Subject:
Changes to the Haine Yankee Emergency Plan Gentlemen:
The State of Maine recently enacted legislation which changed the boundary of the Emergency Planning Zone (EPZ) to coincide with political boundaries.
He have modified the Maine Yankee Emergency Plan as a result of this legislation.
The changes are summarized below.
1.
Our current plume exposure EPZ consists of all, or parts of, 20 communities within about 10 miles of Maine Yankee.
(a)
Four communities (Brunswick, Bowdoinham, Damariscotta and Bristol) currently have only a small portion of their town within the EPZ.
The Maine Emergency Management Agency (MEHA) has removed these four towns from the Primary EPZ to the Secondary EPZ.
nr%8 BNBP F
9529L-JMT
1 MaineYankee United States Nuclear Regulatory Commission Page Two Attention: Mr. Hilliam T. Russell, MN-88-38 (b) Three communities (Dresden, Alna and Newcastle) currently have most of their town included in the EPZ. HEMA has extended the boundary so that each town is included in the Primary EPZ in its entirety.
2.
Eight other towns were added to the four towns to be transferred out of the plume exposure EPZ to form a new 12 town Secondary EPZ.
The Maine Yankee Emergency Plan is not affected by the Secondary EPZ.
3.
An ingestion pathway for each nuclear power plant has been defined in the State rule as a circle of 50 mile radius, centering around each plant.
Because this is consistent with current Federal regulations and guidance, no plan change is necessary.
This plan change has been extensively reviewed by company management and the Plant Operations Review Committee, and has been determined to not decrease the level of emergency preparedness for the following reasons:
1.
The plume exposure EPZ still covers an area of about 10 miles from the plant, and in fact extends some 18 miles in a southerly direction and about 13 miles in a northerly direction.
This is consistent with the prevailing wind pattern, and the probable plume pathway.
2.
The total land area in the primary EPZ has not been significantly changed.
3.
Entire towns are now included in one zone or the other.
Establishing the EPZ based upon political boundaries will improve the ability to make area specific protective action recommendations.
In addition to this plan change, numerous other changes have been made to the Emergency Plan.
These changes are summarizea and described in Attachment A and generally contain updated information (e.g., new nomograms),
organizational changes (new Maine Yankee organizational charts, changing name of the State Bureau of Civil Emergency Preparedness to the Haine Emergency Management Agency), and minor editorial changes.
These changes have also been reviewed by company management and the Plant Operations Review Committee.
It has been determined that these changes do not decrease the effectiveness of the Emergency Plan.

t 4.3 Site Area Emergency Actual or likely major failures of plant functions needed for protection of the public constitute a site emergency.
(This classification would be assigned even though the affected plant function may not be required at the time.)
Potential significant releases of radioactive material could be associated with this class of event.
Protective action guides could be exceeded in a limited area offsite.
4.4 General Emergency Actual or imminent substantial core degradation or melting with potential for lots of containment integrity constitutes a general emergency.
Potential major releases of radioactive material could be associated with this class of accident.
Protective action guides could be exceeded over a substantial area offsite.
Table 4-1 contains examples of emergency action levels for each class of emergency condition.
The implementing procedure entitled "Declaration and Categorization of Emergency Condition" includes
]
a table of EAls which contain measurable / observable indications of plant systems whtte applicable.
Provisions for dealing with onsite occupational injury or overexposure to radiation are also covered in this plan.
4.2 03-17-88
5 Ooerations consists of activities performed or directed by licensed reactor op.erators who control the operation of plant fluid, instrumentation, and electrical systems and equipment.
These activities take place in or are directed from the control room under the supervision of a senior licensed operator.
Operations is supported by a pool of plant staff experienced in operations or maintenance available in the Operations Support
]
Center to aid in nonroutine operation of plant systems and components and repairs to maintain or restore necessary plant functions.
