Description

The complex task of assessing the sustainability of the communication object in emergencies
Option 2
Setting.
1.Otsenit situation at the facility due in cases of exposure to damaging factors in emergency situations.
2.Otsenit life safety of facility personnel, residents of the village and the stability of operation of the facility (the elements of an object, and communications in general) for emergencies.
3.Razrabotat engineering measures to improve the health and safety of the population and personnel and the sustainability of the elements of an object and a whole disaster.
General characteristics of the object.
Communication object is placed on the outskirts of the settlement Ukrainians, in which a person lives. Residents of the village are provided with gas masks 60%. Dwelling houses in the village Ukrainians storey, wooden, 2 and 4-storey brick with attenuation Khosla = 7.
Buildings communication object 2-storey reinforced concrete with an attenuation factor Khosla = 7.
Power supply to the object is carried out by two independent transformer substation in underground cables.
Emergency diesel power plant (DES) is located at the site in a one-story brick building.
The antenna device mounted on wooden and metal supports.
The connecting lines from the DC public network (GSS) to RPtsD laid underground cable.
The lines of communication to the CMS are laid underground cable and air communication lines on wooden poles.
Duty shift at the facility is 55chelovek. Security masks 100%.
Initial data:
At a distance of 2.5 km from the settlement Ukrainians located warehouse industrial explosives (TNT) with a total weight equivalent to 40 kilotons.
Diesel fuel is stored in tanks, tanks on the premises (fuel storage) with a total weight of 150 t. At a distance of 1.5 km from the DPP.
At a distance of 4.4 km from the locality Ukrainians located chemical plant, where 80 tons of ammonia with a specific density of t / m3. SDYAV stored in bunded tanks. The wind speed in the surface layer 3 m / s.
In the event of an accident, the destruction of a nuclear reactor at the plant beginning of exposure to be expected after 3 hours after the accident. The level of radiation at this time (early exposure) amounts to 5 R / h.
The staff works in an open area in the room, while the 5 h. Permissible radiation dose to personnel management and facilities installed is 4 Baer.
Residents of the settlement Ukrainians after receiving the signal "Radiation danger" must be in homes and basements (MDP) h.
In the area of \u200b\u200bthe settlement Ukrainians perhaps an earthquake intensity I = 6 points.
