We erected a containment building made up of laws; we passed statutes making the abuse and mistreatment of people by virtue of their race a crime.
This cooperation is expected to gain further momentum with the successful installation of outer dome on the containment building of 1100 megawatt nuclear power plant K-2 which is under construction near Karachi.
According to the Spokesperson PAEC, Shahid Riaz Khan, the huge steel dome weighing more than 360 tonnes, was placed upon the top of the containment building walls, in a prestigious ceremony.
The SIT evaluates the strength of the Reactor Containment Building (RCB), the structure which houses the reactor vessel and major components, by pressurising and depressurising the building to simulate regular and extraordinary conditions.

Other milestones recently "completed safely and successfully" for the scheme, according to Enec, include cold hydrostatic testing and hot functional testing for Unit 2; "the completion of Unit 4's reactor containment building dome and reactor coolant loop pipe welding; and the completion of all major construction work on Unit 3's turbine generator and reactor pressure vessel internals".
Other recent milestones completed safely and successfully include Unit 2 Cold Hydrostatic Testing (CHT) and Hot Functional Testing, the completion of Unit 4's Reactor Containment Building (RCB) dome and Reactor Coolant Loop (RCL) pipe welding, and the completion of all major construction work on Unit 3's Turbine Generator and Reactor Pressure Vessel (RPV) Internals.
The reactor containment building liner dome section was installed and concrete pouring for the dome was completed on Unit 3, and the reactor containment liner plate rings, reactor vessel, steam generators and condenser were installed on Unit 4.
A hypothetical uncontrolled LOCA has been considered to study the effect of the spray system on airborne fission product masses inside the containment building. The continuous leakage of coolant from the reactor pressure vessel during in vessel release phase has been modeled.
The common features of these current studies have focused on the NPP containment building structure and attempted to associate the SSI effect with a seismic fragility analysis of the NPP [18, 19].
In 2017, the reactor containment building liner dome section was installed and concrete pouring for the dome was completed on Unit 3, and the reactor containment liner plate rings, reactor vessel, steam generators and condenser were installed on Unit 4.