Technical succort consists of activities performed by or under the direction of plant engineering and technical staff members and others to analyze and evaluate the status and performance of reactor and plant systems and to develop and review procedure revisions which take account of plant conditions.
These activities, which take place primarily in the technical support center, are intended to support the activities of operations and emergency coordination and to keep management informed.
In addition, technical support relieves the control room of the burden of nonessential communications.
Technical support is provided by supervisory personnel drawn from the plant staff, the technical support department staff and offsite technical expertise.
Technical support is directed by the Vice President / Hanager of Operations, or his designated alternate in the operating organization.'
5.4 03-17-88
The Federal Government may also be called upon for assistance through the Federal Radiological Emergency Response Plan (FRERP).
Requests for assistance can be made directly from the appropriate Federal agency (e.g., NRC, DOE) identified in the FRERP. Table 5-2 shows the l
assignment of responsibilities for major emergency response elements.
5.4 Coordination with Participating Government Agencies i
The Emergency Coordinator is responsible for coordinating Maine Yankee j
activities with government agencies participating in offsite radiation monitoring, dose projection, and determination of protective actions for the public.
The Emergency Coordinator receives results of offsite dose monitoring from the Maine Yankee field monitoring teams and relays these results together with conclusions drawn from them to the Division of Health Engineering (OHE) via the data hotilne to DHE's operations base at the
]
Maine Emergency Management Agency (MEMA) headquarters in Augusta.
This
]
coordination is enhanced by the presence of a Division of Health Engineering liaison officer in the EOF and further by utilization of DHE personnel in field monitoring operations.
Dose projections and advice concerning protective actions for the public are relayed by the Emergency Coordinator in a similar manner.
5.11 03-17-88
In the event that the presence of a Maine Yankee representative at HEMA headquarters in Augusta is requested, the Emergency Coordinator
]
is authorized to dispatch a ;epresentative to the State EOC, if available.
Maine Yankee has also trained several employees to assist the offsite community emergency response organizations in the use of personnel dosimetry and exposure control. At the Alert or higher classification, j
the Offsite Dosimetry Assistants (00A) would be dispatched, if needed, to local emergency operations centers (EOCs) located downwind from the plant.
They will assist in issuing personnel dosimetry to emergency workers and maintaining exposure control records if trained local personnel are unavailable to establish this function.
If the
~
00A's assistance is not needed, he will proceed to another local EOC as directed by the Emergency Coordinator.
5.12 03-17-88
1.
Unusual Event The basic shift complement is able to deal with unusual event conditions. Additional plant personnel will respond at the discretion of the Plant Shift Superintendent.
e In an unusual event condition, the following occur:
Emergency condition declared by Plant Manager or designated alternate (Plant Shift Superintendent on back shifts and weekends).
On-duty operating and security personnel respond.
State Police notified by control room.
In turn, State Police notify the Governor, Maine Emergency Management Agency, Health
]
Engineering and the Lincoln County Sheriff.
On-duty NSE notified and reports to control room. He notifies NRC and the Maine Yankee Nuclear Support Division.
On-call Supervisor notified.
He provides for notification of the plant management, emergency coordination, technical support, operating support, and offsite dosimetry assistants as appropriate then reports to site.
(The On-call Supervisor may elect not to come to the site in unusual event conditions which have been or will be quickly terminated.
This election is made after consultation with the Plant Shift Superintendent and NSE).
6.4 03-17-88
- Tone Alert Transmitter.
In the event of an emergency, NOAA transmitter j
and the tone alert system operated by Maine Yankee transmits a signal which turns on in-house monitors in the EPZ which can then receive emergency messages.
Individuals who so desire may purchase their own monitors.
The initial messages to be broadcast are presented in Volume I.
The design objective of the PEAS is to provide the capability to alert the public within the plume exposure emergency planning zone within 15 minutes of notification of the State Police that an emergency condition exists.
The State Police will be notified of the existence of an emergency condition within 15 minutes of its declaration by site personnel, Emeraency Communications There are four separate dedicated telephone (hotline) systems.
