CuI is a candidate wasteform for the immobilization of the fission product ¹²⁹I. CuI can be made simply by the addition of CuCl to an I⁻ bearing solution such that exchange of Cl⁻ with I⁻ takes place. The CuI material can then be consolidated into a wasteform by sintering at approximately 550 °C in argon or by hot isostatically pressing at 550 °C with 100 MPa of pressure. A waste loading of greater than 60 wt.% is achievable with good water leach resistance, in keeping with the low solubility product of CuI. However, like the well known wasteform candidate AgI, CuI decomposes in water containing metallic Fe. To compensate this deficiency, the sintered CuI wasteform can be further protected by surrounding it by Sn powder and HIPing at the low temperature of 200 °C.

的CuI对于裂变产物的固定化的候选wasteform ¹²⁹ I.的CuI可以简单地通过添加的CuCl到I进行^-轴承溶液中，使得氯的交换^-与I ^-发生。然后，可通过在大约550°C的氩气中烧结或在550°C的压力下以100 MPa的压力进行热等静压，将CuI材料固结为废料。在保持良好的耐水浸出性的同时，与CuI的低溶解度产物保持一致，可以实现大于60重量％的废物负载。但是，CuI像众所周知的废料候选AgI一样，会在含有金属Fe的水中分解。为了弥补这一不足，可以通过在锡粉周围包裹烧结的CuI废料并在200°C的低温下进行HIP处理来进一步保护它。
