Stabalization of Nuclear Power.

By Peter Bae

Nuclear Power is so safe. I had worked at a manufacturing company for three years. This company makes Nuclear Power Plant’s equipment – auxiliary generator system, debris filter, condensate tube cleaning system, strainers and filter of variety , hangers and supports for pipe. I want to talk to you from purchasing of materials to set up of the products. I show you how to manage the products. So, I’ll introduce manufacturing, testing, and arranging of Nuclear Power Plant’s equipment.

Manufacturing is started by contracting with a customer. If we pass the price tendered from the customer, we’re starting to work on a project. First, I receive the Job Order from the business part of my company, which includes the price of the contract, the term of the contract, who my customer is, what my customer’s requirements are, what equipment I make, and so on. After the technical team draws the equipment by Computer Aided Design(CAD), and the drawing is followed by Nuclear Power Codes(NPC), the team gives the list of materials to the Purchase Team. The Purchase Team also buys all materials following by the NPC. When the materials come into the company, the Quality Assurance(QA) Team inspects that by the NPC. And then the materials are moved to the Manufacturing Team. This Team checks quality and quantity of the materials, then these are moved to the workplace for manufacturing. Workers make the equipment following by the NPC and the drawing. The QA team inspects the equipment everyday. Even if workers make mistakes on something, I don’t need to worry about it. We can find some problems when the QA Team inspects the equipment. Although we can’t find some mistakes, we will find some problems in the process of tests.

Testing is most important for identification of performance. We test differently for importance of the equipment. Tests are divided into visual, pressure, pneumatic, magnetic, ultrasonic inspection, and final tests are painting and visual inspection. When we do the test, almost all my customer’s inspectors attend to the testing place. We also do the test following by the NPC. We set the maximum value of pressure by the NPC. If we didn’t success the test, we must check specifically the equipment until we find problems. If we find some problems quickly, we test it again. If we need a lot of time to find the problems, we make an appointment with my customer when we’re going to meet. After a few days, we meet and test again. If we will pass some kinds of tests, we can move to the equipment to the next process. The next process is Painting. First, workers remove the rust by sand blasting. Second, they paint on the equipment by the NPC. We should wait for the equipment until it’s completely dried. And we will pack the product following by customer’s requirements. We ship the product to the place of shipment.

If our scope is manufacturing and testing, Arranging is the customer’s scope. So we can’t involve the equipment’s arranging, but we check the construction field day after day. Sometimes we visit the construction field to check that they’re arranging the equipment correctly and following by the NPC.

The government makes a decision to establish a Nuclear Power Plant(NPP) for increasing electric power. Many companies are involved to in manufacturing each other’s equipment for the NPP. My company is one of the companies to be able to make Nuclear Power equipment. We need a month to make equipment or sometimes we need over a year. It depends on the equipment’s importance. We should spend more lots of money and time to inspect the NPP’s equipment to compare with the other Power Plant. Because of the stabilization is connected by to people’s lives.

I explained the process of the NPP. We do inspect and test to the equipment step by step and very carefully. So, I am convinced of the stabilization of the NPP.
