How successful were the human torpedoes, developed by the Japanese during the WW2?
It was a disappointment. Kaitens had a very limited diving depth, which in turn limited the diving depth of the host submarine. This is one of several factors blamed for the very poor survival rate of submarines armed with kaitens: eight submarines being lost for the sinking of only two enemy ships and damaging several others.

What is the main reason to use nuclear reactor on a submarine?
It needs no oxygen. Nuclear reactor requires no oxygen for combustion and emits no exhaust gas. It gives the submarine the ability to operate submerged at high speeds, for unlimited periods, dependent only on the endurance of its crew. Nuclear power revolutionized the submarine, finally making it a true "underwater" vessel, rather than a "submersible" craft.
In World War II, a Nazi submarine U-1206 was accidentally sunk by?
An improperly operated toilet. On 14 April 1945, while U-1206 was cruising at a depth of 200 feet, misuse of the new toilet caused large amounts of water to flood the boat. The leak flooded the submarine's batteries causing them to release chlorine gas, leaving him with no alternative but to surface. Once surfaced, U-1206 was discovered and bombed by British patrols, forcing Schlitt to scuttle the submarine. One man died in the attack, three men drowned in the heavy seas after abandoning the vessel and 46 were captured.
