[en] The purpose of this standard is to provide criteria for the qualification of reference reactor physics measurements obtained from subcritical (including non-multiplying), critical and other experiments for the purpose of verifying nuclear design and analysis methods. It provides guides for documentation of reference data and independent expert review of proposed reference reactor physics data to assure compliance with the criteria of this standard

[en] By making a deliberate use of physical laws it is possible to build fission reactors with a high level of inherent safety. This safety, which is independent of human intervenience or of active safety systems, protects man against the nuclear reactor but also the reactor against man. This article discusses the physical principles of a possible new generation of nuclear reactors, for which inherent safety is the starting point for the design. (author). 3 refs.; 6 figs

[en] The object of the work reported is to develop educational computer modules for all aspects of reactor physics. The modules consist of a description of the theory, mathematical method, computer program listing, sample calculations, and problems for the student, along with a card deck. Modules were first written in FORTRAN for an IBM 360/75, then later in BASIC for microcomputers. Problems include: limitation of equipment, choice of format for the program, the variety of dialects of BASIC used in the different microcomputer and peripherals brands, and knowing when to quit in the process of developing a program

[en] In a study of the perturbative effects of a slight internal interface shift within a reactor, the authors came across an anomaly in the use of standard first-order perturbation theory. The purpose of this work is to bring this interesting anomaly to the attention of the reactor physics community. On the more practical side, the discussion shows that the use of standard first-order perturbation theory gives an incorrect result for one particular class of problems. The source of this error is identified and the correct perturbative formula for this type of problem is derived. 3 refs

[en] This letter points out that the classical first-order perturbation formula will not correctly treat the case of a slight internal interface shift. Indicates that the traditional derivation, equation, and interpretation of classic first-order perturbation theory are all entirely correct if the perturbed problem differs from the unperturbed one by a material property perturbation

[en] The 2D/1D fusion method (2D/1D method) is becoming a standard transport method for whole-core calculations, which reduces the group condense and assembly homogenization approximations in the conventional two-step reactor physics calculations. In most 2D/1D codes, a pin is chosen as a 1D calculation domain, which assumes that the axial leakage of the pin is flat on top/bottom surfaces. Similar to the axial leakage, the radial leakage of every 2D plane also introduces several approximations along axial direction for the 1D calculation. This paper studied the error introduced by both axial and radial leakages, and proposed a leakage reconstruction method according to the error analysis for the 2D/1D fusion method, in which MOC is applied to the radial 2D calculation and the Sn diamond difference method is used for the axial 1D calculation. Several cases are tested to show the performance of this leakage reconstruction method especially when the leakage term is significant.
