In this paper, 3D numerical analysis of unsteady flow forces acting on the measuring sheath of steam temperature is presented. According to that purpose, the CFD (Computation Fluid Dynamic [1]) approach has been used. The nonstationary of fluid acting on the measuring sheath such as: Strouhal frequency, amplitude of pressure, structure of vortex, peak of pressure, field of pressure, field of velocity etc. are studied analytically and numerically. Examined two cases of flow with changing both temperature, pressure and mass flow rate (operating daily and night in the unit with capacity of 373 MWe). The main aim of the paper is to refer to the standards of ASME PTC 19.3 TW-2010 [2]. We should add that a large number of experimental and numerical studies [3-7] of the wake behind the obstacles and vortex induced vibration have been performed. In accordance with the standards ASME PTC 19.3 TW-2010 the possibility of entry into resonance has been examined.
