2.1 Introduction
Nuclear. spent. fuel. waste. management. using. ion. beam. injection. has. been.
investigated..Ion.beam.injection.can.make.the.form.of.the.container.for.the.
nuclear.waste.safer.for.the.proposed.radiation..The.investigation.is.performed.
at.the.nanoscale.level..The.computer.simulation.can.predict.the.reliability.of.
the.industrial.application.in.several.outputs.such.as.ion.distribution,.range,.
ionization,. phonons,. recoiled. energy,. and. whether. there. will. be. a. damage.
event..Currently,.it.is.very.dificult.to.ind.a.nuclear.waste.repository.site.for.
permanent. waste. disposal. in. some. countries. including. the. United. States..
Therefore,. it. is. important. to. make. a. strong. container. material. for. nuclear.
waste. radiation. shielding. for. the. interim. period. until. a. repository. can. be.
selected.and.agreed.upon.by.the.community.and.the.government..Nuclear.
waste. containers. should. provide. protective. barriers. against. physical. and.
chemical. stresses. during. transportation,. interim. storage,. and. disposal.. In.
the.case.of.high-level.waste.(HLW),.separated.casks.are.used.for.transporta-
tion,.and.special.emphasis.is.given.to.the.disposal.containers.to.ensure.long-
term.isolation.of.the.waste..The.key.performance.parameter.is.the.resistance.
to.environmental.attack.(chemical.performance)..Mechanical.performances,.
thermal/neutronic.performance,.compatibility.with.other.materials,.fabrica-
bility,.and.previous.experience,.as.well.as.cost,.are.also.taken.into.account.
