Patent ES-464715-A1 (ES)
Title: Method and apparatus for load following with a single-cycle boiling moderator-coolant nuclear reactor
IPC: G21D3/14
Filed: 1977-12-02
Abstract: The invention is directed to a method and apparatus for providing a single-cycle boiling moderator-coolant nuclear reactor which accommodates changes in demand with a turbine generator on direct governor control. Current single-cycle boiling moderator-coolant nuclear reactors employ turbine generators that are slaved to the reactor. This arrangement is dictated because of inherent response limitations of the single-cycle boiling moderator-coolant nuclear reactor. The system of the present invention diverts steam from steam consuming normal auxiliary plant equipment to maintain reactor pressure when a rapid increase in turbine power demand is made such as during a daily load following or a frequency regulation change in demand. This allows the turbine generator to be placed on direct governor control. Rapid positive or negative demands accepted by the turbine cause a decrease or an increase in the pressure of the reactor. Reactor pressure is monitored by a pressure regulator which in the case of a rapid increase in demand throttles steam normally directed to feedwater heaters or steam reheaters and redirects the steam to the turbine. In the case of a rapid decrease in demand the pressure regulator by-passes a portion of the primary flow of steam to a condenser. Steam is redirected or by-passed until the reactor has time to respond to the change in demand.

Title: Solar energy system
IPC: F24J2/04
Filed: 1979-06-06
Abstract: A system for generating solar energy utilizes a plurality of solar radiation absorption bodies formed as spherical balls which interact with solar radiation focalization devices which constitute paraboloid mirrors in order to effect heating of the spherical balls by the solar radiation which is concentrated at an irradiation position defined by the paraboloid mirrors.
