Abstract

The advancement of computational technology has significantly contributed to the development of physics, particularly in modeling complex systems such as nuclear power generation. Electricity production in nuclear power plants is highly influenced by the number of active reactors and the dynamic behavior of the fissionprocess. In this study, the dynamics of electricity production are modeled using numerical approaches, specifically the Euler and Runge-Kutta methods, which are effective in solving nonlinear differential equations. Both methods are applied to analyze changes in electrical energy over time in relation to variations in the number of operating reactors. The modeling results indicate a difference in accuracy between the two methods, with the Runge-Kutta method yielding more stable and precise results compared to the Euler method. This activity aims to enhance students' skills in applying computational methods to quantitatively and systematically understand the dynamics of nuclear energy systems.

ABSTRAK

Kemajuan teknologi komputasi telah memberikan kontribusi besar dalam pengembangan ilmu fisika, khususnya dalam pemodelan sistem yang kompleks seperti pembangkitan listrik tenaga nuklir. Produksi listrik pada pembangkit nuklir sangat dipengaruhi oleh jumlah reaktor aktif dan dinamika proses reaksi fisi di dalamnya. Pemodelan dinamika produksi listrik ini dilakukan dengan pendekatan numerik menggunakan metode Euler dan Runge-Kutta, yang mampu menyelesaikan persoalan diferensial non linier secara efisien. Dalam studi ini, kedua metode digunakan untuk menganalisis perubahan energi listrik terhadap waktu berdasarkan perubahan jumlah reaktor aktif. Hasil pemodelan menunjukkan perbedaan tingkat akurasi antara kedua metode, di mana metode Runge-Kutta memberikan hasil yang lebih stabil dan mendekati solusi eksak dibandingkan metode Euler. Kegiatan ini bertujuan untuk melatih kemampuan.
