is.much.more.unstable;.it.is.the.summation.of.neutronics.matters,.thermo-
hydraulic.matters,.and.safeguard.matters.as.a.function.of.the.time.interval.
(months)..The.maximum.value.of.Figure 11.11(d).is.12.0.in.month.3.and.the.
minimum.value.is.1.0.in.months.18.and.54..This.illustrates.the.secure.power.
operation.situation..The.success.of.power.uprates.increases.to.a.value.that.is.
12.times.higher.than.the.lowest.value.
The. vertical. axis. indicates. the. relative. values. of. the. quantiications..
Comparisons.between.the.values.of.interest.are.used.for.the.results.of.the.
simulations..Using.the.results,.the.operator.can.prepare.for.possible.terror-
ist.attacks..For.example,.using.Figure 11.11(d),.the.operator.should.beware.
of.terror.incidents.when.the.values.are.lowest,.such.as.the.value.of.1.0.in.
months. 18. and. 54.. In. addition,. this. study. provides. dynamic. simulations,.
so. it. is. possible. to. make. much. more. accurate. real-time. measurements. by.
changing.the.time.interval.from.months.(of.this.study).to.hours.or.minutes.
