Here is a summary of the key points in 1⁄2 page: The Bataan Nuclear Power Plant (BNPP) was built in the Philippines in the 1970s but has never been operational. There were several issues that prevented its operation: 1. Safety concerns - The plant was built during the 1970s before stricter safety standards were established after the Three Mile Island accident in 1979. International experts raised doubts about its ability to withstand earthquakes and other natural disasters common in the Philippines. 2. High costs of operation - Estimates showed the plant would incur huge operating costs, especially for maintenance and purchasing nuclear fuel. These costs were deemed too high for the Philippine government and electricity consumers. 3.

2. Question 1
Unstable nuclei
undergo this process to
become stable.

3. Question 2
It is a kind of decay
where 2 smaller nuclei
come together to form a
more massive nucleus.

4. Question 3
It is a kind of decay
where 1 massive nucleus,
separate when
bombarded by a
neutron.

5. Question 4
It is a kind decay
where the atomic mass
of the daughter nuclei
decreases by 2.

6. Question 5
It is a kind of decay
where the atomic mass
of daughter nuclei
increases by 1.

15. Difference between mass of
reactants and mass of products
Mass defect

16. Convert mass defect into energy
Binding Energy

17.  Mass defect- is the difference
between the mass of the product
and reactant when reaction
takes place.
 Binding energy is the mass
defect in terms of energy.

mass go in a fission
reaction? What is the
application of mass
defect and Binding
Energy?”
