system. supplies. the. basic. matter. to. build. the. LNPR.. The. thermohydraulic.
two-phase. system. in. space. has. been. devised. by. Park. and. Sunada. (2008)..
The. vapor. compressor-driven. hybrid. two-phase. loop. was. developed. for.
high-temperature.application..The.evaporator.used.passive.capillary.pump-
ing.to.feed.a.well-balanced.liquid.for.thin.ilm.boiling.heat.transfer,.which.
improves.the.high.heat.lux.capability..Several.results.were.demonstrated.in.
the.small-scale.prototype..This.was.the.fundamental.thermal.behavior.that.
was.incorporated.with.heat.transfer..It.is.suggested.that.the.safety.aspects.of.
system.operations.need.improvement..For.the.dynamic.risk.assessment,.Siu.
(1994).and.Belhadj.and.Aldemir.(1996).performed.computational.simulations.
on.the.system.safety.
The. simulations. using. system. dynamics. (SD). are. constructed. for. time-
dependent.quantiication.of.management.for.the.safety.assessment..Section.
4.3. explains. the. method. of. the. study.. The. calculation. for. the. modeling. is.
shown.in.Section.4.4..Section.4.5.describes.the.results.of.the.study..There.are.
some.conclusions.in.Section.4.6.
4.2 Method
System.dynamics.was.created.by.Dr..J..Forrest.at.the.Massachusetts.Institute.
of.Technology.(MIT).for.quantiication.of.systematic.situations..Applications.
for. nonlinear. characteristics. of. social. and. economical. systems. have. been.
studied.. Quantiication. is. accomplished. by. testing. and. modeling. the.
complex.features.in.the.dynamic.scenarios.in.the.areas.of.interest..Feedback.
on.the.event.and.the.time.step.are.particular.characteristics.of.SD,.where.the.
event.lows.are.expressed.in.a.nonlinear.algorithm..Quantiication.is.done.by.
Monte.Carlo.simulations.of.the.deined.algorithm.
M.. Radzicki. described. SD,. which. is. a. powerful. methodology. and. com-
puter. simulation. modeling. technique. for. understanding,. framing,. and.
discussing. complex. issues. and. problems. (Radzicki. and. Taylor. 1971).. It. is.
designed.for.managers.to.improve.their.understanding.of.complex.issues,.
and. is. applicable. in. all. kinds. of. policy. and. design. areas.. SD. can. be. used.
to. investigate. how. and. why. complex. real-world. systems. behave. the. way.
they.do.during.a.speciied.time.period..Improved.understanding.can.lead.
to. implementation. of. more. effective. policies.. The. most. important. thing. is.
the.dynamic.behavior.of.a.system,.where.the.operator.tries.to.identify.pat-
terns.of.behavior.exhibited.by.particular.system.variables,.and.then.builds.
a. model. based. on. the. characteristics. of. those. patterns.. In. SD. modeling,.
single-. and. double-arrow. lines. are. used. for. the. purpose.. Lines. are. used.
for. the. event. lows. and. time. lows.. The. dynamic. behavior. of. a. system. is.
manipulated. by. SD. using. its. key. physical. and. information. lows,. stocks,.
