Yes, a nuclear containment building has pneumatically operated entrance doors with an in-between airlock compartment so that the outside environment is not mingled with the containment's inner atmosphere.
The containment is always maintained at a negative pressure than the normal atmosphere in order to keep the vicinity safe against any untoward airborne radiation escape.
Also the containment itself is designed, constructed and maintained according to the stringent safety design guidelines and standards authenticated and governed by the International Atomic Energy Agency (IAEA).
The employees working in a nuclear environment have to undergo radiological safety training to be qualified to have access to the containment. Their radiation exposure is continually monitored as per the safety guidelines issued by IAEA.

How can nuclear reactors be dangerous?
The purpose of a nuclear reactor is to create and sustain a fission chain reaction in order to produce heat to make steam to drive turbines and produce electrical power (extremely simplified explanation). A fission chain reaction is the interaction of neutrons with fissile materials (elements that can be fissioned). Some enriched fuel (such as uranium-238) is introduced into the reactor core. It produces neutrons as radiation. If more fissile material is present ("fuel" such as uranium-235), that interaction repeats to make more neutrons, and so on. A nuclear reactor is designed to sustain a fission chain reaction and control the rate at which that reaction occurs. The nuclear core of a reactor, where the nuclear fuel is, needs to be shielded so that the radiation and any radioactive components inside do not escape into the general environment. The primary radiation type inside the core is neutron radiation. One of the best shields for neutron radiation is a hydrogen-dense substance, thus pure water is often used. Water, if circulated in a heat sink system, also serves as a heat-removal method (cooling system). The enclosure for the core and the water pool is a containment vessel made out of something that is airtight and which shields against other kinds of direct radiation. Steel is a common material, perhaps supplemented by concrete and other reinforcement to guard against being damaged by an earthquake, explosion, or an airplane impact (for example). There is usually an outer containment building that encloses the reactor containment vessel itself. This is a sort of "second line of defense" in case the reactor is breached. Containment buildings are designed to withstand extremely high internal pressures (such as superheated steam) and forces of almost any direction and realistic magnitude. The specific shape of buildings at a nuclear plant are part of their function. The concave towers that are so symbolic of nuclear power are a common design for cooling towers (and not the reactor core itself). Domes are a common shape for reactor containment buildings for a variety of reasons that have mostly to do with encouraging steam condensation.
What direction should the vapor barrier of insulation be installed?
towards the inside of the building
What is a building material that blocks heat transfer between the air inside and outside?
insulation
What is the examples of energy produce nuclear reactor?
If you mean energy produced by nuclear reactors, then "heat" and "light" would be the answers (Just think of the sun)
Why do you need roof insulation?
Hot air rises, so to keep the heat in the building, you need to insulate the inside of the roof.

What is a dangerous condition caused by overheating inside a nuclear reactor?
A dangerous condition caused by overheating inside a nuclear reactor is called a nuclear meltdown. This occurs when the reactor core is unable to be cooled and may result in a breach of the containment structures, releasing radioactive material into the environment.
Quarantined area of a nuclear plant is called?
It is the containment building in which the reactor vessel and the primary cooling plumbing is housed. During normal operation, radiation levels inside are lethal. Additionally, this structure is designed to "contain" the highly radioactive materials in the event of a major accident.
Does steam from nuclear cooling towers have radioactive elements?
The steam that comes out of nuclear cooling towers is not radioactive. It is produced from the water that is used to cool the reactor, and any radioactive materials would remain inside the reactor containment building and not be released into the environment.

