摘要:
In order to implement the integration management of the occupational health and safety and environment (OHSE) in an operating nuclear power plant (ONPP) in East China and help it pass the OHSAS 18001 and ISO 14001 certifications simultaneously rather than separately, an integrated management system (IMS) for OHSE in the ONPP consisting of the occupational health and safety and environment management manual (OHSEMM) and its supportive documents was established to cover the OHSAS 18001 and ISO 14001 standards and IAEA's safety standards on management systems. The management information system for the IMS for the ONPP in East China (MISIMSONPPEC) consisting of the core zone, which includes the information-sharing platform (ISP) and the functional management system (FMS), client and background system was designed for the first time by using browser/server (B/S) structure to overcome the difficulties in implementing the IMS. The applications of the MISIMSONPPEC in the ONPP show that it helped to share and statistically analyze the OHSE data and information from the IMS, to improve the cooperation between departments, to enhance the efficiency of management, and to pass the OHSAS 18001 and ISO 14001 certifications simultaneously rather than separately; and it helped accomplish the integration management of the OHSE in the ONPP.
摘要:
It is the fact that there are lots of hazard incidents in underground uranium mines caused by radon but in-suit uranium samples were difficult to collect. Based on closed chamber method, three similar samples in different sealed ways were made in a laboratory with different material rations, namely uranium tailings, quartz sand, cement, iron powder and silicon powder to measure the radon concentrations with and without low-frequency vibrations, which was used by the experimental device for low-frequency vibration diffusion of radon. The results showed that the radon exhalation coming from the similar samples was influenced by the low frequency vibration; the results are presented as two-stage variations compared with the blank group. The radon exhalation increased with the rising vibration frequency when the frequency was 50 to 70 Hz, but fell slowly after reaching the peak radon exhalation rate. Analyses of the relations between the rock damage degree, changes in porosity and the occurrence of an inflection point in the radon exhalation rate in the samples found that they also increased when the frequency was between 0 to 80 in sample 3. The maximum porosity of the third samples was about 4.8% with a low-frequency vibration 60 Hz, while the maximum damage degree was about 0.07 at 50 Hz.

摘要:
Cyanobacteria are freshwater microorganisms that can bloom and produce toxins that contaminate water. There is thus a need for methods to remove cyanobacteria, by flocculation for instance. Here, we prepared new flocculants by modifying waterwork sewage sludge. Flocculant (A) or (B) were prepared by treating 3 g of preprocessed sludge in hydrochloric acid and heating at 200 or 250 A degrees C for 3.0 h. Flocculant (A) and (B) were used to remove Microcystis aeruginosa colonies by adding 0.75 mL of flocculant to 100 mL of algal culture and incubating for 8 h. Results show removal efficiencies of 72 and 91%, respectively. Total nitrogen was reduced by 30 and 12%. Total phosphorus was reduced by 75 and 76%. Chlorophyll fluorescence showed that cyanobacterial cells were removed without damaging the membrane integrity. Overall, findings show that modified waterworks sludge flocculants have good potential for the control of algal blooms, the removal of total nitrogen and total phosphorus and the restoration of aquatic ecosystems.
