“…This calculation consists of two steps: the pebble Dancoff factor calculation and two-step slowing-down calculations per pebble type and burnup group. The pebble Dancoff factor (not TRISO Dancoff factor) is determined using the dual sphere model of Ji's method [9] for each spectral zone. Once the Dancoff factor of each pebble is obtained, two-step slowing-down calculations are performed for each pebble of fresh pebble type and each burnup group [23]: the first step for the double heterogeneity treatment for TRISO particles and the second step for the pebble, in which the fuel zone with TRISO particles is homogenized using the flux-volume weighting obtained from the first step.…”

“…Versuchs reaktor atau Experimental Pebble Bed Reactor (AVR) merupakan reaktor nuklir jenis HTGR dari Jerman yang dibangun pada tahun 1960 dan berhenti beroperasi pada tahun 1988 [5,6]. Jenis bahan bakar nuklir dari reaktor AVR adalah sama dengan RDE yaitu bahan bakar bentuk pebble (bola) yang berlapis TRISO [7][8][9][10]. Oleh karena itu dalam penelitian ini dipelajari BBNB dari reaktor AVR yang dapat menjadi salah satu kontribusi penting untuk melengkapi data penelitian berkenaan dengan sistem penyimpanan BBNB dari RDE yang amat diperlukan.…”

“…Keempat lapisan tersebut berfungsi sebagai bejana bertekanan yang berintegritas tinggi dan memiliki kemampuan retensi yang sangat tinggi terhadap hasil fisi serta masingmasing lapisan mempunyai fungsi yang spesifik. Di antara keempat lapisan tersebut, lapisan yang paling penting dalam partikel jenis TRISO adalah lapisan SiC yang berfungsi memberikan sebagian besar kekuatan struktur dan stabilitas dimensi serta sebagai penghalang utama terhadap pelepasan hasil fisi yang apabila tidak ditahan akan menembus lapisan PyC dan akan mengkontaminasi sistem pendingin primer [8][9][10][11]. Gambar 1 menunjukkan partikel bahan bakar Pebble yang berlapis TRISO.…”

“…Afterward, a new resonance treatment method [3] for DH fuel was proposed based on the equivalence theory with the intermediate resonance (IR) approximation [4,5] and the Dancoff factor [5] for the particle fuel without coating layer. Kim [6] extended the method to take the coating layer of TRISO into account using the analytical Dancoff factor for TRISO particle fuel [7].…”
