Title | LHSI/ORS Pump Discharge Piping Interference |
Description | A URI was identified by the inspectors relating to an issue involving interference between discharge piping for the Unit 1 A train LHSI pump and the Unit 1A train outside recirculation spray (ORS) pump. On August 4, 2009, the inspectors identified an interference issue involving hard contact between discharge piping for the Unit 1 A train LHSI pump and the Unit 1A train ORS pump. The licensee initiated CR343744 and performed an operability determination documented by OD000314 which concluded the as-found configuration was operable but not fully qualified and should be corrected during the next outage of sufficient duration. The licensees stress analysis package was forward to NRC regional and headquarters design personnel for additional review which has resulted in additional questions for the licensee. This issue is unresolved pending completion of NRC review of the licensees evaluation to determine if there is a performance deficiency which is greater than minor and is identified as URI 05000338/2009004-04, LSHI/ORS Pump Discharge Piping Interference. |
