These articles have been peer-reviewed and accepted for publication in IJNEST, but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.


Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Burn/breed: a wavelet-based nuclear fuel burnup and decay heat code   Order a copy of this article
    by Hesham Nasif 
    Abstract: Burn/breed is a code designed to aid in the analysis, prediction and optimisation of fuel burnup performance and decay heat calculation in a nuclear reactor. The code uses the output parameters generated by the Monte Carlo neutronics codes to determine the isotopic inventory as a function of time and power density. Burn/breed directly uses the neutron absorption tally/reaction information generated by Monte Carlo code for each nuclide of interest to determine the nuclide inventory. When the isotope inventories have been calculated for a specific reactor operation and cooling period, the decay heat can be derived. Beside the U-235 and Pu-239 decay chains, the code includes the U-233 decay chain to manage the possible scenarios for using thorium in a nuclear fuel cycle. This paper describes the theoretical basis of this code, and shows the results of the code for two test cases. The results show good agreement with other codes for the first test case and with the experimental results for the second test case.

  • Coupled channel calculations using semiclassical and quantum mechanical approaches for light and medium mass systems   Order a copy of this article
    by Fouad A. Majeed, Khalid H. H. AlAteah, Malik S. Mehemed 
    Abstract: A semiclassical approach and a full quantum mechanical approach have been used to study the effect of channel coupling on the calculations of the total fusion reaction cross-section 𝜎𝑓𝑢𝑠 , the fusion barrier distribution 𝐷𝑓𝑢𝑠 and the reaction probability (prob.) for the light systems (4He+233U, 13C+48Ti) and the medium system (46Ti+46Ti). The semiclassical approach used in the present work based on the method of the Alder and Winther for Coulomb excitation. The results obtained from our semiclassical and full quantum mechanical calculations are compared with the available experimental data. The semiclassical calculations agree reasonably with the full quantum mechanical treatment, and they were able to reproduce the experimental data in detail for the total fusion reaction cross-section 𝜎𝑓𝑢𝑠 , the fusion barrier distribution 𝐷𝑓𝑢𝑠 and the probability of the reaction.
    Keywords: semiclassical treatment; quantum treatment; breakup reaction; light systems; medium systems.

  • Testing in sodium and qualification of the bearings used in inclined fuel transfer machine of prototype fast breeder reactor   Order a copy of this article
    by S. C. S. P. Kumar Krovvidi, Punniyamoorthy R, Sreedhar B K, Chandramouli S, Padmakumar G, Raghupathy S, Selvaraj P 
    Abstract: Track roller type double row deep groove ball bearings made of SS-440C material are used in the inclined fuel transfer machine (IFTM) of the prototype fast breeder reactor (PFBR). The bearings are unlubricated hence need to operate under sodium and subsequently in cover gas at 50oC. The number of rotations of the bearings during 40 years of the reactor operation is 1.15 million. This paper presents the experiment carried out to examine the performance of the bearings used in IFTM under simulated conditions as in the reactor. The bearing was initially tested in air, in argon and in sodium at 200oC. It is observed that the frictional torque value of the sodium wetted bearing in cover gas at 50oC is increased owing to solidified sticking sodium on the bearing. Wear in the bearings is significant after 1,065,000 rotations. This paper presents the scheme of testing of the bearing, details of the test facility, test results and discussion. The frequency of replacement of the bearings in IFTM of PFBR is arrived at based on the experiment. This experiment gave better insight into the use of bearings for under-sodium applications.
    Keywords: bearings; SS 440C; testing in sodium; SFR application.
