Protons are positively charged, electrons are negatively charged, while neutrons are electrically neutral. ( )2. In many nuclear reactions there is an interchange of mass and energy. ( )3. Low energy neutrons usually interact with nucleus more difficult than high energy neutrons. ( )4. There are three types of interaction between gamma rays and the matter: photoelectric scattering, photoelectric effect, and electron-positron pair production. ( )5. During normal operation, the Zircaloy fuel cladding material can react with water to produce hydrogen gas. ( )6. Except water and heavy water, carbon dioxide and inert helium gas are regarded as two most suitable gaseous coolants for gas-cooled reactors, and liquid sodium as the standard coolant for fast breeder reactors. ( )7. If the multiplication factor is less than one the reactor is supercritical. ( )8. The time of the operating fuel cycle is about several years. ( )9. During operation the highest temperature in the reactor is in the center of fuel rod. ( )10. When the CEA is inserted, the reactivity is withdrawn. ( )11. Within the reactor vessel the core barrel is a support structure. ( )12. The fission threshold detectors monitor the neutron flux. ( )13. The fuel assemblies are put on the lower support structure. ( )14. The core support barrel assembly is supported by its lower end. ( )15. The fuel assemblies used in a reactor are same. ( )16. The fuel rod provides three barriers to the escape of fission products. ( )17. The reactor coolant should be chemically non-reactive with other components of the reactor. ( )18. For safety and control consideration, the reactor is usually designed to have a positive reactivity coefficient. ( )19. The RCS must be depressurized before injection can occur. ( )20. The long-term control of core reactivity means adjustment of boric acid. ( )Part Three: Singe choice (20 points, 1point each)1.
