A heat absorbing radiator and a gas turbine engine or a reciprocating piston engine are used to recapture and reconvert wasted heat energies into electric power and finally into hydrogen-deuterium fuel by having the engine's tailpipes submerged in cold compressed air inside the heat absorbing radiator pipes in reverse air flow to further drive the same engine. In order to capture fusion heat energy a hydrogen bomb is detonated in deep ocean to catch the flames by the water and the hot water energizes compressed air inside heat absorbing radiator pipes. In order to produce fusion energy an electric arc is passed thru / across liquid or gaseous deuterium by an electro-plasma torch and by a sparkplug in an internal combustion engine, or by detonating a dynamite inside liquid deuterium. Diamond is produced by placing carbon inside a hydrogen bomb which is then detonated in deepwater. Deuterium fusion flame is used first in smelting glass into large structural sizes before running an engine.

The invention relates to a passive containment shell condensed water injection system. The system comprises a first water collecting device; a first condensed water injection pipeline, which is connected to the first water collecting device and a pressure container direct injection pipeline; and a first valve mechanism, which is arranged on the first condensed water injection pipeline and is capable of starting the condensed water injection and controlling the condensed water injection flow after receiving a severe accident signal. The first water collecting device comprises a first water collecting groove, which is arranged along the circumferential direction of the internal wall of a containment shell. The first water collecting groove is arranged above the reactor core, and the standard distance between the first water collecting groove and the reactor core is 40% to 75% of the total height of the containment shell. When a severe accident happens, the system can utilize the pressure due to the height difference between the water collecting groove and the reactor core to completely inject the condensed water into the reactor core to ensure the safety of the reactor. Moreover, the system also can collect the condensed water from the internal wall of the containment shell and directly injects the collected condensed water into the reactor core to cool the melts in the reactor core. The system has the advantages of simple structure, high reliability, and suitability for various kinds of nuclear power stations.

The invention relates to a casting method of a cast steel cooling plate, which adopts a cast steel material to cast a cooling plate base body and a cooling water pipe. The casting method comprises the following steps: adding a slagging agent and a silicon iron alloy block in molten steel for casting steel; putting the cooling water pipe into a casting model, sheathing a pipe sleeve on the coolingwater pipe and leading a liquid cold medium and a composite solid cooling medium to pass through the cooling water pipe; using molten steel for casting steel to cast the cooling plate base body, and casting the middle part of the cooling water pipe into the cooling plate base body; leading the casting model to be horizontal in the modeling process, leading a feeder head to be modeled lopsidedly toward one side and heightening one side of the feeder head of the model after the model is boxed; adopting an upper layer of inner sprue and a lower layer of lower sprue to carry out stepped casting so as to form sequential solidification; and cooling and disassembling the model. The casting method can effectively avoid the cooling water pipe from being penetrated in a fusing manner during the casting process, avoid air gaps from being generated between the base body and the cooling water pipe, avoids refusion and recrystallization, accurately realizes the microfusion of the outer surface of the cooling water pipe, prolongs the service life of the cooling plate, further prolongs the service life of a metallurgical high-temperature kiln, saves production cost and improves the cooling effectand the mechanical performance of the cast steel cooling plate.

The invention relates to a molding method of an air inlet cover shell of a vacuum pump. The method comprises the following specific operation steps: (1) positioning a condensation coiled pipe in a mold cavity for forming a shell body by laminating a first sand core and a second sand core; (2) charging loose sand into the condensation coiled pipe and blocking hole parts of a medium inlet pipe and a medium outlet pipe of the condensation coiled pipe through end sockets; (3) putting a molding mold into a sand mold and leading molten iron into the mold cavity; covering a pipe body of the condensation coiled pipe through the molten iron and fusing; exhausting generated air through a pre-set air hole. By positioning the condensation coiled pipe through the first sand core and the second sand core, the pipe body is partially fused in the shell body and is integrally poured; the production efficiency of the air inlet cover shell is improved; meanwhile, the loose sand is charged into the condensation coiled pipe, so that the condensation coiled pipe is effectively prevented from being melted in a high-temprature fusing process; furthermore, the method is simple to operate, convenient to implement and low in cost.
