Dear jedishrfu, Thanks for your help. I done success. :)

Dear all, I want to read file "d1.dat": 1.025000+7 5.794453+0 1.050000+7 5.770080+0 1.075000+7 5.750135+0 1.100000+7 5.734860+0 1.125000+7 5.724448+0 1.150000+7 5.719060+0 1.175000+7 5.718829+0 1.200000+7 5.723865+0 1.219440+7 5.730802+0 1.225000+7 5.732945+0 1.250000+7 5.743325+0...

Thanks PF Patron! That's nice solution. I have one more question about format: do you know how to remove letter 'E' in result (This looks like 1.000000-5 replace 1.000000E-5).

I'm trying to read the next data text file :cross.dat 1.000000-5 0.000000+0 2.530000-2 0.000000+0 7.712958+1 0.000000+0 2.250000+3 0.000000+0 2.250000+3 1.838880+1 2.300000+3 1.936710+1 2.500000+3 1.986000+1 2.650000+3 1.843220+1 2.900000+3 1.832230+1 3.000000+3 1.816280+1...

"Nuclear Systems I - Thermal Hydraulic Fundamentals" - Todreas

Thank QuantumPion comments! I think it is one of the problems of a nuclear engineer working with thermodynamics. My problem is "Compute the ratio ,of the primary to secondary fow rates" with pump of the primary. How change the cycle thermal efciency and the nuclear plant thermodynamic efciency...

Can you help me solution: The PWR plant of Figure 6-6 operates under the conditions given in Table 6-6. Assume that the turbine and pump have isentropic effciencies of 85%. 1. Draw the temperature-entropy (T-s) diagram for this cycle . 2. Compute the ratio ,of the...

Thank for help friends. I had solved this problem, because I can't type formula in forum so I can't post solution. If you need it, you could send me a PM.

This is Problem 3-5: Effect of continuous refueling on decay heat (section VIII) into pages 72 - book: Nuclear Systems I - Thermal Hydraulic FundamentalsAnswers in book: Case 1 / Case 2 1 minute: P = 81.9 MW / P = 81.0 MW...

Estimate the decay heat rate in a 300 MWth reactor in which 3.2% mU-enriched U02 assemblies are being fed into the core. The burned-up fuel stays in the core for 3 years before being replaced. Consider two cases: 1. The core is replaced in two batches every 18 months. 2. The fuel...

Thank for Astronuc about hint. I have solved the exercise.:smile:

I'm studying about Thermal Hydraulic. When i read book :"NUCLEAR SYSTEMS I Thermal Hydraulic Fundamentals" - Neil E. Todreas and Mujid S. Kazimi. I don't understand about : calculate "Minimum critical power ratio" & calculate "Pumping power" in problem: a) Calculate the minimum critical...
