Davis-Besse Nuclear Power Station Annual Assessment Meeting Open House June 11, 2015 2014 Reactor Oversight Process Nuclear Regulatory Commission - Region III

Our Mission The NRC Regulates To license and regulate the

  • Nuclear reactors commercial power reactors, research and test reactors, new reactor designs nations civilian use of byproduct, source, and
  • Nuclear materials nuclear reactor fuel, radioactive materials special nuclear materials to for medical, industrial, and academic use ensure adequate protection of public health and safety,
  • Nuclear waste - transportation, storage and disposal of promote the common nuclear material and waste, decommissioning of nuclear defense and security, and facilities protect the environment.
  • Nuclear security - physical security of nuclear facilities and materials from sabotage or attacks 2 3 What We Dont Do Some Nuclear Facts
  • Regulate nuclear weapons, military reactors,
  • 99 nuclear power plants supply or space vehicle reactors about 20 percent of the electricity in the U.S.
  • Nuclear materials are used in
  • Own or operate nuclear power plants medicine for diagnosis and cancer treatment.
  • Nuclear materials are widely used in
  • Regulate some radioactive materials, such as industry, such as in density gauges, flow measurement devices, Xrays and naturally occurring radon radiography devices, and irradiators.

DavisBesse Shield Building (SB) Actions in Response to the Japan Nuclear Accident In 2013, indications of crack growth were identified

  • Actions in response to Japan Nuclear by licensee during scheduled bore hole examinations Accident: http://www.nrc.gov/japan/japan Possibility of continued crack growth is being info.html addressed by licensees SB longterm monitoring program
  • Mailbox for comments on staff actions:

Reestablishment of SB licensing basis to accept JLD_Public.Resource@nrc.gov laminar cracking will require a license amendment

  • Office of Public Affairs Point of
