Abstract

A restraint assembly for use in restraining lateral movement of a reactor core relative to a reactor vessel wherein a plurality of restraint assemblies are interposed between the reactor core and the reactor vessel in circumferentially spaced relation about the core. Each lateral restraint assembly includes a face plate urged against the outer periphery of the core by a plurality of compression springs which enable radial preloading of outer reflector blocks about the core and resist low-level lateral motion of the core. A fixed radial key member cooperates with each face plate in a manner enabling vertical movement of the face plate relative to the key member but restraining movement of the face plate transverse to the key member in a plane transverse to the center axis of the core. In this manner, the key members which have their axes transverse to or subtending acute angles with the direction of a high energy force tending to move the core laterally relative to the reactor vessel restrain such lateral movement.

Lateral restraint assembly for reactor core

Patent Gorholt, W; Luci, R K

In a nuclear reactor including a reactor vessel defining a shielded core cavity having a reactor core extending vertically along a longitudinal axis and being located internally of the cavity, the reactor core is described which has layers of reflector blocks defining an outer peripheral surface for the core spaced from the vessel and being supported in a manner permitting at least limited lateral movement relative to the vessel; the combination therewith comprising lateral restraint means including lateral restraint assemblies disposed in the circumferential spaced relation about the periphery of the reactor core between the core and reactor vessel.

Reactor core lateral restraint assembly. [HTGR]

Patent Brown, S J; Gorholt, W

A spring pack for supporting a sprung mass relative to an unsprung mass includes a relatively low-rate spring unit and a relatively high-rate spring unit interconnected with each other and arranged between the sprung and unsprung masses, the relatively low-rate spring unit tending to respond to initial limited movement between the sprung and unsprung masses, a mechanical stop limiting the spring response of the relatively low-rate spring unit with relative movement beyond that limit tending to be absorbed by the relatively high-rate spring unit. A plurality of the spring packs are employed in a lateral restraint assembly for laterally supportingmore »« less
Nuclear reactor support and seismic restraint with in-vessel core retention cooling features

Patent Edwards, Tyler A.; Edwards, Michael J.

A nuclear reactor including a lateral seismic restraint with a vertically oriented pin attached to the lower vessel head and a mating pin socket attached to the floor. Thermally insulating materials are disposed alongside the exterior surface of a lower portion of the reactor pressure vessel including at least the lower vessel head.

Modular assembly for supporting, straining, and directing flow to a core in a nuclear reactor

Patent Pennell, William E [Greensburg, PA]

A reactor core support arrangement for supporting, straining, and providing fluid flow to the core and periphery of a nuclear reactor during normal operation. A plurality of removable inlet modular units are contained within permanent liners in the lower supporting plate of the reactor vessel lower internals. During normal operation (1) each inlet modular unit directs main coolant flow to a plurality of core assemblies, the latter being removably supported in receptacles in the upper portion of the modular unit and (2) each inlet modular unit may direct bypass flow to a low pressure annular region of the reactor vessel.more »« less

Magnetic nuclear core restraint and control

Patent Cooper, Martin H [Monroeville, PA]

A lateral restraint and control system for a nuclear reactor core adaptable to provide an inherent decrease of core reactivity in response to abnormally high reactor coolant fluid temperatures. An electromagnet is associated with structure for radially compressing the core during normal reactor conditions. A portion of the structures forming a magnetic circuit are composed of ferromagnetic material having a curie temperature corresponding to a selected coolant fluid temperature. Upon a selected signal, or inherently upon a preselected rise in coolant temperature, the magnetic force is decreased a given amount sufficient to relieve the compression force so as to allowmore »« less
