    Nuclear accidents or nuclear leakage is the most earedimpact beond the bene4t o nuclear energ or humans.

    Nuclear meltdown occurs when the nuclear power sstemor component ailure causing the reactor core can not be

    controlled and cooled so that the nuclear uel isprotected 3 which contain uranium or plutonium andradioactive 4ssion products 3 began to heat up and leak.

    5 leak is considered ver serious because o the possibilitthat the reactor containment begins to ail, releasing

    radioactive and to#ic elements into the atmosphere andthe environment. $rom the development standpoint, a

    leak can cause severe damage to the reactor, and thepossibilit o total destruction.