Dangerous condition caused by overheating inside a nuclear reactor?
Overheating inside a nuclear reactor can lead to a meltdown, where the nuclear fuel overheats to the point of damaging the reactor core. This can result in the release of harmful radioactive materials into the environment, posing serious health and safety risks to people and the environment. Emergency response measures, such as cooling systems and containment strategies, are in place to prevent and mitigate the effects of overheating in a nuclear reactor.
How can you survive a nuclear bomb attack?
In the event of a nuclear bomb attack, seek shelter in a sturdy building or underground structure, stay inside for at least 24 hours, and follow emergency instructions from authorities.
How do you destroy a building?
Plastic explosive is what we use today. You put it inside the walls of a building at strategic points and hopefully the building will collapse downwards not sideways. Of course, you could always use brute force (Nuclear bombs etc.)...

What is the containment in a nuclear reactor?
It's fairly literal. The nuclear core of a reactor, where the nuclear fuel is, needs to be shielded so that the radiation and any radioactive components inside do not escape into the general environment.The primary radiation type inside the core is neutron radiation. One of the best shields for neutron radiation is a hydrogen-dense substance, thus pure water is often used. Water, if circulated in a heat sink system, also serves as a heat-removal method (cooling system).The enclosure for the core and the water pool is a containment vessel made out of something that is airtight and which shields against other kinds of direct radiation. Steel is a common material, perhaps supplemented by concrete and other reinforcement to guard against being damaged by an earthquake, explosion, or an airplane impact (for example).There is usually an outer containment building that encloses the reactor containment vessel itself. This is a sort of "second line of defense" in case the reactor is breached. Containment buildings are designed to withstand extremely high internal pressures (such as superheated steam) and forces of almost any direction and realistic magnitude. The specific shape of buildings at a nuclear plant are part of their function. The concave towers that are so symbolic of nuclear power are a common design for cooling towers (and not the reactor core itself). Domes are a common shape for reactor containment buildings for a variety of reasons that have mostly to do with encouraging steam condensation.Another Answer:The first line of defense is the design of the fuel pin, which contains the fuel, preventing its release into the reactor itself. The pin is made of a zirconium alloy that can withstand extremely high temperature and pressure. These fuel pins are about one half inch in diameter and about 12 feet long, depending on the reactor design. They are organized into bundles, then into assemblies, then into the core complex itself.The second line of defense is the reactor pressure vessel. Made of high carbon steel with a stainless steel inner liner, it is often about six inches thick. Along with the core cooling system, it forms the primary pressure boundary for the reactor.The third line of defense is the primary containment. Depending on the reactor design, this is typically a building surrounding the pressure vessel, suppresion pool, and other critical components that is from four to seven feet of hyper structurally reinforced concrete. In the event of a depressurization event of the pressure vessel, the primary containment will hold that release and condense it into the suppression pool.The fourth line of defense is the secondary containment. Again, depending on the reactor design, this is typically a building around the primary containment and its supporting systems such as the emergency core cooling systems and spent fuel pool, that is around two feet thick.All of these containment systems are designed to maximize the length of time you have to restore emergency core cooling before you have an uncontrolled release of radiation and/or radioactivity.There are other lines of defense, but the question only asked about containment.
In what part of a nuclear power plant does nuclear fission take place?
The controlled nuclear reaction takes place in the "core", which for the type of plant can mean a few different things. The core is made up of the fuel, supporting structure, and a moderator. In the United States all plants are of two types (Boiling Water Reactors and Pressurized Water Reactors), both of which use a pressure vessel filled with water to contain the core. The pressure vessel is then places inside a steel and concrete containment structure, which from the outside looks like a cylindrical building, a dome, or a large cube. The containment structure is designed to prevent the release of radioactive material to the environment in the case of a "worst case scenario" accident. In Canada the core is contained within a much larger structure known as the calandria, which is then inside a similar containment to the U.S. style. Reactors in Europe are much like those in the United States, except for eastern Europe (the former Soviet bloc). In all cases there are multiple layers of containment between the radioactive fuel and the environment.
What is the term for energy that comes from inside the nucleus of an atom?
Nuclear energy is the term for energy that comes from inside the nucleus of an atom. This energy can be released through processes such as nuclear fission or nuclear fusion.
