碩士 === 國立臺北科技大學 === 工業工程與管理研究所 === 97 === The RPV(Reactor Pressure Vessel) water level is one of the most critical monitoring parameters in nuclear plant operation, however, the two RPV water level displays in the Lungmen Nuclear Power Plant: Wide Display Panel (WDP) and Video Display Unit (VDU) SDPS C92、C93 displays both are unable to effectively provide operators the RPV water level information; it may also cause the misread of the water level. Therefore, a new RPV water level displays which can assist operators to effectively monitor the water level is essential. In the concerns of feasibility and contribution, this research aim to redesign the VDU SDPS C92、C93 displays on the prerequisite of maintaining the data content. In addition, based on an interface display design theory of EID (Ecological Interface Design), this research combines document research and interview approach in order to elicit the operators’ actual needs of the RPV water level information. The newly designed RPV water level display was evaluated by 17 operators in the Lungmen Nuclear Power Plant by two kinds of questionnaires. Use revised SA (SWORD) questionnaire to evaluate workloads and situation awareness and revised SUS questionnaires to evaluate usability. The research has shown that new RPV water level displays are able to reduce human errors, enhance operator’s performance of and further improve the safety of nuclear plant.
