摘要： A method for operating a controller having a number of timers to thereby control a plurality of events greater than the number of timers, includes, between clock ticks, receiving one or more signals from sensors, switches, executing programs, or a combination therefore that initiate one or more timed events. After a clock tick immediately following the receiving of the one or more signals, the method further includes updating entries in an event control block in accordance with the received signal or signals. The entries include a time remaining for pending events, a time past due for active events, and a priority of each event. The method further includes determining whether any pending event or events have timed out, activating any timed out events, and sending a signal notifying an executing program of the activated event having the highest priority.

摘要： A method and system is provided for a nuclear reactor safety related application. The method includes executing two forms of a same application-specific logic, one of the two forms implemented as hardware logic, and the other of the two forms implemented as software instructions for execution by microprocessor-based controlling software. Each form of the application-specific logic is executed with a same set of inputs. The method compares a result produced from the execution of the hardware-implemented form to a result produced from the execution of the software-implemented form. When the compared results concur, the controlling software performs actions associated with the concurring results by executing microprocessor-based software. When the compared results fail to concur, the controlling software reports the failure of the compared results to concur to an operator by executing microprocessor-based software, and thereafter places the microprocessor-based software system into an inoperative (INOP) mode.

摘要： A nuclear reactor plant is provided in which the reactor coolant system contains a dissolved solution of enriched boric acid. The boron-10 to boron-11 atomic isotope ratio of the enriched boric acid solution is greater than 30:70 at the start of the reactor core cycle. The nuclear reactor plant design provides for minimal mixing between the reactor coolant solution containing the enriched boric acid solution and the natural boric acid solution used during refueling operations.

摘要： Disclosed is a nuclear power plant comprising a high-temperature pebble bed reactor contained in a cylindrical steel pressure vessel in which an upper part of the cylindrical steel pressure vessel, which contains a heat utilization system, is retracted and equipped with a cover upon which circulating blowers are placed. The heat utilization system comprises, in a known manner, a single steam generator. The steam generator comprises at least two sub-systems independent of one another, with their own distributors and collectors, and with their own inlet and outlet lines. A first shut-down arrangement comprises a plurality of absorber rods insertable into bores of the side reflector from above and comprises rod drives arranged outside the steel pressure vessel in the area of its retracted upper part. A second shut-down arrangement comprises small absorber spheres for introducing into the core of the reactor, and several storage containers and annular conduits for said spheres. The storage containers are also arranged outside the steel pressure vessel in the area of its retracted upper part. Annular conduits for the introduction of the small absorber sphere are, however, disposed inside the steel pressure vessel and connected with channels provided in projections of the side reflector protruding into the core.

摘要： In an illustrative embodiment of the invention, approximately 0.1 percent by weight of sodium silicate is added to an aqueous radioiodine absorbing and decay heat removing spray mixture for discharge within a nuclear reactor containment building. The radioactive decontamination fluid preferably includes 1 percent by weight of sodium thiosulfate, 1.22 percent by weight of boric acid and 0.528 percent by weight of sodium hydroxide in a water solution. The added sodium silicate allows less expensive aluminum components to be used within the containment building because it inhibits a corrosive chemical reaction between the aluminum and the sodium hydroxide. Without the inhibitor, the aluminum-hydroxide reaction would lead to a potentially explosive mixture of hydrogen and oxygen within the containment building.
