In.the. modus tollens .inference,.reasoning.is.as.follows:
If.A,.then.B.
Not.B.
Therefore,.not.A.
About.half.of.the.operators.decide.“not.A,”.and.the.remainder. decide.that.
nothing.follows..Operators'.choices.are.based.on.psychological.factors.that.
are.incorporated.within.the.operators'.judgments..Therefore,.psychological.
decision.making.is.deeply.related.to.the.operator's.judgment..The.values.in.
this.study.are.a.result.of.psychological.decision.making.by.the.operator.
A.plausible.value.is.obtained.by.random.sampling.of.the.interval.between.
0.and.1..The.random.number.is.generated.by.the.subtraction.of.the.nonse-
cure. random. number. from. the. secure. random. number,. which. relects. the.
summation. or. subtraction. in. the. zero-sum. method. of. game. theory. or. the.
network.effect..This.means.that.the.secure.situation.is.measured.by.the.sub-
traction. of. the. nonsecure. situation. in. a. random. process.. The. new. random.
number.is.called.a. random # factor ..Fuel.uncertainty.includes.several.factors,.
with.the.exception.of.fuel.handling.at.a.site..Nuclear.data.iles.indicate.how.
secure. operations. are. affected. by. reasonable. nuclear. data,. such. as. experi-
ment. and. experience. data,. which. could. be. related. to. accident. analysis.. In.
cases.of.power.production,.when.the.random.value.is.lower.than.the.refuel-
ing.factor,.the.value.is.0;.when.the.random.value.is.higher.than.the.refueling.
factor,.the.value.is.1..Therefore,.the.random.number.is.0.0.when.the.refueling.
is.done..This.means.that.the.secure.operation.is.very.risky..Power.production.
indicates.how.safe.operation.is.affected.by.the.refueling.period..The.model-
ing.is.seen.in.Figure 11.9.
Thermohydraulic. matters. involve. coolant. behavior. analysis. where. the.
energy.of.nuclear.fuel.is.transferred.to.the.heat.energy.of.the.coolant..This.
coolant.causes.the.turbine.to.move.and.generate.electricity..Thermohydraulic.
matters.have.four.factors:.coolant.temperature,.pressure.standard,.residual.
heat. removal,. and. boiling. capabilities. (see. Figure 11.9).. These. factors. are.
important.elements.of.the.heat.energy.of.the.coolant..Each.factor.is.quanti-
ied.using.a.Monte.Carlo.simulation.of.random.sampling.(see.Table 11.5)..For.
coolant.temperature,.when.the.random.value.is.lower.than.0.3,.the.value.is.
0;.when.the.random.value.is.higher.than.0.3,.the.value.is.2..The.0.3.value.is.
based.on.the.operator's.judgment..A.plausible.value.is.obtained.by.the.inter-
val.of.the.random.sampling.and.the.given.value.of.0,.1,.or.2.in.Table 11.5..For.
coolant.temperature,.pressure.standard,.residual.heat.removal,.and.boiling.
capabilities,. safe. operations. are. affected. by. reactor. power,. reactor. stability,.
emergency.cooling,.and.severe. accident,.respectively.. The.random.number.
is.generated.by.subtracting.the.nonsecure.random.number.from.the.secure.
random. number,. which. is. the. summation. or. subtraction. in. the. zero-sum.
method.of.game.theory.or.the.network.effect..The.new.random.number.is.
called.a.random.#.factor.
