At a NATO-sponsored workshop in Almaty in September 2005, specialists from the IAEA, Brazil, France, Kazakhstan, Poland, Russia, USA and Uzbekistan discussed safety-related issues of storing spent nuclear fuel. Fifteen papers dealt with aluminium-clad fuel discharged from research reactors worldwide, five papers were concerned with stainless steel-clad fuel from fast reactors, and two were devoted to Zircaloy-clad fuel from commercial light-water reactors.

Although most attention was focused on fuel behaviour in storage pools, many countriesthrough lack of spaceare beginning to 'dry store' spent fuel in an inert atmosphere in shielded casks, and both topics were covered thoroughly at the workshop. Water quality and dryness of the spent fuel, respectively, are the critical factors in avoiding material degradation for the two storage modes. No burning safety-related issue emerged from the twenty-two papers presented; however, the lack of wet storage space at most reactors and concerns regarding possible sabotage remain as issues that need to be periodically addressed.

Broad coverage of topic: diverse reactor types and many countries represented at the workshop Cross-cut mixture of presentations of basic and applied research into spent fuel storage Wide and unique compilation of references to related work quoted in the 22 papers
