Division Spotlight
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

NRC restores expiration dates for renewed Turkey Point licenses
The Nuclear Regulatory Commission announced this week that it has restored the expiration dates of the Turkey Point nuclear power plant's units 3 and 4 subsequent license renewals (SLR) to July 19, 2052, and April 10, 2053, respectively.

The effect of long-term oxidation on the total hemispherical emissivity of Type 316L stainless steel (SS 316L) is of interest in nuclear plant safety and is reported on here. ASTM standard C835-06 [American Society for Testing and Materials, 2006] was used for measuring the total hemispherical emissivity of this material for the following surface conditions: (1) “as-received” from the manufacturer (essentially unoxidized) and (2) oxidized in air at 573 K for up to 3000 h. The emissivity of the as-received samples varied within the range from 0.24 at 434 K to 0.34 at 1026 K. Oxidation in air at 573 K for 500 h increased the emissivity range of the oxidized sample from 0.28 at 429 K to 0.38 at 1096 K. There was no further significant change in emissivity observed following an increase in the oxidation time from 500 to 3000 h. It is suspected that the emissivity ceased to increase during the additional oxidation time because of chromium oxide that formed on the SS 316L surface inhibiting further oxidation.
