Containment Shell or Liner Moisture Barrier Inspection

AGENCY: Nuclear Regulatory Commission.

ACTION: Regulatory issue summary; issuance.


SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing 
Regulatory Issue Summary (RIS) 2016-07, ``Containment Shell or Liner 
Moisture Barrier Inspection.'' This RIS reiterates the NRC staff's 
position regarding American Society of Mechanical Engineers (ASME) code 
inservice inspection requirements for moisture barriers. The NRC's 
regulations require, in part, that licensees implement the inservice 
inspection program for pressure retaining components and their integral 
attachments of metal containments and metallic liners of concrete 
containments in accordance with the ASME Code. If a material prevents 
moisture from contacting inaccessible areas of the containment shell or 
liner, especially if the material is being relied upon in lieu of 
augmented examinations of a susceptible location, the material must be 
inspected as a moisture barrier. The applicable ASME Code sections 
require licensees to inspect 100 percent of accessible moisture 
barriers during each inspection period.

DATES: The RIS is available as of May 23, 2016.
