The Problem
On April 16, 1986, at 1:23 a.m., Chernobyl’s reactor # 4 exploded, resulting in the worst nuclear disaster the world has ever known. The explosion spewed a cloud of radiation over much of the Northern Hemisphere, forcing hundreds of thousands of people from their homes in heavily hit areas of Ukraine, Belarus, and Western Russia.
Initially, the Soviet government failed to tell the public what had happened, and it ignored the urgent need to evacuate nearby residents. The government also failed to teach residents and cleanup workers how to protect themselves against radiation, which increased the risks of injuries and illnesses significantly. In response to the disaster, the government quickly built a shelter, named the Sarcophagus, to cover the damaged rector. The Sarcophagus has been crumbling and leaking radiation in recent years.
During a ceremony to commemorate the 26th anniversary of the Chernobyl disaster, the Ukrainian President, Viktor Yanukovych, announced plans for the assembly of a gigantic arch-shaped steel containment building that will cover the remnants of the exploded rector. The structure, weighing 20,000 tons and large enough to house New York’s Statue of Liberty, is due to be completed in 2015. Meanwhile, despite the Chernobyl disaster, Russia is continuing with its plans to build the former Soviet Republic’s first nuclear power station in the town of Ostrovets, near the Lithuanian border. The town’s citizens strongly oppose these plans.
Mission Deliverable
Your mission is to develop a speech that convinces the citizens of Ostrovets that the former Soviet Republic’s first nuclear station will be safe. Many of these citizens remember the Chernobyl disaster and are very concerned that this incident could happen again. Your speech should reflect a balanced view of both the citizens’ and the government’s needs and concerns.
Guiding Questions
1. Are nuclear technologies really safe?
2. What role should the government play in protecting citizens from nuclear disasters?
Key Concepts Addressed
The concepts of the atom and the nature of matter originated with Greek philosophers more than 2,000 years ago. These ideas, though not scientifically tested, formed the basis for later scientists to build upon and develop modern atomic theory.
