Correct option: c) Clothes that are neat and clean

The reactor building is divided into two areas. They are V₁ and V₂. 

V₁ – Dry volume area. 

V₂ – Wet volume area.

V₁ area includes F/M vault, boiler room, and entire dome area. Rest of the areas in the reactor building is V₂ area. V₁ and V₂ are connected by vent shaft through suppression pool. 

F/M vault is a V₁ area and F/M maintenance bay is a V₂ area. Usually when there is an accident in F/M vault the pressure is relieved through boiler room through suppression pool and the uncondensed gases to V₂ area. When the reactor is in operation and if we open the F/M vault door, suppose of there is an accident in F/M vault the pressure released directly goes to F/M maintenance area, which is a V₂ area. Thus pressurizing the entire building.

Unit # 1 end-shield is made of nickel steel, which had a nil ductility temperature of -100°C while commissioning. After 30 years of operation this will rise to +32°C, because of radiation exposure. To avoid the failure of end shield of MAPS Unit # 1 the temperature of the end-shield should be maintained at 68°C always. MAPS 1 end-shield cooling system is operating at elevated temperature. But in MAPS Unit #2 this problem is not existed because in this unit end-shields are made up of stainless steel.

Non-Verbal Communication includes the use of body language, facial expression, and gestures to convey information to others.

Correct option: d) Stand sideways to a customer with your arms folded

Mass and energy are interchangeable. When mass is lost there is a substantial gain in energy and when energy is lost there is a increase in mass. 

 Energy = mass*C² 

E = MC² 

Where C is the conversion factor = 3*10¹⁰ (velocity of light) 

C² = 9*10²⁰

a. H₂ 

b. D₂ 

c. H₂O 

d. D₂O 

e. Beryllium 

f. Graphite.

The functions of a good moderator are .

a. It has to thermalise neutrons effectively. 

b. There should be only a minimum absorption of neutrons. 

c. It should not be toxic. 

d. It should not be inflammable.

 In case of Hydrogen (H₂) though it is a effective sheatherer it cannot be used as a moderator because it is a gas and there is a lot of distance between atoms. A neutron cannot meet the nucleus in a definite manner.

For D₂ also the same problem as this is also gas and it cannot be used as a moderator. In case of H₂O it is a good scatterer but is absorbs neutrons. Its moderation ratio is 72. So it cannot be used as a moderator.

In case of D₂O though it is not as effective scatterer as that of H₂O it has minimum absorption of neutrons. It has a moderating ratio of 21000. This is an ideal moderator.

In case of Beryllium it is a toxic material. Therefore cannot be used. Graphite absorbs neutrons and is inflammable and therefore cannot be used. So from the above statements the D₂O is the good moderator material. 

Activity of an Iodine – 131 = 10 curies 

To find number of half-lives for coming it to 625 millicuries, 

10 * 1^st | = 5 (1^st half-life) 

5* | = 2.5 (2^nd half-life) 

2.5 * | = 1.25 (3^rd half-life) 

1.25 * | = 0.625 (4^th half-life) 

 So during 4^th half-life the Iodine – 131 reduces to 625 millicuries.

0.025 eV (energy volt) 

1.00759 amu (atomic mass unit) 

Atomic number: The atomic number of an atom is the number of protons in that atom. 

Example – Hydrogen has one proton and its atomic number is one (1). – Uranium has 92 protons and its atomic number is 92. 

Mixture: It is a substance formed by different elements and these elements can be separated by physical methods. 

Example – Air is a mixture of oxygen and nitrogen and these can be separated by physical methods.

The purpose of inlet manifold is to introduce heavy water to the calandria with low velocity to avoid mixing. That is stratified flow of D₂O is obtained b inlet manifold. Thus the temperature is kept minimum. It is made of zircalloy

For the purpose of maintenance of PHT pipe valves, boiler inlet valve the level of the coolant should be below the valve to prevent the coolant coming out of the system. This is called the header level control and achieved by means of manual operation of valves and shutdown cooling pump.

The purposes of bleed condenser are, 

a. To cool the bleed water, which goes to bleed cooler.

b. To provide cool hot water to the PHT purification system. 

a. Impeller – To reduce the water flow. 

b. Self-injection Hx – Cools the water in case of leakage. 

c. Gland supply – Cools the seals. 

d. Primary and secondary seals – sealing the pump. 

e. Thrust bearing – To take the axial thrust. 

When the PHT power fails, it takes two minutes for DG to come to full power. The circulation is maintained by flywheel, which increases the de-acceleration and maintains the flow for two minutes.

