Title	Inadequate Inspections on Thru-Wall Piping Penetration Sleeves
Event Description	The issue is associated with sleeved line penetrations thru walls [in the 300 Complex]. The documented periodic inspection was not adequate to verify the continued reliability and availability of the sleeve. In addition, the discussion in the supporting safety analysis was insufficient. During the two (2) year review of the safely-related equipment (SRE) test, it was determined that the test could not be performed as written and that the test did not verify the continued reliability and availability of the sleeve. In addition, after a review of the discussion in the supporting safety analysis, the discussion was determined to be insufficient. There were no actual safety consequences to workers, the public, or the environment. Although determined to be extremely remote because of the nature of the pipe and sleeve, the potential criticality consequences include a leak of uranium-bearing solution from the pipe and sleeve and into the wall. The safety significance is determined to be low due to the following: - the solution lines and sleeves are compatible with the associated uranium-bearing solutions (stainless steel); - the sections of lines and sleeves thru the walls are straight pipe with no connections; and, - leaks have not been observed in straight pipe and sleeve sections. Additional actions taken in response to the event: The number and locations of the sleeved line penetrations are being investigated. The grout/caulk may be removed to facilitate inspections of the sleeves. Safety-related equipment (SRE) tests and safety analyses are being revised to better describe the accident sequence/barriers and periodic inspections. The licensee notified the NRC Resident Inspector.
