Abstract
The Nuclear Power Plant Accident in Fukushima, Japan in 2011 became a valuable lesson in the safety of NPP development in the world. In particular, passive safety systems began to assist the reactor cooling system when the active system failed. However, it has a lower active cooling system to effectiveness compared. The passive cooling systems can be relied upon to assist cooling that they do not require a power source to drive the work system and can work naturally in circulation. The safety system technology is a passive safety system, also developed by National Nuclear Energy Agency (BATAN). It cools and dissipates heat passively for nuclear heat pipe technology. The Loop Heat Pipe (LHP) type dissipates heat passively. Therefore, it is necessary to carry out the clearance function to determine whether a nuclear technology is feasible or not to be widely used and commercially valid. This study intended to measure the level of technology readiness to avoid technological failures through technology audits. This research method used is measuring Technology Readiness Level (TRL) and ensuring that the LHP nuclear technology used has met mature requirements and meets quality standard requirements. The results of the LHP technology audit with TRL measurements show TRL 4 of Data Acquisition System (DAS), LHP Design Program, System Integration sub-systems. The cause of problems about the preparation of hardware production not implemented, market research and laboratory research to select the fabrication process and the production process not been reviewed by the manufacturing department. Therefore, it is necessary to implement of prepare hardware production, market research, and laboratory research. Also, the manufacturing department review the fabrication and production process to increase the measurement of TRL [ABSTRACT FROM AUTHOR]