These circuits automatically ring the other location (s) on the circuit when the telephone handset is picked up.
The first, (the "notification hotline"), connects the Maine Yankee control room with the primary 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> notification point, the Maine State Police Headquarters in Augusta.
The second, (the "data hotline") connects the Maine Yankee EOF and Control Room with the Maine Emergency Management Agency headquarters
]
in Augusta.
This link ensures reliable communication of radiological, meteorological and other technical data.
6.11 03-17-88
The third, (the "Governor's hotline"), connects the Haine Yankee EOF with the MEM3 Director's office in the State EOC in Augusta.
This
]
assures a dedicated communications line for use by State, utility, and Federal top executives.
The fourth, (the "command and control hotline") connects the Maine Emergency Management Agency EOC in Augusta with the Lincoln and
]
j Sagadahoc County EOCs and the EOCs of the twenty local communities within the plume exposure emergency planning zone.
This link ensures reliable command and control communications between emergency operations facilities.
6.3 Assessment Actions Assessment actions are those actions taken to obtain and evaluate information necessary to assess the nature and magnitude of an emergency condition to determine the appropriate response measures (e.g. plant monitoring instrument and equipment status indications, field radiological contamination or level readings, reports from others, calculations and projections based upon compiled information).
l These actions are described as follows:
6.3.1 Plant System and Equipment Assessment Operations personnel and the NSE will review plant systems parameters to determine the status of the reactor or other 6.12 03-17-88
The population distribution around Maine Yankee for each sector j
out to,10 miles and from 0 to 50 miles is shown in Figures 6-10
]
and 6-11, respectively.
6.6 Aid to Affected Personnel This section describes the measures to be used to provide necessary assistance to persons injured or exposed to radiation and radicactive material.
6.6.1 Emergency Personnel Exposure Emergency response personnel who do not possess personnel dosimetry at the time they respond to an emergency are issued dosimetry at the EOF.
The procedure entitled "Emergency Radiation Exposure Control" provides exposure guidance and personnel dosimetry requirements during emergency conditions.
Exposure of emergency personnel to higher than normally accepted levels of radiation in order to retrieve injured persons or to perform necessary corrective actions will be in accordance with NCRP Report 39, "Basic Radiation Protection Criteria" and EPA Lifesaving Activity Protective Action Guide.
Such exposure requires express approval of the Emergency Coordinator, or higher management.
l In circumstances where it is necessary to enter a hazardous area to protect facilities, eliminate further release of radioactive material or to control fires, the following objectives apply:
6.24 03-17-88
\\
Yankee environmental laboratory (Westboro, MA) complete environmental laboratory facilities including radiochemical and multichann91 analysis capability for environmental media and personnel TLD dosimetry.
See Appendix I for details.
Yankee mobile environmental laboratory mobile multichannel analysis capability for in situ ground measurements and high pressure ionization chamber capability for dose rate determination.
State of Haine environmental laboratory see Volume I Yankee mobile dosimetry unit (unh r development) mobile TLD personnel dosimetry and body burden counting. Maine Yankee has an onsite body burden counter.
7.3.3 Offsite Facilities and Equipment Hithin about one-half mile from the plant site, the company owns two buildings and large acreage (the Eaton Farm property) which can be used for administrative and logistical support by an expanded support organization, if required.
The Newcastle District Office of Central Maine Power Company, located on U.S. Route 1 about 5 miles northeast of the plant site, has been designated as the offsite assembly area if immediate site evacuation is necessary.
This determination
]
will be made by the Emergency Coordinator or Plant Manager.

numerous small rivers and streams along with a number of lakes and ponds.
Several small urban or village concentrations are found throughout the EPZ with one city located on the western fringes of the zone.
The principal highway serving the EPZ is Interstate 95/U.S. Route 1.
Numerous state and local roads running from the inland and peninsula areas intersect with the I-95/U.S. Route 1 corridor.
