1. Nuclear Plant Control System We wanted to design a circuit board with the necessary tools in order to help the operation of a nuclear power plant using an Arduino Uno board. The system includes a photo resistor, a thermometer, 2 buttons which simulate pressure plates to count individuals entering and exiting the plant and an LED screen that helps display important information.

Purpose: In the event of a power failure, one huge sign and cause for panic is the loss of sufficient lighting. The purpose of the photo resistor is used to sense if the lights are on. In the event that the lights go out in the plant, the photo resistor senses this and the program activates emergency lights. Here, we use a small red light, but in a larger application, the same could be done for lights throughout the plant. Lastly, we have two buttons on the board which, when pressed, count and record people entering and exiting, effectively a way for workers at the plant to clock in and out but simplified for this smaller model. At the minimum this helps keep track of the number of people on the premises. They will also function on the same back up power as the emergency lights so as to help with a general count in the event of an evacuation.

In order for conditions in the plant to remain proper for conducting necessary reactions and regular procedures, it’s important for temperature to remain within some levels. With out Arduino Uno board, we set up a temperature sensor that responds to heat. The LED screen displays current temperature as sensed by the sensor and reads off commands based on the temperature. If the temperature is low enough the heat should be on, as it gets higher, the fan is on, and when it reaches a critical temperature, the screen shuts off. In a larger application, this could be used to regulate parts of the plant and shut off appropriate machines in the event that temperatures ran out of control.