If there is a station blackout the flow is maintained by thermo-symphoning by which more denser cold water comes down and less denser hot water goes up by convection method. 

During loca there is provision for taking D₂O from the moderator system, which is connected to PHT system for fuel cooling and there is one more option for the cooling of the fuel from the fire water system.  

Piping – carbon steel. 

Pressure tubes – zircalloy-2 

Fuel cladding – zircalloy-2 

End shield – stainless steel. Etc.  

During normal operation process LP water is used in moderator heat exchangers, which transfers heat to seawater. During class IV failure firewater is used for the moderator heat exchanger. 

The purposes of moderator D₂O are, 

a. To thermalise neutrons to maintain criticality. 

b. Emergency core cooling when PHT fails. 

c. Structural cooling. 

At the state level there is a State Level Disaster Management Committee consisting of the senior secretaries of various departments and the representatives of NGOs. At the national level, there is a Crisis Management Committee, headed by the Cabinet Secretary and the secretaries from the major departments of the government.

1. astronomy = scientific study of the universe 

2. astrophysics = the physics of astronomical objects 

3. astronaut = space traveller 

4. aster = Star-shaped structure in cells 

5. asterisk = star shaped symbol

7. asteroid = rocky object orbiting the sun

Its geographical location and geological formation make India more vulnerable to disasters. Its long coastline, snow-covered peaks and high mountain ranges and the perennial rivers of the north combine to make the problems worse. India has only 2% of the total geographical area, but it supports 18% of the total population. So, there is a great pressure on the natural resources. This directly or indirectly leads to disasters like floods, droughts, landslides and earthquakes.

I don’t agree with The view of the author that that disaster management in India is the responsibility of the state and central governments. I fully agree with the view that the people of our country should have a role in preventing and managing disasters. Preventing natural disasters may not be possible but we can do many things to reduce the impact of such disasters. Without the people’s active cooperation, no scheme of any kind will succeed.

It is an applied predicate calculus specifically tailored for relational databases proposed by E.F. Codd. E.g. of languages based on it are DSL ALPHA, QUEL.

1. The tuple-oriented calculus uses a tuple variables i.e., variable whose only permitted values are tuples of that relation. E.g. QUEL 

2. The domain-oriented calculus has domain variables i.e., variables that range over the underlying domains instead of over relation. E.g. ILL, DEDUCE.

The overloading helps to apply polymorphism because Function overloading means two or more functions having same name but different types of arguments or different number of arguments. Whereas polymorphism refers to “one name having many forms of an object behavior depending on situations.

Function overloading is normally used when several functions of the same name perform identical tasks on different data types. The overloading function helps to reduce the use of different names for many functions.

The developer of the program can use one function name to give function call to one in many functions and C++ select the appropriate function by checking the number of parameter and type of parameters. This reduces the selecting a function block to give a function call by the user.

It is easier to understand the flow of information that helps in faster debug. Easy program maintenance. There can be a common interface between programs and real-world objects.

The different types of inheritance are single inheritance, multilevel inheritance, hierarchical inheritance, multiple inheritance and hybrid inheritance.

1. Single inheritance:
A derived class with only one base class is called single inheritance. For example, If A is base class then class B derive from base class A.

2. Multilevel inheritance:
A class can be derived from another derived class which is known as multilevel inheritance. For example, The derived class C inherit B class whereas B is derived from class A.

The various data types supported by DBMS are integer, single precision, double precision, character, string, memo, index, currency, date and text fields.

The ports are used to connect external devices like printers, keyboards or scanners and interface with the computer.
COM/Serial ports: [Component Object Model]
It is used for connecting communication devices like modems or mice. Serial ports provide the serial transmission of data of one bit at a time. There are two types namely, COM ports – 9 pin ports and 25- pin ports.

The HTML is used to create web pages.

In this mode, communication can take place between sending and receiving end in both directions, but only one direction at a time (not simultaneously). Example, walkie-talkie device.

1. Syntax for delete:
DELETE from tablename WHERE condition;

2. Syntax for insert:
INSERT INTO tablename (col1, col2, …) VALUES (val1, val2….);

The logical operators in SQL are ALL, AND, ANY BETWEEN, EXISTS, IN, LIKE, NOT, OR, IS NULL, UNIQUE.

1. Data:
Data is a collection of facts, figures or statistics. Data is transformed into meaningful information. It is raw material of information.

2. Information:
It is processed data with definite meaning. Information gives meaning.

The communication mode is the technique of transmitting and receiving signals between the sender and receiver.

Simplex mode:

The communication occurs in one direction only. For example, radio receiver and radio transmitter.