There are sixteen (16) communities whose geographic boundaries fall
]
completely within the primary EPZ.
Their location relative to the 1, 2, 5,

Evacuation time estimates were considered in defining the plume exposure EPZ and the development of the PEAS.
The emergency alerting system has been designed to ensure that the most critical notification areas (those close to the site and those which exhibit both high seasonal population and unique egress features in coincidence) receive heavy emphasis on early and complete public notification.
1 The EPZ extends considerably beyond the suggested 10 mile radius in some directions to accomodate political boundaries.
It extends 18 miles in a
]
southerly direction to include the peninsular areas for which evacuation
]
would necessitate travel toward the plant into the 10 mile radius area, thus potentially adding to the egress network traffic load.

O Vehicles equipped with the mobile systems must be those expected to be within the region,most of the time.
Fire department, public works, and other i
emergency response vehicles are the primary candidates. Others would include Fire Chief and Deputy Fire Chief cars, town constable, and local
)
emergency management personnel.
State law prohibits the equipping of
]
private vehicles with sirens.
Thus, all vehicles so equipped must have a distinct public response requirement and owners of private vehicles must serve in an official fire, police, or rescue capacity. All radio frequencies will be available to the Sheriff Departments and towns in order to broadcast periodic situation updates and for general coordination.
The mobile siren sound would be a distinctive sound reserved only for regional emergencies, similar to that produced by the fixed sirens, recognizable to the public and requiring the public to tune EBS or NHS.
An obvious advantage of a system of mobile sirens and public address units is that the entire regional population can be reached by both siren and voice instructions. A mobile system provides reliability, flexibility, security, and back-up.
Distinctive sounds which can be known to re'idents, with optional voice projection, would mitigate the concern for transients not having proper notification.
Mobile systems also have an advantage in overcoming ambient noise such as from traffic on heavily traveled roads like Route 1.
i In the 1978 Kennebunkport tidal wave evacuation, town officials cited the applicability of the mobile siren and public address system.
Town records III.13 03-17-88
In the event of an emergency condition at Maine Yankee, the State Police would inform the NHS Portland center via telephone. NHS would respond, after proper verification, by activating the tone alert and then broadcasting a prerecorded emergency notification message worded specifically for the level of emergency declared.
Follow up messages, to be provided by the Maine Emergency Management
]
Agency from their Augusta EOC over teletype, will be recorded by a NHS
]
broadcaster and then aired.
The NOAA tone alert system is a backup to the fixed sirens and notifier team.
Those in the area who feel the need of this type of alert system either due to special circumstances or apprehensiveness about the plant can obtain in home monitors locally. Maine Yankee provided, on a one time basis, twenty monitors to MEMA who distributed them to schools, hospitals and nursing
]
homes in the EPZ.
Hotlines Two multipoint private telephone systems complement the PEAS.
The first, the data hotline, connects the Maine Yankee EOF and with the Control Room with the MEMA (State EOC) in Augusta.
Its purpose is to allow
]
exchange of data and information important to protective actions and dose mcnitoring.
The second, the command and control hotline, links together the State EOC, the EOC's of Lincoln and Sagadahoc Counties, and the E0C's each of the
]
III.25 03-17-88
1 twent/ comunities in the EPZ.
Each can comunicate with the others.
Its purposes are to al. low advance notice to local officials from the Governor of upcoming public announcements, to provide for status reports, coordination of emergency cperations, requests for aid, and generally for keeping community leaders carrying out their plans in touch with county and State officials.
VI MEETING THE DESIGN OBJECTIVES The PEAS design objectives were stated in section II.
The following discussion indicates how the PEAS meets each design objective:
Obiettive 1 - Meet Reaulatory Reauirements (See introduction)
Objective 2 - Comoatible with State and Local Plans.
The system has been designed in close cooperation with MEMA and each
]
of the comunities within the EPZ.
Specific details pertaining to the PEAS elements in each community were derived from information taken directly from the local plans and obtained in detailed discussions with 1
town officials.
