There is not a common attitude in a society for socio-scientific issues (SSI) such as whether to use nuclear power plants for energy production. Within this respect, the aim of the research is to examine pre-service science teachers’ and pre-service social studies teachers’ attitudes toward SSI and to reveal their views about setting up nuclear power plants in their country. The participant of research is 120 pre-service teachers. Firstly, Attitudes toward Socio-scientific Issues Scale (ATSIS) was implemented and then, focus group discussions were done with five students from each department separately so as to understand their views about nuclear power plants. Findings revealed that whereas pre-service teachers are eager to learn more about SSI, they have anxiety about it due to religion, moral and ethical perspectives. In addition, whereas both groups of pre-service teachers have some common views about nuclear power plants, pre-service science teachers do not have more positive views about having nuclear power plants in their country. Key words: attitude towards socio-scientific issues, focus group discussion, pre-service teachers, nuclear energy.

In thermal and nuclear power plants, 70% of the generated thermal energy is lost as waste heat. The temperature of the waste heat is below the boiling temperature of water. Here, we show a long-term heat-storage material that absorbs heat energy at warm temperatures from 38°C (311 K) to 67°C (340 K). This unique series of material is composed of scandium-substituted lambda-trititanium-pentoxide (λ-ScxTi3−xO5). λ-ScxTi3−xO5 not only accumulates heat energy from hot water but also could release the accumulated heat energy by the application of pressure. λ-ScxTi3−xO5 has the potential to accumulate heat energy of hot water generated in thermal and nuclear power plants and to recycle the accumulated heat energy on demand by applying external pressure. Furthermore, it may be used to recycle waste heat in industrial factories and automobiles.
