4.1 Introduction
A.possible.lunar.base.power.is.investigated.using.nuclear.energy..Nuclear.
ission. is. a. conceptual. design. for. nuclear. power. plants. (NPPs). in. a. very.
low.gravity.situation..The.National.Aeronautics.and.Space.Administration.
(NASA). has. developed. a. lunar. nuclear. power. reactor. (LNPR). concept. for.
the. manned. lunar. base,. which. could. be. realized. in. near. future.. The. tran-
sient.thermal.system.is.investigated.using.analytic.techniques.with.respect.
to. safety.. Conventional. methods. have. focused. on. functional. characteris-
tics.such.as.power.eficiency..In.this.chapter,.the.reliability.of.the.system.is.
examined.using.a.nonlinear.algorithm.due.to.the.uncertainty.of.the.lunar.
environment.
A.ission.surface.power.system.on.the.Moon.has.the.possibility.of.produc-
ing.40.kilowatts.of.electric.power,.which.can.supply.about.eight.houses.on.
Earth.(NASA.2009)..Figure 4.1.shows.NASA's.conceptual.design.of.a.ission.
surface. power. system. (NASA. 2010).. Figure 4.2. shows. a. front. view. of. a. is-
sion. surface. power. system. construction. that. is. based. on. the. NASA. design.
(Coulter.2010)..Figure 4.3.shows.the.LNPR..In.addition,.Figure 4.4.shows.the.
