History of uranium exploration and the general situation of identified uranium resources in China are introduced briefly in the paper, the feature of uranium resources is summarized as “big number of deposits, good ore processing properties and centralized occurrence”,which should be considered as the advantages. In accordance with the fact that the exploration level of uranium resources is quite low in China, it is pointed out that exploration investment must be intensified from now on to identify more uranium concentrated base which occurring of middle-large size uranium deposit in order to meet the demand of natural uranium from nuclear power sector. Besides, main scientific and technological achievements on uranium exploration during the past fifty years are elaborated in the paper. According to the exploration ability and uranium resources potential in China, it is believed that uranium exploration can realize the goal of “getting break through both in home and abroad” and guarantee to meet the requirement of nuclear industry to uranium resources in China by carrying out the uranium resources exploration strategy of “rooting domestic and open up abroad”.

Electrolytic manganese (EMM) industry with a large amount of waste water and high density of pollution, belonging to the high polluting industries, is one of the main threats of pollution control and emission reduction. Based on the analysis of the pollution prevention status of EMM industry, index system for pollution prevention technological evaluation was built. This paper obtained weight and quantifying value of each index with analytic hierarchy process (AHP), and evaluated the technology of pollution prevention using comprehensive index. On this basis, prediction of pollution reduction potential of best available technologies (BATs) was made using bottom-up model. The result showed the total emissions of waste water would be reduced more than 2.7×106 t, the reduction of ammonia nitrogen emission could be 6.6×104 t, recovered manganese and potassium bichromate could be 1.9×105 t and 3.747×107 t respectively, the reduction of manganese slag emission could be 4×106 t in 2015, comparing to the baseline year 2010. It also proved that clean production technology was superior to end treatment, and clean production technology would be widely used.
