Abstract

A system of monitoring turbidity levels in real time using an LDR sensor has been designed and implemented. This study aims to characterize the LDR sensor and subsequently the results are used as a basis in the application of the deterioration system design for water turbidity levels. The characterization results show that the LDR sensor has a linearity of 90.86% and sensitivity of 0.0082 mV per lux. After being applied in measuring instruments the light intensity of the sensor has a precision level of 92.58% and the level of accuracy of the measurement results is an average of 87.89%. Based on the results of the design that has been carried out this instrument is able to turn on the water pump for the purification process automatically when the intensity of back scattering is less than 72 lux

Abstract

The Research of the supercritical water reactor (SCWR) core design of the cylindrical core model (r, z) using the SRAC program has been done. The SRAC basic code was PIJ and CITATION. PIJ was used to calculate the fuel level and CITATION was used to calculate the reactor core level. The calculation of the reactor core has been done on the 1/4 cylinder core (r, z) and the geometry of the fuel cell was the cylindrical cell. Reactor fuel material was thorium burned 40 GWd/t and 30 GWd/t. The neutron parameters in this research were fuel enrichment, burn up, reactor core size, reactor core configurations, multiplication factor, and power density distribution. Multiplication factor (k-effective) in this research was 1.000004, which is reactor was in a critical condition. The reactor core in critical condition had the size of radius (r) was 130 cm, height (z) was 270 cm and fuel enrichment 2.8262%. The maximum power density was 130.0808 Watts /cm3 which was located at a radius of 25 cm and 135 cm high. The peak power factor in the radial direction was 1.6063 and the peak power factor in the axial direction was 1.3189.
