SECTION 4: RISK ASSESSMENT
PROPERTY A radiological incident could cause severe damage to the power station itself but would not cause direct property damage outside the station. However, property values could drop substantially if a radiological incident resulted in contamination of nearby areas. A GIS analysis was completed to determine the vulnerability of critical facilities to radiological incident by overlaying the Emergency Planning Zone area with the critical facilities inventory. The resulting vulnerability of critical facilities found within a 10-mile radius of the Harris Nuclear Plant EPZ is summarized in Table 4.139. Table 4.139 – Critical Facilities within the Harris Nuclear Plant 10-Mile EPZ Type Critical Facility Count Structure Value Communications 21 $30,513,999 Energy 60 $75,160,261 Food, Hydration, Shelter 32 $517,187,525 Hazardous Materials 123 $889,145,639 Health and Medical 57 $183,500,329 Safety and Security 67 $269,941,810 Transportation 6 $19,976,201 Water Systems 47 $98,839,141 Total 413 $2,084,264,905

ENVIRONMENT
A radiological incident could result in the spread of radioactive material into the environment, which could contaminate water and food sources and harm animal and plant life.
CONSEQUENCE ANALYSIS
Table 4.140 summarizes the potential detrimental consequences of radiological incident. Table 4.140 – Consequence Analysis – Radiological Incident Category Consequences Public
High levels of radiation could cause serious illness or death. Those living and working closest to the nuclear plant would face the greatest risk. Responders face potential for heightened exposure to radiation, which could cause severe chronic illness and death. An incident at the nuclear plant could interrupt power generation and cause power shortages. Regular operations would likely be affected by the response effort an event would require. The plant itself could be damaged by a radiological incident. Nearby property and facilities could be affected by contamination. Water supplies, food crops, and livestock within 50 miles of the plant could be contaminated by radioactive material in the event of a major incident. The local economy could be affected by a radiological incident. Property values and economic activity could decline as a result. A radiological incident would likely cause severe loss of public confidence given that the hazard is human-caused and highly regulated. Public confidence can also be affected by false alarms.
