J. Buongiorno / Spring 2005 22.313J, 2.59J, 10.536J THERMAL-HYDRAULICS IN POWER TECHNOLOGY Homework Set 6 1. Calculation of the MDNBR in the PWR Hot Channel Consider the PWR hot channel geometry and operating conditions from Homework Set 5. i) Find the distribution of the DNBR in the channel. ( Hint: use the Tong-68 correlation, and ignore grid spacer effects) ii) What is the location of the MDNBR? iii) If the inlet temperature is decreased, while all other operating conditions are kept constant, how does the DNBR distribution in the channel change? Provide a qualitative sketch of the new distribution. 2. Thermal Analysis of the BWR Fuel Assembly A typical 8 × 8 BWR Fuel Assembly (FA) is shown in Figure 1. Only 62 (out of 64) positions are occupied by fuel pins, the other two positions are occupied by so-called “water rods”, which generate no heat. The heated length of the fuel pins is 3.81 m. The FA operating conditions are as follows: Pressure: 6.4 MPa Inlet temperature: 270 ° C (corresponding to an inlet enthalpy of 1183.8 kJ/kg)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
