Enforcement Letter issued to Geiger Brothers Mechanical Contractors, Inc. related to Installation and Inspection of Penetration Fire Seals at the DUF6 Conversion Building at the Portsmouth Gaseous Diffusion Plant
This letter refers to the Office of Health, Safety and Security's Office of Enforcement investigation into the facts and circumstances associated with deficiencies in the installation and inspection of penetration fire seals at the DUF6 Conversion Building, located at the Portsmouth Gaseous Diffusion Plant. DOE's investigation report, dated January 22, 2009, was provided to Geiger Brothers Mechanical Contractors, Inc. (Geiger) under separate cover.
Potential violations of 10 C.F.R. § 820.11, Information Requirements, and 10 C.F.R. Part 830, Nuclear Safety Management, occurred in association with this event, including: seals that were not installed in accordance with the approved assembly drawing; seals that were installed without an approved assembly drawing; and completed documentation (fire seal travelers) that indicated inspection and acceptance of the installed fire seals by Geiger's quality control inspector, when in fact the installations were never performed. Among the potential violations reviewed were Geiger's failure to detect and correct quality problems with inspections, documentation, and nonconformance’s; the failure to comply with approved procedures; the use of inadequate procedures to effectively control the intended activity; and the failure to ensure that inspection and testing adhered to established requirements.
