“…Up to now, rectangle and hexagon modular ray tracing has been developed in SHARK with the established method (Cho et al, 2008;Chen et al, 2018). In the future, the long characteristic method (Suslov, 2001) will be added for complicated geometry cases without regular assembly structure.…”

In order to establish the next-generation reactor physics calculation method based on the numerical nuclear reactor technology and realize high-fidelity modeling and calculation, a new numerical nuclear reactor neutronics code SHARK is developed. The code is based on the direct transport method with construct solid geometry (CSG) method, advanced subgroup resonance method, direct transport MOC method in rectangle and hexagonal geometry, large-scale parallel, and CMFD acceleration method. The C5G7, macro BEAVRS and VERA benchmarks are verified to show the accuracy of the code and method. Numerical results show good accuracy and calculation performance of SHARK, and the direct transport method can be adopted on numerical nuclear reactor calculation.

“…Method of 16 The preferences of 19 F(n,α) 16 N nuclear reaction use for radiation control channels test on water cooled power reactors are analyzed. The new measurements for more accurate determination of 19 F(n,α) 16 N reaction cross section energy dependence have been carried out. A set of new methods for background reducing and improvement of events determination reliability was developed.…”

“…Алгоритм проверен на аналитической задаче с линейно анизотропным рассеянием и на многогрупповой тестовой задаче. В расчетах использовались основанная на ме тоде характеристик программа MCCG3D [15][16][17] на исходных групповых сечениях и программа метода Монте Карло VEGA [18], согласованная по представлению констант с MCNP.…”
