89 Study I: Sensitivity Analysis with CPs 1. Select one power and one desalination option (one case) 2. Vary one parameter at a time, in steps of+/- 0, 2, 5, 10, 20 % Parameters: desalination capacity power plant investment TDS cost seawater temperature interest rate 3. Yield 9 Cases - 1 Comparative Presentation (CP) each 4. Print the CPs 5. Put the results in a small report Idea sheet: Description of the task Analysis of the findings Graphs with explanations May 2001 NPTDS, Department of Nuclear Energy International Atomic Energy Agency, Vienna, Austria Study 5

90 Study II: Capacity Effect in Distillation 1. Select one nuclear option and either MED or RO (plus, if time allows, one fossil option) 2. Vary the desalination capacity, save each case start with loooomvd end with m 3 /d start with small steps, increase step size 3. Create an Excel graph for water cost vs. capacity 4. Put the results in a small report Idea sheet: Description of the task Analysis of the findings Graphs with explanations May 2001 NPTDS, Department of Nuclear Energy International Atomic Energy Agency, Vienna, Austria Study 6

91 Study III: Using the Simple Solver ^ 1. Select one fossil option and either MED or RO 2. For desalination fix various numbers for the desalination base unit cost determine the O&M cost for desalination needed to keep the water cost at l$/m 3 using the Simple Solver 3. For power fix various numbers for the fossil fuel price determine the base construction cost for the power plant needed to keep the water cost at l$/m 3 using the Simple Solver 4. Put the results in a small report Idea sheet: Description of the task Analysis of the findings Graphs with explanations May 2001 NPTDS, Department of Nuclear Energy International Atomic Energy Agency, Vienna, Austria Study 7

92 Study IV: Hybrid Cases using the Solver f ^ For hybrid plants, all steam available is used for MED. Then, DEEP adds RO capacity to reach desired total water capacity. 1. Select one nuclear power option and MED/RO 2. Fix the water plant capacity, e.g. to m 3 /d 3. Vary the maximum brine temperature (Tmb) 4. (This affects the total heat going to the MED plant with fixed steam flux.) Document the changes in the MED/RO capacity distribution. Use the Simple Solver to achieve the desired MED/RO capacity by adjusting Tmb. 5.
