The meteorological monitoring system (MIDAS)is not available in the Unit 1 Control Room hence the abilityto anticipate tornado winds is diminished. Per administrative controls associated with design deficiencies on diesel air intake and exhaust structures the diesels must be declared inoperable and fuel movement suspended.
