CONCEPTUAL DESIGN AND EVALUATION STUDY OF 10,000-kwE AQUEOUS HOMOGENEOUS NUCLEAR POWER PLANT

In this paper a new technique to handle solid radioactive materials inside a liquid matrix is presented. The conceptual design of the device profits of the experience and know-how gained in decontamination procedures. The proposed system makes use of an ejector for the suction of a water-highly radioactive swarf mixture from the purifiers pool of the Italian E. Fermi NPP and moving it in a suitable container for the subsequent conditioning. A dedicated circuit with an ejector to demonstrate the feasibility of the method was realized. A minimum inlet flow was found to have swarf suction. No swarf packaging conditions were observed in the performed tests, demonstrating the feasibility of the method.

The Impact

CP1000, improved from 2nd generation nuclear power plant technology, is a new concept of 2nd plus technology, some improvements of which are relatively mature. Based on the technology of 2nd plus, two new design improvements are being implemented, substituting high pressure safety injection with middle pressure safety injection and adding a function of fast cooling when an accident happens. Using code RELAP5, this article calculated and analyzed SGTR accident in order to evaluate the impact of the two improvements.

A New Technique

In this paper, a new technique to handle solid radioactive materials inside a liquid matrix is presented. The conceptual design of the device profits of the experience and know-how gained in decontamination procedures. The proposed system makes use of an ejector for the suction of a water-highly radioactive swarf mixture from the purifier pool of the Italian E. Fermi nuclear power plant (NPP) and moving it in a suitable container for the subsequent conditioning. A dedicated circuit with an ejector to demonstrate the feasibility of the method was realized. A minimum inlet flow rate was found to have swarf suction. The feasibility of the method was demonstrated, even if it is required to homogenize the inlet mixture to avoid swarf packing conditions inside the ejector.
