COMPUTER DESCRIPTION--APPR-1 SIMULATOR
The APPR-1 Reactor is a pressurized water reactor havlng a fuel of low speciflc heat and water as prlmary coolant. The prlmary coolant loop delivers heat from the reactor to the steam generator. The secondary water in the steam genorator is converted to steam and then tsken to the turbine to drive the electrical generator. The slmulatlon cf thls system is broken down into three primary areas: the neutron kinetics ln the reactor whlch are necessary to generate the prlmary power function; the heat transfer in the reactor; and the heat transfer ln the steam generator. lnformatlon presented ls evaluated on the vlsual effect on the operator of the simulator. In many cases it is not necessary that the varlables being presented have the correct absolute value, provided that the form of the varlable is correct and the effect on the operator is the same as lf the correct absolute value ls being presented. This philosophy permlts the slmpllfocatlon of many equations. An important characteristlc of this simulator is that interlocks and safety clrcults are provided to dupllcate those in the reactor. lnterlock relays prevent control rod withdrawal in routlne operation'' if the prlmary coolant pumps are lnoperative or if the reactor period is less than ten seconds. ln the zero power'' mode, pump interlocks arc bypassed, but a scram will occur lf a 200-watt power level ts exceeded or the period drops below ten seconds.
