Attachment 1 - Drawing 3.pdf

This file appears to be a detailed piping and instrumentation diagram (P&ID) marked "FOR OFFICIAL USE ONLY" showing reactor utility valve systems and pressure/flow controls. The drawing includes multiple stations with pressure gauges, flow indicators, quick connect fittings, and various valve configurations connected through an intricate network of piping. The diagram features components such as hot waste sample stations, process room connections, reactor utility valve supply systems, and flow regulators/separators, all annotated with standard P&ID symbols explained in the legend on the right side of the drawing.

The technical detail and restricted marking suggest this is a sensitive engineering document related to the NIST reactor recovery services contract. The drawing provides essential information about the reactor's utility systems that would be relevant for contractors bidding on the reactor recovery services work outlined in solicitation 1333ND25RNB610012. The complexity and scope of the systems shown indicate this is a significant technical facility requiring specialized nuclear engineering expertise.
