Instrument air dew point requirements -- 108-P, L, K

摘要

The 108 Building dew point analyzers measure dew point at atmospheric pressure. Existing 108 Roundsheets state the maximum dew point temperature shall be less than (minus)50 F. After repeatedly failing to maintain a (minus)50 F dew point temperature Reactor Engineering researched the basis for the existing limit. This report documents the results of the study and provides technical justification for a new maximum dew point temperature of (minus)35 F at atmospheric pressure as read by the 108 building dew point analyzers.
