IAEA promoting nuclear energy with G20
The International Atomic Energy Agency launched a collaboration with the Group of 20 this week to highlight the key role that nuclear energy can play in achieving energy security and climate-change goals.
The aim of this first-of-its-kind partnership with G20—the world’s largest economic group—is to build momentum for nuclear power. This is the first time the IAEA has presented to G20 on issues relating to nuclear power.

A simple core control code is developed for the control of a nuclear reactor in the load following operation. The core state equations are described by the one-group diffusion equation with moderator temperature and xenon feedbacks and iodine-xenon dynamics equations. The control via control rod, boron, and coolant inlet temperature is considered. To avoid the conventional difficulties of a two-point boundary value problem, the optimal control problem is solved by the direct numerical technique of the mathematical programming without the separation of space and time variables. This quadratic programming problem is solved by the Davidon-Fletcher-Powell method, which is a general unconstrained optimization method. In the cases of the load following operation of Korea Nuclear Units 7 and 8, the results obtained by using the present model show that the scheduled load demand is successfully followed, and the power distribution maintains the desired distribution with a minimum amount of control action.
