Description

A kind of anti-radiation mortar for isolating nuclear leakage
Technical field
The present invention relates to a kind of anti-radiation mortar, specially a kind of anti-radiation mortar for isolating nuclear leakage.
Background technology
Nuclear power is a kind of cleaning, the highly efficient and relatively safe energy.There is nuclear leakage accident in nuclear power station, refer to nuclear reactor In radioactive substance leak, cause environmental pollution and make the public be subject to radiation hazradial bundle.Therefore, some reply nuclear leakage is grasped Knowledge is provided against any misfortune or necessary.Influence of the general situation of nuclear leakage to personnel shows nuclear radiation, also referred to as radioactivity Material, radioactive substance is just named nuclear radiation with a kind of energy that ripple or particulate form are launched, and nuclear explosion and nuclear accident have core Radiation.It has tri- kinds of forms of radiation of α, β, γ.As long as α radiation can just be blocked with a piece of paper, but harm is big in suction body;β is radiated It is high-velocity electrons, burn is obvious after skin is stained with;γ radiation is similar with X-ray, can penetrate human body and building, damage effect distance Far.
Universe, nature can produce radioactive material many, but harm is all less big, only nuclear explosion or nuclear power station thing Therefore the radioactive substance of leakage could cause injures and deaths to personnel on a large scale.Radioactive substance can be sucked by breathing, skin wound Mouth and alimentary canal are absorbed into vivo, causing interior radiation, y radiation to penetrate certain distance and be absorbed by organisms, and are subject to personnel outer Irradiation injury.The symptom that interior external exposure forms radiation sickness has:It is fatigue, giddy, insomnia, rubefaction, ulcer, bleeding, alopecia, white Blood disease, vomiting, diarrhoea etc..Sometimes can also increase cancer, distortion, heredity lesion incidence, influence the health of several generations.Typically Say, the emittance that body receives is more, its radiation disease symptoms is more serious, and carcinogenic, teratogenesis risk is bigger.
Peach blossom river nuclear power station is found on May 21st, 2008, and project factory site is located at Hunan Province Yiyang City Taojiang County Zhan Xi townshiies Lotus leaf mountain, provides water right bank.Peach blossom river nuclear power projects according to Chinese development nuclear power technology path, selection technique is ripe, security Reliable, the million kilowatt advanced pressurized water reactor nuclear power generating sets of good economy performance, planning installed capacity is 4,000,000 kilowatts, and 4 units are same Phase builds.Project takes " owner be responsible under engineering company's over contract " management mode for construction.48 points at 2016 2 months 24 days 19 16 seconds, there is ML3.2 grades of earthquake in yiyang, hunan city Taojiang County within the border, and earthquake centre is located at Taojiang County domestic (112.04 degree of east longitude, north latitude 28.56 degree), 7 kilometers of the depth of focus.According to《Rapid earthquake information report technical management specifies (revised edition in 2015)》, ML3.2 level conversions are into M Earthquake magnitude is 2.5 grades, and it is accurate that this secondary earthquake not yet reaches CENC speed bid quotation, exactly this small earthquake, there is China The peach blossom river nuclear power station of the title of " nuclear power station of inland first " has been shifted onto on the teeth of the storm again, to this secondary earthquake, district government and phase Life is closed to be paid much attention to.But fortunately current earthquake intensity is not high, does not cause large effect to nuclear power station, relevant nuclear power The safety stood has to draw attention, when such as geological disaster triggers nuclear leakage this how because right, this is that those skilled in the art compel Cut the technical problem of solution.
It is below the accident of some nuclear leakages all over the world over the years:
The three miles of island nuclear power plant accidents of March 28 day in 1979:The radioactive material that No. 2 reactors of three miles of island nuclear power stations occur The matter accident of leaking is nuclear power plant accident the most serious in American history, although this time accident does not cause casualties.
The Chernobyl nuclear leakage of April 26 accident in 1986:Chernobyl nuclear leakage accident is referred to as in history The nuclear power station disaster of most serious.Morning on April 26th, 1986, the reactor of Chernobyl Plant the 4th explodes, more Blast occurs and triggers big fire immediately, causes radioactive fallout to get into the air.It is reported that, the radioactivity dirt that this time accident is produced Drop thing quantity is 400 times that the atom bomb thrown in Hiroshima is discharged.
The first Nuclear Power Station of the Fukushima, Japan leakage accident of on March 11st, 2011:Influenceed by the violent earthquake of eastern Japan, Fukushima, Japan Building where first reactor of nuclear power station 1 explodes, and Japanese government recognizes on the 13rd, the impaired Fukushima the in violent earthquake One unit of nuclear power station 2 may occur " accident ", and the high temperature nuclear fuel of No. 2 units occurs " leakage accident ";Fukushima The company of Tokyo Electric Power of operator of the first nuclear power station is release memory space, makes the nuclear power station of Fukushima first of generation nuclear leakage accident Concentration contaminant water higher can be deposited, 11500 tons of contaminant waters containing radioactive substance are poured into sea, subsequent Western Pacific Partial Sea Area detects exceeded 300 times of radioactive element.
