The paper contains the results of numerical simulation of stainless steel melt motions on the surface of uranium dioxide. The investigations are performed for purposes of understanding of the fuel rod behavior during the core disruptive accident in the fast reactors. The systems of mass, energy and momentum conservation equations are solved to simulate melt motion on the surface of the fuel pin. Heat transfer and friction between melt and pin's surface and melt and coolant flow are taken into consideration. The dependences of mass of the melt and the features of the melt motion on coolant velocity and contact angle between melt and surface of the fuel rod are presented.

Pure Compression

The design philosophy of stainless steel requires appropriate recognition of observed material nonlinearity and pronounced strain hardening. A rational method namely, the Continuous Strength Method (CSM) has recently been to incorporate these effects but, in its current form, CSM yields better results for stocky sections. Individual capacities (i.e., pure compression and pure bending) for all types of sections and cross-section resistance against combined loading (i.e. compression plus bending) for RHS and I-sections can be predicted using CSM. The current research numerically investigates the performance of stainless steel lipped channel (LC) sections subjected to compression and bending. Nonlinear finite element models are developed and validated using available experimental results, and are consequently used to generate additional results for a wide range of cross-sections through parametric studies. Current CSM guidelines are used to propose a new set of formulations for predicting the section resistance of lipped channel sections subjected to combined loading.

This paper experimentally investigated the dynamic buckling behavior of AISI 303 stainless steel aluminized and as received intermediate columns.  Twenty seven specimens without aluminizing (type 1) and 75 specimens with hot-dip aluminizing at different aluminizing conditions of dipping temperature and dipping time (type 2), were tested under dynamic compression loading (compression and torsion), dynamic bending loading (bending and torsion), and under dynamic combined loading (compression, bending, and torsion) by using a rotating buckling test machine. The experimental results werecompared with tangent modulus theory, reduced modulus theory, and Perry Robertson interaction formula. Reduced modulus was formulated to circular cross-section for the specimens of type (1).The experimental results obtained showed an advantageous influence of hot-dip aluminizing treatment on the dynamic buckling behavior of AISI 303 stainless steel intermediate columns. The improvements based on the average value of critical stress were19.4 % for intermediate columns type (2) compared with columns type (1) under dynamic compression loading, 8.7 % for intermediate columns type (2) compared with columns type (1) under dynamic bending loading, and 16.5 % for intermediate columns type (2) compared with columns type (1) under dynamic combined loading.
