Ensuring a role for nuclear in the response to climate change
Nuclear power is an important tool in the response to climate change, and advanced reactors may offer advantages over existing plants in providing carbon-free generation at the scale necessary to respond to the existential challenge that climate change presents. The International Atomic Energy Agency is aggressively addressing issues related to the possible transition to advanced reactors. This letter is to urge a redoubling of effort by Member States to put in place the necessary capabilities to deal with the challenges that they present.

Compton camera is a promising instrument for nuclear material imaging in arms control scenarios. In planning to build a Compton camera to detect the symmetry of shielded nuclear materials, the energy spectrum of gamma-rays escaping from the Steve Fetter Nuclear Warhead model is obtained using Monte Carlo simulation. Then, a point model is defined for our study. The proposed Compton camera uses a 5-cm × 5-cm × 1-mm double-sided silicon strips detector as the scattering detector and a segmented ϕ5.08 × 5.08-cm NaI(Tl) array as the absorbing detector. How high-energy gamma-rays impact low-energy characteristic gamma-ray imaging is studied. The result shows that high-energy gamma-rays will reduce the imaging accuracy and signal-to-noise ratio. The holistic angle resolution measured can reach 4.15 deg by all characteristic gamma-rays. The symmetry research result shows that the Compton camera can detect the symmetry property of a nuclear warhead with obvious symmetry or asymmetry.
