Subject:
WATTS BAR NUCLEAR PLANT (WBN) UNIT 2 - RADIOLOGICAL EMERGENCY PLAN ADDITIONAL INFORMATION
Reference:
- 1. TVA letter dated March 4, 2009, "Watts Bar Nuclear Plant (WBN) Unit 2 -
Operating License Application Update" This is in response to a verbal request from NRC staff. In Reference 1, TVA indicated that Appendix E of TVA's Radiological Emergency Plan (REP) provided references to the applicable state radiological emergency response plans. NRC staff requested a copy of the Tennessee emergency response plan.
The Tennessee Emergency Management Agency (TEMA) provides a comprehensive offsite response program in the event of a radiological incident at WBN. The plan that guides all aspects of the offsite response is entitled the Tennessee Multi-Jurisdictional Radiological Emergency Response Plan (MJREP). This plan is based upon actions taken in the event of an actual emergency at the plant. An annex to the plan addresses evacuation of permanent residents, transient population, and special population (school and day care centers) within the 10-mile Emergency Planning Zone (EPZ). In an effort to inform and educate citizens, information is distributed on an annual basis through an "Emergency Information Brochure/Calendar" mailed to all residents within the 10-mile EPZ. An example is included in.

The Prompt Notification System around Watts Bar. If you hear the sirens, tune to a local radio or listen for instructions.
television station for news and instructions.
We expect Watts Bar Nuclear Plant to operate safely. However, if an emergency occurs at the plant, TVA will inform state officials at once.
In-depth emergency plans have been prepared by TVA, the State of Tennessee, and your local Emergency Management Agency.
These plans are in place to protect your health and safety, and this calendar is a part of those plans because we want you to be prepared, know what the sirens mean, and know what you should do if you hear them.
If needed, the Prompt Notification Systermwill be activated quickly to inform the public of any potential threat. The Prompt Notification System uses sirens and tone-alert radios to notify the public to tune their radios or televisions to an Emergency Alert System
(_AS) station. The EAS station will provide information and emergency instructions for the public to follow.
The Emergency Alert System includes local radio and television stations, NOAA weather radio, and the cable-TV interrupt system.
Fixed sirens provide coverage out to approximately 10 miles The sirens and other warning systems are operated by the Tennessee Emergency Management Agency (TEMA) and may be used to warn residents of an emergency other than an incident at Watts Bar. For example, the sirens may be used to warn the public of floods, tornadoes, or other natural or man-made disasters.
If you note a problem with one of the sirens, please notify your county or state Emergency Management Agency using the numbers listed on page 1.
1l If you hear the sirens Check it out - it could be only a test. Siren tests occur in your area on the first Wednesday of each month at noon. If there is severe weather in the area at the time of a scheduled test, the sirens may not be tested.
Remember: Hearing a siren or tone-alert radio does not mean you should evacuate. It means turn on your radio or television and Tune to your local radio or television station and listen for details. WUSY-FM (100.7) in Chattanooga and WIVK-FM (107.7) and WNOX-AM (990) in Knoxville are the primary and alternate EAS stations in the area and are monitored by other stations. A real warning could mean fire, tornado, chemical spill, nuclear incident, or other emergency.
Most radio and television stations in the area participate in the EAS and will be making announcements. NOAA weather radio (162.55 MHz) will instruct listeners to tune to one of these stations.
Check on your neighbors.
Do not use the phone unless absolutely necessary. The phone lines need to be open for emergency workers. Do not call 911 for information if you hear the sirens.
If the warning involves an incident at Watts Bar, you might be advised to go indoors and close all windows, doors, and other sources of outside air. Or you may be advised to leave (evacuate) your area. In either case, see page 3 for additional information.

r For farmers and home gardeners If a major incident happens at Watts Bar Nuclear Plant, the Ten-nessee Department of Agriculture will issue periodic information You should stay tuned to an EAS station for these announcements.
Information on actions you can take to protect crops and livestock is available from your County Agricultural Extension Agent.
Your crops
- An Unharvested crop is hard to protect. But normal harvesting and processing may still be possible if time permits.
- Crops already harvested will be safer if they are stored inside.
- You should wash and peel vegetables and fruits from your gar-den before use if they were not already harvested.
To protect your livestock
" Provide as much shelter as possible. If you do not have enough space in barns or sheds, use natural shelters such as wooded lots or culverts.
" Take care of milk animals first.
" Provide plenty of food and water and make sure shelters are well ventilated.
- Use stored feed when possible.

