Penelitian ini ditujukan untuk mempelajari pengaruh radiasi gamma terhadap karakter polimer semi kristalin pada material insulasi kabel listrik tegangan rendah dari produk lokal, terkait penggunaannya di fasilitas dengan radiasi gamma tinggi. Sampel uji diiradiasi menggunakan perangkat Gamma Cell dengan dosis radiasi sebesar 25, 50, 100, 200, 400 dan 800 kGy. Derajat kristalinitas dan komposisi senyawa dari sampel uji dianalisis dengan uji XRD dan dikarakterisasi menggunakan FTIR. Berdasarkan uji XRD yang dilakukan, tidak teramati adanya perbedaan signifikan pada pola difraksi antara sampel uji non iradiasi maupun sampel uji iradiasi dengan variasi besar dosis. Hal ini mengindikasikan tidak terdapat perubahan fase mayor dari senyawa kristalin yang terkandung dalam sampel uji terkait. Adapun derajat kristalinitas dari sampel uji cenderung menurun seiring meningkatnya dosis radiasi yang diberikan. Hasil analisis FTIR menunjukkan adanya perbedaan transmittance yang fluktuatif antar sampel uji dengan dosis radiasi gamma yang berbeda juga dengan sampel uji non-iradiasi gamma. Adanya spektra yang semakin melebar di 400 kGy dan 800 kGy, pada wavenumber 3369 – 3370 cm-1, hal ini mengindikasikan adanya gugus O-H stretch. Pengujian lebih lanjut diperlukan untuk menguatkan identifikasi terhadap gugus fungsi, penentuan senyawa organik, maupun evaluasi terhadap karakter mekanik sampel uji yang sekaligus diperlukan untuk mengonfirmasi dugaan adanya gangguan terhadap asosiasi polimer-plasticizer.Kata kunci: Polimer semi kristalin, irradiasi gamma, derajat kristalinitas, perubahan kimia","PeriodicalId":23401,"journal":{"name":"Urania : Jurnal Ilmiah Daur Bahan Bakar Nuklir","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88791857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pendingin primer pada reaktor tipe PHWR dikendalikan secara kimia dengan penambahan asam borat dan LiOH untuk mengantisipasi korosi pada kelongsong bahan bakar yang menggunakan material zircaloy-2 (Zr-2.) Penelitian ini bertujuan untuk menganalisis pengaruh penambahan larutan H3BO3 dan LiOH terhadap jenis dan laju korosi material kelongsong bahan bakar Zr-2 dalam media air bebas mineral. Penambahan bahan H3BO3 dan LiOH pada pendingin reaktor PHWR adalah untuk pengendalian secara kimia. Uji korosi dilakukan pada temperatur kamar untuk menghilangkan pengaruh temperatur tinggi dan tekanan pada proses elektrokimia. Pada penelitian ini dilakukan pengamatan laju korosi material Zr-2 di dalam media air bebas mineral dengan penambahan H3BO3 dan LiOH dengan variasi konsentrasi. Hasil pengamatan, laju korosi Zr-2 menggunakan metode Tafel pada dalam media air bebas mineral dengan penambahan H3BO3 pada konsentrasi 10 ppm, 100 ppm, 500 ppm, 1000 ppm dan 2000 ppm diperoleh laju korosi masing masing 17,29 x 10-3 mpy, 18,51 x 10-3 mpy, 20,82 x 10-3 mpy, 22,71 x 10-3 mpy dan 23,29 x 10-3 mpy.

