The structure provided by the present invention for resisting commercial big aircraft impact protectiving scheme is extremely simple, compared to normal bilayer
The heap-type of containment design need not do big change substantially, only to containment outside crucial items (spentnuclear fuel pond and master control room) exist
Crash direction carries out the double walls protection in part, along with some enhancement measures (door or wall outside such as hole, cofferdam) of part,
It is particularly easy to engineering construction.Compared to the scheme for the arcuated roof for playing Chinese patent application 201820428160.X, exploitativeness is excellent
Gesture is obvious.
Moreover, the protectiving scheme provided by the invention for resisting commercial big aircraft impact, is fully considering that engineering is implementable
On the basis of property, the economy of whole system has also reasonably been taken into account.
Firstly, the protectiving scheme protected object is extremely concise, only protection meets most basic in regulation directive/guide acceptance criteria
Partially (i.e. reactor building borrows the protection of outer layer containment；The master in weary pond, electrical instrument control workshop in irradiated fuel store workshop
Control room and pass through the double walls in part), civil construction amount is greatly saved, substantially increases economy and factory site adaptability.
Secondly, it is also important that for needing to maintain reactor cooling system (packet in regulation directive/guide acceptance criteria
Support system containing the complete sets such as its power supply, cooling), two column Reduced Designs of use are balancing safety, a reliability
With the way of economy, and the workshop where this two column system does not all take additional impact resistance shell measure (to save throwing
Money), but sufficient geographic isolation.
For the way of two column security systems and support system, a wide range of workshop damage caused by this aircraft impact
In the case of, by sufficient geographic isolation, still there is 1 complete column to meet cooling requirement so that containment will not superpressure,
The function and integrality of containment can just be guaranteed.On the other hand, why the present invention uses the way of two column, is combined with
The considerations of safety, reliability, economy, because the quantity of simple increase security column is not an optimal method.From
For regulation, meet single failure it is assumed that the setting of at least two column can meet the requirement of regulation.But security column increased
More, the increase of reliability is but limited, but the cost of economy is double growth.Such as, it is assumed that a column system can
It is 90% by property, then the reliability of two column systems is regarded as 99% (1-10%*10%), then three column are exactly 99.9%
(1–0.13), four column are exactly 99.99% (1-0.14), it is seen then that from a column to two column, 9% reliability is increased, and increases third
Column merely add 0.9% reliability, and increased 4th column increase only 0.09% reliability.Thus, it is merely superimposed
Redundant columns can't bring being obviously improved for safety.And technical solution of the present invention, then it is that have comprehensively considered engineering implementable
Property, safety, the factors such as economy, design the effective nuclear power plant of the complete set obtained and resist commercial big aircraft impact
Protectiving scheme.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.If in this way, belonging to the model of the claims in the present invention and its equivalent technology to these modifications and changes of the present invention
Within enclosing, then the present invention is also intended to include these modifications and variations.
