Management Review of Uncontrolled Change to Denitrator

Discussion of Results:

Record Review: The Intermediate Evaporator system was walked down against system drawings,

including hardware, piping, labeling, and design features. Parts of the Primary and Secondary Extraction

Systems and the Denitrator system were also walked down. There was excellent consistency between the

physical configuration and the facility documentation. Safety design features were generally noted on the

Process System Diagrams (PSDs). Component labeling was excellent. A small number of safety design

features that could use improved notation on the PSDs for configuration management purposes were noted.

Minor editorial differences between control panel labels and the PSD for the Denitrator were noted.
