The importance of a strong nuclear safety culture is that without safety reactor accidents are unpreventable. In order to move forward with nuclear power and move it up to a more prevalent source of power we must have public support. Every time there is a incident with a nuclear power plant is slow or stop progression. The Navy has taught me some important pillars with nuclear power and a few that I have picked up while serving, and they are procedural compliance, knowledge, questioning attitude, integrity, and open communication. Individually they seem simple enough but it requires all of them together. Step 8 Once you have completed Step 7 , click on “OK” in the “Safety Moment” dialogue box. (The lesson should now begin. You may turn up the speaker volume or put on the headset to listen to the narration. You may turn off the narration inside the ITS Panel) Step 9a The lesson will now progress automatically, each part of the lesson will advance after it times out, however you may move to the next portion of the lesson by clicking on the “forward” arrow in the ITS box.

Step 9b Throughout the lesson you will see the “Advice” box flash. In this case, click on the “Advice” box to view additional lesson material pertaining to that lesson segment. Step 10 The lesson will end with the statement “You have completed this lesson”. When this statement appears click on “Next” to exit the lesson. Step 11 A dialogue box will appear that states “Lesson finished with score 0.” Please disregard this information and click on “OK”. Step 12 This section of the lesson is now over. Exit the simulator.
