' INSERT - B TECHNICAL SPECIFICATION PAGE B 3/4J.-5 3
The specification allows use of substituted TIP data from symmetric channels if the control rod pattern is symmetric since the TIP ' data is adjusted by the plant computer to remove machine dependent and power level e
dependent bias. The source of data for the substitution may also be a
)
's-dimensional BWR core simulator calculated data set which is normalized to available real data. Since uncertainty could be introduced by the simulation and normalization process, an evaluation of the specific control i
rod pattern and core operating state must be performed to ensure that adequate margin to core operating limits is maintained.
