4.4 Results
The.result.of.the.dynamic.simulation.is.obtained.as.the.relative.value..The.
reactor.is.assumed.to.start.in.2020.as.part.of.a.possible.plan.to.construct.a.
lunar. base.. The. primary. system. of. the. LNPR. is. a. pressurized. water. reac-
tor. (PWR). with. the. current. commercial. power. utility. technology.. There. is.
another. option. where. the. reactor. primary. loop. is. a. gas-cooled. reactor,. but.
this.is.not.commercialized.yet.and.is.one.of.the.generation.4.reactor.concepts..
This.reactor.is.assumed.to.produce.40.kilowatts.of.electric.power.
In.the.simulation,.the.time.period.is.30.years,.from.2020.to.2050..The.time.
step. is. 0.25. month,. which. is. one. week;. that. is,. the. simulation. cycle. is. 0.25.
month..The.quantiication.is.repeated.every.week..In.Figure 4.13,.the.possible.
performance. of. the. long-term. cooling. increases. to. 28.4763. in. 2049.. This. is.