Few decades ago a large number of nuclear reactors were designed to use HEU as the fuel. But the use of  HEU is being discouraged since it can be used as a nuclear explosive material which makes its proliferation potential. Most of the HEU-fueled nuclear reactors in the world are either closed or converted into other types that have LEU fuel with 235U enrichment below 20%. To extend lifetime, LEU fuel with high density is developed. The change in fuel density from low to high will also change core neutronics and thermal-hydraulics of the reactor, and as a result, it affects the transient response of the reactor. This paper studies the effects of fuel density on reactivity coefficients and kinetic parameters of pebble bed reactor through several calculations with MCNP6 code combine with ENDF/B-VII.1 continuous energy cross-section nuclear data library. The overall calculation results show that the Doppler temperature coefficient (DTC) increases with increasing fuel density, but the moderator temperature coefficient (MTC) decreases due to hardening of neutron spectrum. Kinetic parameters such as effective delayed neutron fraction (βeff), prompt neutron lifetime(ℓ) and neutron generation time (Ʌ) which significantly reduced with increasing fuel density will strongly affect the reactor control and safety. The results of this work conclude that the selection of 9–15 g/cm3 fuel density should be considered carefully given that its effect on reactor controllability.Keywords: Fuel density, reactivity coefficients, kinetic parameters, MCNP6, ENDF/B-VII.1.","PeriodicalId":23401,"journal":{"name":"Urania : Jurnal Ilmiah Daur Bahan Bakar Nuklir","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73309344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The WIMSD-5B thermal reactor lattice cell code is used in many laboratories for research reactor calculations and power reactors. The program uses the Wigner-Seitz approximation for cell pin calculations. The approximation has been widely applied to the pin of UO2 cells and has shown good results in previous studies but can produce incorrect results when used for pin cells in MOX fuels. This paper investigates the use of the WIMS-5B code to calculate the neutron multiplication factor and depletion for MOX fuel pin cells. Calculations were performed using the WIMSD-5B code updated with the ENDF-BVIII.0 library. The outer scattering boundary condition was used to overcome the effect of the Wigner-Seitz approach on the lack of MOX fuel. Results of this study indicates that most of the results obtained using ENDF-BVIII.0 are better than ENDF-BVII.1, and this is in line with expectations. The difference in the maximum k-inf value obtained from this library occurs in the fuel that has the greatest enrichment. On the other hand, the addition of the outer scattering limit improves the results obtained using ENDF-BVIII.0, causing a slight improvement for other libraries. This shows that by using appropriate libraries and the addition of the scattering outer limit, the Wigner Seitz approximation for the MOX pin cell pins in WIMS-D5 can yield quite accurate results.Keywords: Wigner-Seitz approximation, WIMS-D5 code, MOX fuel, Doppler reactivity.","PeriodicalId":23401,"journal":{"name":"Urania : Jurnal Ilmiah Daur Bahan Bakar Nuklir","volume":"93 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79621545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The high entropy alloy of AlxCrFeNiM (with x = 1, 1,2 and 1,4; M = Mo and Zr) was successfully synthesized using powder metallurgy technique with sintering process at 1000 oC in an inert atmosphere. These alloys were designated as fuel cladding for research reactor with high U-density fuel such as U-Mo. One of the critical in-service properties of nuclear fuel cladding is its corrosion behavior. In this study, some properties of the HEA of AlxCrFeNiM such as the phases, microstructures, hardness, and corrosion resistance in 3 wt.% NaCl solution at room temperature were investigated. The results show that the phases in the HEA of AlxCrFeNiMo are FeNi, AlNi and Mo. The HEA of AlxCrFeNiZr has more complex phases compared to the AlxCrFeNiMo. The microstructure of HEA samples show  fine grains with some micropores that imperfect the solidification during the sintering process. The hardness value of the HEA of AlxCrFeNiMo has a trend of decreasing as the x value increases. The opposite trend occurs to the HEA of AlxCrFeNiZr that the hardness value increases with increasing x value. The lowest hardness value is Al1.4CrFeNiMo at 262.2 HV, and the highest hardness value of Al1.4CrFeNiZr is at 756.7 HV. The corrosion rate of the AlxCrFeNiMo does not show a specific trend with increasing x value; however,  the AlxCrFeNiZr shows decreasing value with increasing x value. The lowest value for the all-HEA samples is 0.20 mmpy for the Al1.4CrFeNiZr.
