pressure vessel; and a fluid circuit for transferring thermal energy from the reactor pressure vessel to the steam generator. The plant also has a coolant reservoir for storing coolant for supply to the steam generator under gravity in emergency conditions. The steam generator has a steam drying zone comprising one or more steam separators configured to dry steam; and the steam generator and coolant reservoir are configured such that when coolant is supplied from the coolant reservoir to the steam generator in emergency conditions the coolant stays below a threshold level defined by the steam drying zone.Type: ApplicationFiled: November 8, 2018Publication date: May 30, 2019Applicant: ROLLS-ROYCE plcInventor: James C.
