A fuel tank for storing an alternate fuel and providing the fuel to an internal combustion engine includes: an inner shell with an internal cavity designed to store fuel; an outer shell configured and positioned relative to the inner shell such that an interstitial volume is created between the inner and outer shells; and a heating unit positioned in the interstitial volume. In some embodiments, the interstitial volume is filled with air; in other embodiments, the interstitial volume is filled with a thermally insulative material.

The invention relates to a spent fuel storage pool bottom scrubbing device comprising a travel system arranged on the pool bottom; the travel system comprises a seal housing, and a filtering system is arranged in the seal housing; a suction system is arranged outside the seal housing; the top of the suction system penetrates the seal housing and is connected with a liquid inlet arranged on the top of the filtering system; an evacuation system is arranged in the seal housing, a liquid inlet end of the evacuation system is connected with a liquid outlet arranged on the bottom of the filtering system, and a liquid outlet end penetrates the seal housing and is connected with the spent fuel pool. The pollution discharge device can prevent radioactive substance from hurting human body; the scrubbing device has less dynamic components, and only uses one power supply driving so as to realize sucking and filtering functions in traveling on the poll bottom; the scrubbing device can fast replace a filter core in the water, realizes safety unkeep and water leave evacuation functions, is simple in structure, and high in reliability.
