"White" data Is an Indication of potentially unreliable data. It may be normal and acceptable due to low or no flow In the effluent vent or may Indicate a release exceeding the range of the Instrument or-an instrumentation/
computer interface problem.
NOTE:
White data should be considered as a potential unmonitored release condition unless Engineering or Chemistry data Indicates otherwise.

- 3)
Valid In the field radiological measurements or
- 4)
In the absence of valid measured radiological data, a MIDAS Default or NUREG-1228 calculation based on inputs that are judged by Engineering to be consistent with the current conditions In the affected unit.
NOTE:
Study Case Calculations are hypothetical calculations that are based on assumed, unverified plant conditions and leakage rates and meteorology that existed at the time of the calculation.
(3)
In the absence of valid measured radiological data, perform a Valid MIDAS Default Accident or NUREG 1228 Calculation. Use results for EAL Classification and PAR determinations only when:
