predicted for maximum and minimum heat flux conditions with a steady-state code, including parameters to take into account some of the two-dimensional effects resulting from nonuniform circumferential solar heating. Thermal and stress oscillations occurring in the tube walls in the transition boiling region following the critical heat flux point are predicted for the maximum heat flux condition for the pilot plant and for the maximum and 80% of maximum heat flux conditions for the commercial plant. A two-dimensional rivulet model is used for the thermal analysis and a generalized plane strain elastic model is used for the stress analysis leading to fatigue life predictions. Dynamic stability is investigated with a frequency domain model, modified by adding a superheat regime. Nyquist plots are presented for the maximum and minimum heat flux conditions without and with tube inlet orificing. Water chemistry and potential deposition/corrosion effects are evaluated based on a review of modern boiler water practices and recommendations for the solar plant are presented. Show Less