W General information How emergencies are classified If there is an incident at Watts Bar Nuclear Plant, it will be placed in one of four emergency categories from least serious to most serious. These four levels have been set by the United States Nuclear Regulatory Commission and adopted by the State of Ten-nessee and TVA.
The four emergency levels are described below in order from least to most severe.
- 1. A Notification of Unusual Event is the least serious. Because of strict federal laws, any event out of the ordinary is reported to federal, state, and local authorities. The event poses no threat to you or to plant employees, but emergency officials are notified.
- 2. An Alert is declared when an event has occurred that could reduce the level of safety of the plant, but backup plant systems still work. Emergency agencies are notified and kept up-to-date, but no action by the public is necessary.
- 3. A Site-Area Emergency is declared when an event involving major problems with plant safety systems has progressed to the point that a release of some radioactivity into the air or water is possible. The sirens will be sounded. If they are, you should listen to radio and television stations for details.
- 4. A General Emergency is the most serious of the four classifi-cations and is declared when an event at the plant has caused a loss of safety systems and is likely to lead to a release of radiation into the environment. State and local authorities would take action to protect residents living near the plant. People in affected areas would be advised to stay indoors or to evacuate.

Glossary What Is radiation?
Background radiation - This is radiation from natural sources. It comes from the sun's rays and it's in the ground, building materials, and the human body.
Core - The central part of a nuclear reactor that contains the uranium fuel.
Fission - The nuclear process in which a heavy atom, such as uranium, splits into fragments.
Fuel assembly -A collection of rods that contain the nuclear fuel pellets. The fuel pellets produce heat to make the steam used to generate electricity.
Fuel pellets -Thimble-sized uranium dioxide pellets used In nuclear power generation. Each pellet contains about the same amount of energy as that produced from burning one ton of coal. A modem reactor core may contain up to 17.5 million pellets.
Fuel rods - Holiow tubes that contain stacks of uranium dioxide fuel pellets. These rods are bundled together to form fuel assemblies.
Half-life - The time required for a radioactive substance to lose one-half of its radioactivity. Half-life can vary from minutes to years, depending on the substance.
Radiation is energy traveling in the form of invisible particles or rays after the breakdown of radioactive atoms. Everyone is exposed to small amounts of radiation every day. Air, water, food, and sunshine are a few sources of natural background radiation.
Most people receive a dose of about 300 to 400 millirems of background radiation a year. "Millirem" is a term used to measure the effect of radiation on the human body.
Radiation also comes from other sources. Color televisions produce about 1 millirem of radiation every year. Medical procedures such as x-rays and diagnostic tests can result in 20 to several thousand millirems of radiation a year, depending on a person's treatment for disease or injury.
People are concerned about radiation exposure because it can after or damage human-cell structure. That is why workers at nuclear power plants are carefully monitored and trained to limit their exposure to a level that is as low as is reasonably achievable.
The Nuclear Regulatory Commission, which issues licenses to all nuclear power plants, has set a maximum safe individual dose of 5,000 millirems a year, measured over the entire body. To avoid coming even close to this level, TVA work procedures set an administrative limit of 1,000 millirems per year for any worker, with any additional dose requiring written approval.
A nuclear power plant's containment building, reactor vessel, and fuel assemblies are barriers designed to contain radiation and protect plant workers and persons living near the plant from any exposures to elevated levels of radiation. Repeated surveys around TVA's operating nuclear plants have shown no detectable increase in radiation above normal background levels.

How Watts Bar works Steam Generator Rier Watts Bar operates much Ike a fossil-fueled power plant with one substances that absorb neutrons. Control rods are made of mate-major difference. In a fossil plant, coal, oil, or gas is burned to make rial that absorbs neutrons and can be moved in and out of the fuel heat. The heat turns water into steam, the steam drives a turbine, and core. When inserted into the core, they stop the chain reaction.
the turbine spins an electrical genertor producing electric power The operation is the same at Watts Bar, eaoet the heat is provided by a process called fission. The fuel for Watts Bar is uranium, which is made into pellets and sealed inside long metal tubes, called fuel rods. These rods are placed into a reactor vessel, making up a fuel core. In addition, some rods are designed to collect tritium for use by the U.S. Department of Energy.
When a uranium atom is struck by a small particle called a neu-tron, it can split (fission), giving off heat and more neutrons. Those neutrons can strike other uranium atoms, causing them to split and continue the chain reaction. The reaction is started and stopped by i Is physically M S.E for the nuclear fu at Watts Bar to explode like a nuclear bomb. The fuel for Watts Bar and most other nuclear power plants is only about 3 to 5 percent fissionable uranium.
Nuclear weapons contain in arcess of 90 percent fissionable uraninm.
Thus, there is not enough fissionable material for an explosion. The illustrabton above shows how the heat from the fission process is used to make steam and generate electrilcity at Watts Bar In the primary loop (yellow), water is pumped through the reactor core and is heated. The water is kept under high pressure to prevent it from boiling. The heated water is pumped to a steam generato, where the heat is transferred to a secondary loop of water.
The water in the secondary loop (inkW boiis to produce steam.
The steam is pipe to the turbines. The force of the expanding steam drives the turbines, which spin a magnet in a coil of wire (the geneator) to generate electric power.
After passing through the turbines, the steam is converted back to water by circulating it around tubes carrying cool water from Chicamauga Reservoir (blue). The condensed steam-fow wa-ter-is pumped back to the steam generator to repeat the cycle.
The condenser cooing water is passed through the cooling towers before being recycled through the plant. The three water systems are separate from each other. Most important, the radioactive water in the primary loop is not permitted to mix with the other nonradioactive water systems.
