As an example of research activities in decontamination for decommissioning, new data are presented on the options for corrosion layer dissolution during the decommissioning decontamination, or persulfate regeneration for decontamination solutions re-use. For the management of spent decontamination solutions, new method based on solvent extraction of radionuclides into ionic liquid followed by electrodeposition of the radionuclides has been developed. Fields of applications of composite inorganic-organic absorbers or solid extractants with polyacrylonitrile (PAN) binding matrix for the treatment of liquid radioactive waste are reviewed; a method for americium separation from the boric acid containing NPP evaporator concentrates based on the TODGA-PAN material is discussed in more detail. Performance of a model of radionuclide transport, developed and implemented within the GoldSim programming environment, for the safety studies of the LLW/ILW repository is demonstrated on the specific case of the Richard repository (Czech Republic). Continuation and even broadening of these activities are expected in connection with the approaching end of the lifespan of the first blocks of the Czech NPPs.

The causes of juvenile crimes are varying with many reasons, can not be just defined with one reason. It is very easy for juveniles to become violent and fall into misdeed, bad social environment; such as, family or parents' divorce problems accelerates this kind of misbehavior, especially when they are mentally acuity in this stage of their lives. On the impulse of the moment directly connects to the delinquencies which make their life miserable and furthermore, they become an obstruction of the society and country. Juvenile delinquents have to be take cared with psychological treatments, such as using a dog, because their hearts are dried up for many reasons. It is possible to help delinquents in The Chun An Juvenile Prison to reduce criminal minds and violent behaviors through psychological treatments and reform edification to make them love animals. This study has been researched through result of surveysand MMPI tests on guard diaries and observation record for using dogs as a treatment for violent reduce of juvenile delinquents in The Chun An Juvenile Prison. With the result, we came to the conclusion that it will be a suitable program for juvenile and female delinquents in the future.
