Description

A kind of anti-radiation mortar for being used to isolate nuclear leakage
Technical field
The present invention relates to a kind of anti-radiation mortars, are specially a kind of anti-radiation mortar for being used to isolate nuclear leakage.
Background technology
Nuclear power be it is a kind of clean, the highly efficient and relatively safe energy.Nuclear leakage accident occurs for nuclear power station, refers to nuclear reactor In radioactive substance leak, cause environmental pollution and the public made to 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 Substance, a kind of energy that radioactive substance is launched with ripple or particulate form are just named nuclear radiation, and nuclear explosion and nuclear accident have core Radiation.It has tri- kinds of forms of radiation of α, β, γ.α radiation can be blocked as long as with a piece of paper, but harm is big in suction body;β is radiated It is high-velocity electrons, skin is burnt apparent after being stained with;γ radiation is similar with X-ray, can penetrate human body and building, damage effect distance Far.
It is many that universe, nature can generate radioactive substance, but endangers 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, cause interior radiation, and y radiation can penetrate certain distance and be absorbed by organisms, and be 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, diarrhea etc..Sometimes it can also increase cancer, distortion, heredity lesion incidence, influence the health of several generations.Generally It says, the radiation energy that body receives is more, and radiation disease symptoms are more serious, 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 are according to the technology path of Chinese development nuclear power, and selection technique is ripe, security Reliably, 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 divide at 2016 2 months 24 days 19 16 seconds, ML3.2 grades of earthquakes occurred within the border for yiyang, hunan city Taojiang County, 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 provides (revised edition in 2015)》, ML3.2 level conversions are into M Earthquake magnitude is 2.5 grades, and China Seismological Network Center speed bid quotation standard has not yet been reached in this secondary earthquake, is exactly this small earthquake, there is China The peach blossom river nuclear power station of the title of " the first nuclear power station of inland " 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, related nuclear power The safety stood has to draw attention, as geological disaster trigger nuclear leakage when this how because right, this is that those skilled in the art compel The technical issues of cutting solution.
It is below the accident of some nuclear leakages all over the world over the years:
On March 28th, 1979 three miles of island nuclear power plant accidents: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.
Chernobyl nuclear leakage on 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 explode, more Explosion occurs and triggers big fire immediately, and radioactive fallout is caused to get into the air.It is reported that the radioactivity dirt that this time accident generates Drop object quantity is 400 times that the atom bomb thrown in Hiroshima is discharged.
On March 11st, 2011 the first Nuclear Power Station of Fukushima, Japan leakage accident:It is influenced by eastern Japanese violent earthquake, 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 is occurring " leakage accident ";Fukushima The company of Tokyo Electric Power of operator of first nuclear power station is release memory space, makes the first nuclear power station of Fukushima of generation nuclear leakage accident The higher contaminant water of concentration can be stored, 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.
The content of the invention
The purpose of the present invention is in view of the above problems, providing a kind of anti-radiation mortar for being used to isolate nuclear leakage, have good Good hard and soft characteristic, it is not stratified, do not isolate, not sagging, condition of high temperature lower structure stability is good for its, it is corrosion-resistant to be provided simultaneously with, wear-resisting The features such as damage, the wall being built into using anti-radiation mortar of the present invention can carry out isolated screen to tri- kinds of rays of nuclear radiation α, β, γ It covers, the people positioned at wall another side or the nuclear radiation harm of object is greatly reduced.
