Computer Data Processing to Compute Nerva Transfer Functions

For complex systems and for systems where only a limited number of tests can be conducted, computers are needed to simulate the system for performing design and malfunction studies. These tests are conducted to, first, verify the validity of the simulation and, second, to upgrade the analytical program when test data become available. In the NERVA system, one of the methods for evaluating the analytical description and computer simulation is through the application of transfer functions. This paper will describe the computer data-processing methods that have been developed to permit total data analysis completion within a 72-hr period. To achieve this goal, it was necessary to establish efficient and flexible programming methods and to ensure that the data are valid when the tests are conducted. Because interpretation is essential, a well planned systematic approach to verification and simulation was introduced early in the program to study and interpret anomalies that could occur in the data.
