Learn how EGAT uses multimedia software to communicate site selection for nuclear power plants in Thailand. Follow the phases of the study with maps, criteria, and potential sites displayed through animations and evaluations, ensuring public understanding through visual aids. Witness the process of selecting the best candidate sites through a detailed presentation to the public, addressing safety concerns effectively while engaging with various stakeholders for feedback and assessment. Multimedia tools enhance public engagement and comprehension of complex technical information.

How to Present the Technical Messages to the Public
Site Selection for Nuclear Power Plant in Thailand
IntroductionSite Selection for Nuclear Power Plant in Thailand In1995 EGAT Identified five Candidate Sites, namely Ban Bang Berd, Ban Laem Tan, Ban Laem Yang, Ban Thong Ching and Ban Klong Muang.
Communicating technical messages to the general public has always been a great problem for EGAT
The multimedia software is consequently taken into consideration as a tool to present the Nuclear Power Plant Site Selection process.
How to Presentthe Technical Messages to the Public The Presentation follows the typical phased siting study that includes four Phases as shown in Fig.1 Fig.1
The Scenario ofPhase 1 The map of Thailand is used as the siting study areas (Fig.2). Exclusion and Avoidance criteria are shown in Fig.3. Fig.2 Fig.5 Fig.3
The Scenario ofPhase 1(continue) Upon applying the criteria to the Study Area, the map displays a gradation of areas where development should be excluded, avoided or preferred as shown in Fig.4. Selected Candidate Zones based on these results are shown in Fig.5. Fig.4 Fig.5
The Scenario ofPhase 2 The scene of First Step is shown in Fig.6. The map with Candidate Zones from Phase1 is located on the left hand side and in the center are the criteria to identify Potential Sites within the Candidate Zones. Animations show the Candidate Zones moving through the criteria with a number of red spots appearing in each yellow area of the Candidate Zones and running into the map in the right hand side. These red spots represent the Potential Sites as shown in Fig.7. Fig.6 Fig.7
The Scenario ofPhase 2(continue) The scene of Second Step is shown in Fig.8. In this step, 59 Potential Sites are screened through established criteria and conditions.14 sites are left over as a consequence. The map of Thailand with Candidate Zones and Potential Sites shown in red spots is located on the left hand side of the scene. In the center are two screens representing the criteria. The first screen allows sites to pass if theirs properties do not have any conflict with IAEA guidelines (Fig.9). Fig.8 Fig.9
The Scenario ofPhase 2(continue) The second screen disallows those sites whose score is lower than the established standard score (Fig.10). The public could easily understand how the sites are screened by the criteria and standards. Fig.10
The Scenario ofPhase 3 In this phase the scene of presentation shown in Fig.11 explains the assessment of engineering, environmental and economic aspects of Potential Sites. The combination of assessment also yields a multi-disciplinary ranking of the Potential Sites as shown by tables of evaluation matrix : engineering nuclear licensing consideration, environmental nuclear consideration and cost-related items consideration. Each table shows ranking score of all Potential Sites. Fig.11
The Scenario ofPhase 3 The summary of this phase is shown in Fig.12 and 13. In Fig.12 the scene shows two maps of Thailand with superposed triangles in the center representing. The factors of the assessment and the evaluation of ranking. The 14 Potential Sites passing into the triangles means that they are assessed and ranked. Five Candidate Sites come out as a result. The names and locations appear as shown in Fig.13. Fig.12 Fig.13
The Scenario of Phase 4 The scene of presentation (Fig. 14) shows the items of tables that include the comparison and evaluation of Candidate Sites while the flowchart of overall site ranking methodology is shown in Fig.15. The ‘best’ Candidate Sites are shown in Fig.16. Fig.15 Fig.16 Fig.14
Presentation to the Public The approved Nuclear Power Plant Site Selection software has been presented to groups of school teachers and some local newspaper columnists from target areas in the Southern part of Thailand as shown in Pic.17 and Pic.18. Questionnaires and face-to-face conversation are among the methods to evaluate the software. Pic.17 Pic.18
Conclusion The technical messages in the procedure of Site Selection for Nuclear power plant in Thailand could be effectively presented to the public by multimedia software. Explanation by pictures and animations instead of technical messages greatly help the audience understand much more easily. The question ‘Why did EGAT select our areas for nuclear power plant?” from the public in the target areas could well be answered by themselves.
Conclusion However ‘How can we be sure about the safety of Nuclear Power Plant?’ still poses a big question. Explanation of technical messages is and will still be a ‘natural’ problem for a long time to come as long as it is a complicated and difficult-to-understand scientific issue. How could we impress the public with the safety image in their mind?. Visits to a Nuclear Power Plant might be among the first options to be considered
