How are nuclear reactors kept safe?

There are many safety procedures put in place to keep a nuclear reactor safe, first of all control rods are used inside the reactor to stop the fission reaction running out of control and melting the reactor core, constant water(coolant) is kept pumping around the reactor cool and to help soak up some of the neutrons and x-ray scans are used to check that there are no natural cracks inside the reactor.


What are the limiting assumptions of C-V-P analysis?

I am interpreting the question as above as Cost Volume Profit(CVP) analysis. If this is not so, my answer below will not be correct. First of all, CVP is used in Finance or Accounting, to describe the behaviour of cost, revenue and profit. Other disciplines also use this analysis, and will be called a different name. In Business Management, it's often called Break Even Analysis. One of limiting assumptions of CVP analysis is the assumption of a linear function of the variable cost and total cost. This means that the cost of a business will increase in a proportional manner, if I make 2 units of output, the cost is 4, if I make 4 units of output, the cost is 8. While this may be possible in theory, it reality, it's not so. If we assume that the cost is linear, the Variable Cost and the Total Cost will be a straight line. In reality, the variable cost doesn't increase in along a straight line. ( not so perfect in reality ). Apart from that, the CVP analysis also assumes that there are no stocks present. The analysis just shows that goods are sold and the company has no stocks kept. Although these can be seen as a limiting assumptions of the CVP analysis, it's important to understand it provides an understanding to students who are new to it. In Economics, the CVP analysis is more complicated, with the variable cost and the total cost function a curve. This means that the cost will fall initially and then increase later. Apart from that in other Ecnomics, costs are considered with the short run and long run perspective. Costs may not be the same in short run and long run.
