Abstract
The CHASHMA Nuclear Power Plant unit 1 is known as CHASNUPP-1. The CHASNUPP-unit 1 is a 996 MWth intermediate type pressurised water reactor that began commercial operation in June 2000 in Pakistan. The CHASNUPP unit 1 is a conventional two loop PWR operated by the Pakistan Atomic Energy Commission (PAEC). The radiological source term of CHASNUPP-1 has been evaluated and compared with the advanced modular reactor (SMART) and KORI-1 reactor. For this purpose, modelling and simulation has been carried out in MATLAB. a kinetic model has been developed to carry out the simulation of the release of radionuclides. The core and coolant activity of CHASNUPP-1 is compared with the similar type reactor KORI-1. The developed model uses the ORIGEN 2.2 core inventory as a subroutine. The coolant inventory has been evaluated with 0.25% fuel damage and compared with SMART and KORI-1 reactor.
Kurzfassung
Der CHASHMA-Kernkraftwerksblock 1 ist international als CHASNUPP-1 bekannt. Der CHASNUPP-Block 1 ist ein mittelgroßer Druckwasserreaktor mit einer thermischen Leistung von 996 MWth, der im Juni 2000 in Pakistan den kommerziellen Betrieb aufgenommen hat. Der CHASNUPP-Block 1 ist ein konventioneller Zweikreis-DWR, der von der Pakistan Atomic Energy Commission (PAEC) betrieben wird. Berechnungen zur erwartenden Strahlenbelastung bei Kühlmittelverluststörfällen in CHASNUPP-1 werden in diesem Beitrag vorgestellt. Dazu wurde mit dem Programm MATLAB eine Modellierung des KKW erstellt und die Szenarien berechnet. Für die Simulation der Freisetzung von Radionukliden wurde ein kinetisches Modell entwickelt. Die Kern- und Kühlmittelaktivität von CHASNUPP-1 wird mit bestehenden Analysen zum ähnlichen Reaktor KORI-1 sowie mit dem fortschrittlichen modularen Reaktorkonzept SMART verglichen. Das entwickelte Modell verwendet das ORIGEN 2.2 Kernprogramm als Unterprogramm.
