Nuclear Reactor Theory, JU, Second Semester, 2008-2009 (Saed Dababneh). 2 Grading Review Test10% Mid-term Exam30% Projects, quizzes and HWs20% Final Exam40% Homeworks and small projects are due after one week unless otherwise announced. Remarks or questions marked in red without being announced as homeworks should be also seriously considered! Some tasks can (or should) be sent by email: saed@dababneh.com

3
Nuclear Reactor Theory, JU, Second Semester, 2008-2009 (Saed Dababneh). 3 Review Test Review relevant material. Read Lamarsh Chs 1, 2 and 3. Read Krane Ch. 13. Will do the test afterwards.

4
Nuclear Reactor Theory, JU, Second Semester, 2008-2009 (Saed Dababneh). 4 Projects Radiation protection and shielding (Due May 10 th ). Nuclear fuel cycles with emphasis on front ends (Due May 10 th ). Work as a team. Divide and organize the job among you. Try to explore local applicability. Presentation: Will be scheduled later. Other small projects will be announced in class.

5
Nuclear Reactor Theory, JU, Second Semester, 2008-2009 (Saed Dababneh). 5 Nuclear Reaction Energetics (revisited) Conservation Laws Charge, Baryon number, total energy, linear momentum, angular momentum, parity, (isospin??) ……. a papa X pYpY pbpb Y b +ve Q-value exoergic reaction. -ve Q-value endoergic reaction. +ve Q-value reaction possible if T a 0. -ve Q-value reaction not possible if T a 0. (Is T a > |Q| sufficient?). Conservation of momentum ……

6
Nuclear Reactor Theory, JU, Second Semester, 2008-2009 (Saed Dababneh). 6 Conservation of momentum. We usually do not detect Y. Show that: The threshold energy (for T a ): (the condition occurs for = 0º). +ve Q-value reaction possible if T a 0. -ve Q-value reaction possible if T a > T Th. Coulomb and other barriers…….!!! Neutrons vs. charged particles. HW 1 Nuclear Reaction Energetics (revisited)

7
Nuclear Reactor Theory, JU, Second Semester, 2008-2009 (Saed Dababneh). 7 Nuclear Reaction Energetics (revisited) The double valued situation occurs between T Th and the upper limit T a \. Double-valued in a forward cone. HW 1 (continued)

8
Nuclear Reactor Theory, JU, Second Semester, 2008-2009 (Saed Dababneh). 8 Discuss thoroughly the 7 Li(p,n) reaction. During the discussion emphasize on the case when the incident proton beam is 30 keV above the threshold. Use your computing skills. Nuclear Reaction Energetics (revisited) HW 1 (continued) elastic inelastic scattering neutrons Discuss the elastic and inelastic scattering of neutrons using these relations.
