Abstract

Reduce the pressure and reheating CNG, created a tool called a pressure reducing system (PRS) which consists of a pressure reducing regulator, heating CNG or we call this section with heat exchanger and measuring tools or gas meter. In connection with this task, will be discussed on the heat exchanger in the heat of this CNG. In this study, a survey was conducted on the heat exchanger Pressure Reducing System (PRS) is installed with a capacity of 200 m3/h, while the use of CNG for the production process is 150 m3/h. CNG temperature after coming out of the PRS read on the thermometer is at 50ºC. From these data it can be concluded that the heat exchanger is greater than the required capacity. In order to get heat exchanger in accordance with the capacity of 150 m3/h will be redesigned according to the capacity. From the data obtained it can be concluded that the pressure reducing system capacity greater use of capacity will value of higher effectiveness at about 90%. As for usage as needed obtained effectiveness of 70%. The advantages that can be drawn is that the efficiency in terms of construction materials and a smaller space than the existing PRS.

Abstract

Safety is an issue that is of considerable concern in the design, operation and development of a nuclear reactor. Therefore, the method of analysis used in all these activities should be thorough and reliable so as to predict a wide range of operating conditions of the reactor, both under normal operating conditions and in the event of an accident. Performance of heat transfer to the cooling of nuclear fuel, reactor safety is key. Poor heat removal performance would threaten the integrity of the fuel cladding which could further impact on the release of radioactive substances into the environment in an uncontrolled manner to endanger the safety of the reactor workers, the general public, and the environment. This study has the objective is to know is profile contour of fluid flow and the temperature distribution pattern of the cooling fluid is water (H2O) in convection in to SMR reactor with fuel sub reed arrangement of hexagonal in forced convection. In this study will be conducted simulations on the SMR reactor core used sub channel hexagonal using CFD (Computational Fluid Dynamics) code. And the results of this simulation look more upward (vector of fluid flow) fluid temperature will be warm because the heat moves from the wall to the fluid heater. Axial direction and also looks more fluid away from the heating element temperature will be lower.
