Tritiated water can replace ordinary water in living cells (approximately 70 % of the soft tissue in the human body is water).
What is the source of waste water?
The main source of waste water discharged into the River Hron is industrial sewage water (cooling water) from Mochovce NPP, Units 1&2.
Industrial waste water can be classified as follows: waste water without radionuclides including cooling tower blowdown and water from regeneration of a system for demineralised water production; and waste water with low-active radionuclides, which originates by vapour condensation from radioactive liquid treatment.
For a good professional intervention in the event of hazardous waste release into the environment or health threat, it is necessary to have the basic and accurate information on waste [7,15].

So how to have the function of drawing contours of the software development, the seamless link to service application system, has become the hot spot of professional software development.
Surfer is the professional software by the Golden Software, the software has the XYZ coordinate system of automatic data into a data graph function, the contour map, 3D stereoscopic chart and so on many kinds of engineering drawings, and can be combined perfectly with the administrative map, electronic map and contour map by AUTOCAD.
The application of Surfer in underwater topographic map drawing: Water conservancy in Jiangsu, China.Vol.12 (2005), P.13-14

The production line is composed of a series of subsystems which are related and cooperated each other, such as conifer pulping line, broadleaf pulping line, waste paper line, pulp matching system, additives, vacuum system, white water recycling system and steam system.
The pulp flows from the headbox and comes to the wet net section, after the wet section and vacuum system, much water is extracted and the pulp becomes wet paper sheet, then the wet sheet goes through the press section and dryer section, it becomes finished paper which can be reeled in volumes.
Auxiliary cabinets: additives, vacuum system, white water recycling system, steam system and surface glue coating system.
Programming of Distributed Control System Software Here the Windows2000/Professional operation system is installed in two computers, and MACS programming software can be installed in any one computer, and the computer can be looked as engineer station which can program control layer software and monitoring layer software.

For example, high water impurities is one of the risk sources from material layer, it causes machine to be poor running and causes unusual work.
While the risk sources of the resource are mainly raw materials, natural attributes, such as flammable and explosive hydrogen gas, dissolution of local water and etc.
Before the accident the 2nd unit loaded 200MW with normal operating parameters. 15:06 PM the 2nd unit issued a warning signal, then the turbine driver, monitor, checked the value of stator cooling water pumps, and to determine the signal was an error. 15:08 PM, the BTG plate of the 2nd boiler issued MFT (master fuel removal) action signals as a protection malfunction.

Along with serious blowout and oil spill accident in Gulf of Mexico and Australian waters few years ago, research area related to well integrity has become a global focus.
In cementing engineering, the effective sealing of oil, gas, and water layer is the most important goal.
An important premise of water or gas channeling and sustained casing pressure caused by wellbore integrity failure is: there is pressure difference exists between the annulus and the formation or interlayer.
In fact the cementing quality evaluation is a multidisciplinary technology, combine the wide variety of professional knowledge, we could find out the real reason of cementing quality problems, and carrying out new detection and evaluation method of cementing quality.

These methods involve professional judgment, hard to explain to public and not likely to be accepted in today’s environment.
In the table, it shows that the new selected landfill must buffering 1000m from residential, 100mm from water bodies, 1000m from groundwater sources, and 25km from transfer station.

The following should be considered when corrosion-resistant alloy is selected in accordance with ISO 15156-1[1,2,3]: 1) Temperature during service; 2) Partial pressure of hydrogen sulfide and carbon dioxide in gas phase;3) Existence of elemental sulfur;4) Concentration of Cl- or other halide;5) pH value of water phase.
Sometimes formation water may have a high chloride content, and some wells use high-concentration salt water or natural brine for killing a well.
