船舶原子爐의 硏究開發에 關한 考察 = A study on the Development of Marine Reactor

다국어 초록 (Multilingual Abstract)

(1) Nuclear power is currently requested as substitute energy source of a fossil fuel and with a part of an anti-pollution policy in the earth.
According to data in Norway, which was handed in 29th MEPC-IMO Marine Environment committee-in March of 1990, the pollution levels for specific gases include 2% for CO2 4% for SOx and 7% for NOx from international ships, that could make the earth warm and also acidic rain. And it's also important that the emissions of bilge water from ship pollute the sea.
(2) The plant process quantity in nuclear ship can be influenced by the vibration of ship under stormy weather.
① The reactor power, temperature and pressure, the amount of flowing water level in plant process are changed at large.
Especially a water level in steam generator and a pressurizer can be influenced largely by water surface and two-phase flow condition.
According to a frequency-explanation of ship's vibration, in ship's heaving, rolling and pitching, heaving of the ship affects the fluctuation of water level largely in proportion to acceleration of up and down motion.
② The load variation which is caused by R.P.M of the main propulsion engine and its power in a ship managed by engineer's intention or natural condition makes much vibration in the ship.
The periodical vibration of propeller and its racing also cause much vibration in the ship.
(3) The vacuum of main condenser can be influenced by the temperature of sea water which is approximately from 5℃ to 30℃.
The lower temperature of sea water marks, the higher vacuum-rate marks, which makes engine power increase.
(4) As stated above, nuclear engineering should concentrate on study about more safe and easy-handling and economical marine reactor.
The government should establish faithfully the policy about substitute energy.
