Abstract

In this work, steam cycle from a nuclear power plant is explored in order to increase efficiency and electric power output. A thermal source in the form of a HTGR-10 concept is considered. The power conversion unit of HTGR-10 consists of steam generator, turbine, condenser, pump, and connecting pipes. Helium is used as the core coolant and the working fluid for power conversion unit is water/steam. The proposed thermodynamic process modification has been evaluated for regenerative steam power cycle of this reactor. The scope of study covered regenerative steam cycle with two tanks including feed water tank and intermediate feed water tank. The evaluation analyzes the effect of pressure, efficiencies of turbine and pumps, and tanks against thermal efficiency. The Cycle-Tempo software is used to simulate and optimized this effect on steam cycle based on HTGR-10. The results indicate improvements of as much as 2.65 % in thermal efficiency and 0.271 MWe in electric power.

Abstract

CYLINDRICAL SHELL ANALYSIS OF REACTOR PRESSURE VESSEL FOR RDE. The present study deals with the design process analysis of cylindrical shell for Reactor Pressure Vessel (RPV) of Reaktor Daya Eksperimental (RDE). The RDE is prepared by BATAN for nuclear technology provider in Indonesia. RPV is a container for confining helium gas at elevated pressure and temperature (circa 700 °C). In RPV operation, mechanical stresses act as in consequence of internal pressure (3 MPa), external pressure, and different loads due to dead weight and helium content load. Therefore, if the RPV could not retain its material strength or exceed the maximum allowable shear stress it will cause failure. The applications and validity of Fortran code (RPV_RDE.exe) for the design analysis are represented by two simulation cases, which indicate good calculation results of design outputs compared to analytic solutions. Design outputs have met the safe requirements for the minimum wall thickness of cylindrical shell in upper portion of 60 mm and in lower portion of 100 mm, respectively.
