Specify in Abstract below or in LICENSEE EVENT REPORT (LER)

CONTINUATION SHEET Edit Typical Sleeve and Anchor Bolt Details on design drawings to add a note to specify the anchor type. Due June 28, 2013.

Add the lessons learned from this event to the initial class for Print Reading for Engineers. Due April 15, 2013.

Cover details of this event as the Lessons Learned in Engineering Continuing Training. Due June 28, 2013.

Revise Design Engineering procedures to validate assumptions in calculations, engineering analysis, and configuration control procedures to review all available references. Due March 29, 2013.

Additionally, a Fundamental Performance Deficiency in engineering design and configuration control processes has been identified in Condition Report 2012-08125. Corrective actions from that condition report, which are applicable to this condition, are:

The development of a "Conduct of Engineering - Principles and Expectations" procedure, Update/revise various engineering procedures based on a gap analysis of PED-HU-1, "Engineering Human Performance Program", and Develop and issue Engineering review guidance for Vendor/Contractor design changes to ensure thorough and rigorous reviews by design engineering.

SAFETY SIGNIFICANCE

The results of the calculation completed on January 9, 2013, shows that during a seismic or barge impact event the raw water pump anchor bolts would remain functional. Therefore, there would be no loss of a safety function and no impact to safety.

SAFETY SYSTEM FUNCTIONAL FAILURE This event does not result in a safety system functional failure in accordance with Nuclear Energy institute, NEI-99-02.

PREVIOUS EVENTS No previous LERs concerning inadequate embedment of safety related anchors have been noted.
