| Title | Shipping Requirements Not in Accordance with Industry Standards |
| Description | The team identified an unresolved item associated with Unit 3 steam generators not shipped in accordance with specification SO23-617-01, Design and Fabrication of Replacement Steam Generators for Unit 2 and Unit 3, Revision 4, and requirements for handling, storage, and shipping. Specifically, ANSI N45.2-1977, Quality Assurance Program Requirements for Nuclear Facilities, required a special protective environment for handling, storage, and shipping of the replacement steam generators. However, because of schedule changes, the Unit 3 protective environment which included maintaining a nitrogen pressure and a monitoring plan was altered significantly. The team evaluated specifications associated with the shipping and handling of the Unit 2 and 3 replacement steam generators. Based on the information evaluated by the team, the steam generators procurement and shipping specifications required monitoring and maintenance of nitrogen atmosphere inside the replacement steam generators during shipment. Supplier Deviation Request SDR 10041870-09091 dated December 1, 2009, documents a request not to control the positive pressure, the dew point of nitrogen, and the oxygen content on the primary and secondary side of the Unit 3 replacement steam generators to accelerate delivery schedule. Specification SO23-617-01, Section 3.16.3, specifies the supplier shall be responsible for monitoring and maintaining nitrogen atmosphere inside the steam generators during their shipping from Mitsubishi to the California port discharge point. The team noted that Unit 3 steam generators did not require, monitoring or control of dew point, oxygen concentration, inside nitrogen pressure. The team could not identify if this was properly evaluated (Reference Section 5 of shipping and handling procedure SO23-617-1-M1350). Additional review and follow up will be required to review the evaluations and corrective actions associated with the maintaining the Unit 3 replacement steam generators protective environment during shipping and then determine whether this issue represents a performance deficiency or constitutes a violation of NRC requirements. |
