The goal of the project.

The following list is a somewhat rigorous explanation to what is wanted from this simulation.

• The goal is to simulate the gamma radiation flux outside a nuclear fuel assembly inside a steel box. The flux distribution is to be calculated in 8 points per mm³ for 10 distances from the steel box with 200x10³ gamma rays per point for 3 different gamma ray source density distributions.
• The product of all these numbers is the total number of gamma rays that is given in the table with results.
• Further, this goal is to be achieved for 21 different gamma ray energies and 4 different water temperatures. Fortunately, the energy and temperature variation is simulated simultaneously for each traced gamma ray.

Now, the above list is an explanation of the ULTIMATE GOAL for this example. There is also a PRIMARY GOAL for this project. This goal is the flux simulated at only one radial distance from the box, for only one source distribution and for only half as much statistics as for the ultimate goal. Reaching the primary goal does not mean that the distributed effort will stop when it is reached, on the contrary, it will continue.

The effort of DCypher.Net is contributing to these goals in the following way:

1. The PRIMARY GOAL is what is being reached for in the 1^st version of the DCypher.Net clients. The clients further calculates the gamma flux with very good statistics, 4.5 million gamma rays per point. As you may have seen on the DCypher.Net site, this goal have been reached! Calculated data have been shipped from Dcypher.Net to me for analysis.
2. The ULTIMATE GOAL is what will be reached for in the 2^nd version of DCypher.Net clients. This version will go on and calculate the gamma flux in 10 distances from the steel box
