It should be noted that each power station in this country that employs this telemetry system has had 10-16 remote sensor stations.
Outside of the U.S.
(e.g. Finland or Korea) an average of 10 is com-mon.
The State of Illinois estimates that their cost of the telemetry system average calls for two million dollars / reactor.
This was due to the cost of development of the, system, as well as the fact that the cost of the remainder of the Radiation Control Program was included in their budget process.
The Massachusetts' estimates above are based on a proposed program for monitoring a single nuclear power plant.
Information sheets on the Illinois emergency planning and assessment activities are attached.

THE ILLINOIS PLAN FOR RADIOLOGICAL ACCIDENTS l
The Illinois Plan for Radiological Accidents (IPRA) details the program for state wide, integrated management of nuclear i
accidents, especially those which might occur at a nuclear power reactor. The primary purpose of the Plan is to provide a coordinated response by state and local governmental ofilclals for the protection of the citizens of Illinois. The Plan includes:
general planning to cover the urgency of any nuclear accident; site specific planning to protect citizens living near nuclear plants; a concept of operations so that the Plan can be effectively carried out; and an effective allocation of resources and personnel.
The Plan pre-assigns the duties and responsibilities that would be taken by all the respondents to a nuclear accident, thus enabling actions to be made quickly and ef ficiently.
The lilinois Department of' Nuclear Safety (IDNS) and the Illinois Emergency Services and Disaster Agency (lESDA) share the responsibility for developing the Plan. Specifically, the IDNS is responsible for the technical functions of this effort, and the lESDA is responsible for the operational aspects.
The Plan is updated annually for accuracy, and appropriate components are distribute d to 18 state, 10 county, and 37 municipal organizations in Illinois, as well as to appropriate organizations in the contiguous states of Iowa and Wisconsin.
Major operations specified in the Plan include:
o Accident Classification.
o Operational Response Level, o initial Notification.
o Accident Assessment.
o Command and Coordination Responsibilities, o Protective Actions:
Shelter; Evacuation; Traffic and Access Control; and Food, Water and Milk Control.
o Parallel Actions:
Public Information; Radiation Exposure Control; Law Enforcement and Crime Prevention; Fire and Rescue; Emergency Medical Services; Social Services; and Re entry.
o Operation Centers: Location and Responsibilities, o Notification of the Public.
I o Emergency Announcements:
Information, Shelter, and Evacuation.

REACTOR PARAMETER DATA LINK l
l The Illinois Department of Nuclear Safety (IDNS) has installed a direct data communication link between the Department's l
central computer and each nuclear reactor's control room computer for the monitoring of nuclear power reactors and their safety systems.
This DNS Data Link (DDL) was developed for early notification of events that could lead to nuclear accidents.
DDL is an essential element in providing continuous plant safety assessment, early detection of abnormal conditions, and evaluation of nuclear plant transients.
The DDL signals received in the Radiological Eniergency Assessment Center (REAC) are the same signals available to the nuclear plant personnel on-site.
The Department selects particular parameters to be transmitted to REAC from an index containing all available plant system information.
Parameters selected by the Department provide detailed information on the operating characteristics of all essential plant safety systems.
Major features of the DDL include:
o 1000 1300 parameters (signals) per reactor transmitted every two minutes.
o9 reactors currently providing data and 4 additional reactors to submit data prior to commencing operation, o Technical parameters include:
reactor power levels, reactor water
- levels, steam generator water levels, containment temperatures, engineered safety system availability, and essential pump flow rates.
o System software for displaying either current or historical multiple signals.
Features to be developed include:
o Analytical software to monitor current data and set off an alarm upon detection of abnormal conditions, o Expert System sof tware to diagnose abnormal indications and predict the probable sequence of future events faster than the accident progresses.
o Continuing software development will increase the speed and reliability of analysis, thereby further ensuring the protection of the health and safety of the citizens of Illinois.

THE RADIOACTIVE GASEOUS EFFLUENT MONITORING SYSTEM The lillnois Department of Nuclear Safety utilizes a
custom designed automated system to monitor gases routinely released by nuclear power plants.
The Radioactive Gaseous Effluent Monitoring Systems (RAGEMS) is designed to identify and quantify the radioactive components of the gaseous discharges to the environment so that appropriate emergency actions can be initiated in the event of a nuclear accident.
Although a complete system is currently installed only at the LaSalle nuclear power plant, units will be Installed at the Zion and Dresden nuclear power plants in the Fall of 1986. The Department will be installing this equipment in the rest of Illinois's nuclear power stations over the next five years.
The RAGEMS is a state of the-art, computerized system which continuously transmits data from the nuclear power plant to the Department's central computer which is located in the Radiological Emergency Assessment Center (REAC) in Springfield.
This system includes the following features:
o Dedicated computer at the power plant sites for operation and analysis, o Minimum detection level of 10 13 microCurles/ cubic centimeter.
o Maximum accident detection limit of 105 microCuries/ cubic centimeter.
o Collection and analyses of radiation in three forms: lodines, particulates, and noble gases.
o Automatic background level checks.
o Automatic check source verifications.
o Remote computer access to determine operational status and data, o Signal alarms in the event of high radiation levels or failure of a system function.
o Detection of specific isotopes based on radiation energy.
o Accelerated operation rates designed to maximize data collection during an accident.

ENVIRONMENTAL RADIATION MONITORING SYSTEM A ring of environmental radiation monitors (pressur! zed ion chambers) is installed around each reactor site that would measure a change in radiation levels resulting from a radioactive release at the reactor site.
This system serves a multitude of purposes.
It wil.1 define the existence of a radioactive release sufficiently large to impact upon the environment, as well as detect a release through an unmonitored release path. In addition, the system provides a backup capability should the effluent monitoring system be Inoperable and also reveals the presence of atmospheric conditions (wind shear) which could result in plume dispersal not following anticipated direction of travel.
The Environmental Radiation Monitoring System has the following features:
o Up to 16 monitors per site (one detector for each 22.5 degree segment) at a distance of approximately two miles from the reactor site.
o Minimum detection level of one microRoentgen per. hour.
(Natural background _levels are approximately 7 10 microRoentgens per hour.)
o Maximum detection limit is 10 Roentgens per hour (one million times normal background levels).
o Automatic transmission of radiation readings to Radiological i
Emergency Assessment Center computer system every eight minutes.
o Transmission of alarm signals to REAC in the event of high radiation levels or failure of environmental monitoring system components.
