Perhitungan sel bahan bakar teras reaktor PWR telah dilakukan dengan menggunakan program komputer WIMSD-5B. Perhitungan dilakukan untuk mengetahui karakteristik neutronik bahan bakar teras reaktor PWR dengan variasi daya. Karakteristik neutronik diketahui dengan memperoleh konstanta makroskopik seperti k-inf, koefisien difusi, tampang lintang serapan dan fisi. Generasi sel bahan bakar dilakukan dengan 69 grup energi neutron pada program transport satu dimensi (WIMSD-5B) menggunakan ENDF-BVII.1 data file. Sel satuan diperhitungkan pada perangkat elemen bakar dengan model cluster dengan susunan square pitch, kemudian dihitung dimensi satuan selnya. Satu satuan sel terdiri dari satu satuan bahan bakar dan moderator. Dari satu satuan sel ekivalen tersebut diperoleh data dimensi sel sebagai data masukan program WIMSD-5B yang dikenal dengan annulus. Bahan bakar yang digunakan adalah UO2 dan bentuk geometrinya pin cell bahan bakar. Hasil perhitungan faktor multiplikasi tak terhingga sel teras PWR yang dihitung dengan menggunakan paket program WIMSD-5B adalah 1,302338 dan fraksi bakar 37,12 GWD/TU. Dari hasil perhitungan dapat dinyatakan bahwa nilai faktor multiplikasi tak terhingga, konstanta difusi, tampang lintang serapan dan nu-fisi sangat dipengaruhi oleh bentuk model yang digunakan.Kata kunci: bahan bakar, teras PWR, WIMSD-5B, energi neutron, konstanta makroskopik

A recent study by Baltiansky, Craig, & Jost (2020) tested two hypotheses related to system justification and the perception of stereotypical humor. They reported to have found evidence for a cross-over interaction, with judgments of jokes being contingent on a combination of the social status of the targets of jokes and raters’ system justification motivations. Here, we discuss the original analysis, presentation, and interpretation of the data in Baltiansky et al. (2020), before presenting a re-analysis of the authors’ shared data file. We show that the framing of claims such as “high system-justifiers found jokes targeting low-status groups (e.g., women, poor people, racial/ethnic minorities) to be funnier than low system-justifiers did” (p. 1) are misleading in their framing. Instead, our re-analyses suggest that ideological differences in joke perception are driven primarily by those scoring low on the system justification motivation rating jokes about ostensibly low-status groups as less funny than jokes about other social groups.