Obiective 3 - Reflect Coanents from Towns Many of the communities comented on the proposed system subsequent to a regional meeting to discuss the PEAS.
Some comunities called strongly for fixed sirens, some for mobile sirens.
To the maximum extent possible, the
.coments of each town were accomodated, expecially when special circumsta1ces existed. Where strict conformance with town comments were not feasible, alternatives were explored and agreement was reached.

MAINE YANKEE EMERGENCY OFF-SITE DOSE PROJECTION NOMOGRAMS In the event of a serious accident at Maine Yankee, radioactive fission products may be released to the environment through three major release pathways; the Primary Vent Stack (PVS), the Main Steam Line (HSL), and/or the containment via leakage through penetrations..Each of these systems contains a radiation monitor capable of detecting relcase conditions which range from marginally detectable with conventional survey equipment at 1/2 mile off-site, to the most severe accident condition that has been postulated.
If evidence of any of these release conditions exists, then an estimate of the activity release rate and the corresponding off-site dose rate is available for information in discussions with state authorities. Since this information is of interest promptly following the onset of an accident, then an expeditious method for determining the release conditions is desired which; 1) accounts for changes in the source term photon spectrum as it decays with time, and 2) utilizes the actual meteorological conditions that are present at the site.
A method has been developed which meets these criteria by presenting all of the necessary information in the form of nomograms.
Each release path has
]
two nomograms; one to determine the total noble gas release rate and
)
off-site whole body dose rate 1/2 mile from the release point, and one
]
to determine the I-131 dose equivalent release rate and the associated
)
infant thyroid dose rate at 1/2 mile.
The following discussions provide
]
a brief explanation of each nomogram used for whole body dose projections.
The mechanics of the nomogram use are not detailed in the following I
discussion since it is felt that they are self-explanatory.

i IV.2 03-17-88 I
Containment Leakacte Nomoaram:
The Maine Yankee Emergency Containment Leakage Nomogram are based on
]
fission product noble gasses uniformly mixed within the containment free air volume and being released directly to the atmosphere as a ground level release 2
at a rate of 0.1% per day at a containment pressure of 55 lb/in.
The noble gas concentration within the containment is estimated by using the in-containment radiation monitor (which is a General Atomic ionization chamber 0
7 with a range of 10 to 10 R/hr) response in conjunction with the Release Rate Function, J(t) uti cm-3 The in-containment radiation monitor is a R hr-I redundant system located on the south wall of the pressurizer cubicle so as to view a large fraction of the containment free air volume.
The Release Rate Function, J(t), is a conversion factor which is used to determine the containment total noble gas concentration at a decay time (or time after shutdown), t, of an initial core mixture of noble gas fission products.
This factor, as shown in the lower lef t hand block of the nomogram, was calculated with the aid of Source Term and Radiation Shielding Computer Codes.
I-131 Dose Equivalent Release rate function, J(t)g, used in
]
the Thyroid Dose Nomogram is obtained by the use of a predetermined, 3
pathway specific, iodine to noble gas ratio.
This ratio allows for
]
the direct computation of curies of I-131 0.E. release per curie of
]
total noble gas released.
]
The Off-Site Dose Rate at 1/2 mile is determined from the Off-Site Dose Rate Function, J(t)/f(t), the In-Containment Radiation Honitor Response, the Atmospheric Stability Class (Pasquill), and the prevailing wind speed.
The Off-Site Dose Rate Function, is the ratio of the Release Rate function, J(t), to the value of f(t), each evaluated at time t after shutdown.
1he parameter f(t) is the effective infinite cloud whole body dose conversion factor for a fission product mixture at a decay time t.
Each of these parameters is evaluated for a core mixture of noble gas fission products.
IV.3 03-17-88
The Atmospheric Stability Class, as determined from the delta temperatura indication at the' meteorological terminal, is used to determine the appropriate Gamma Dose Diffusion Factor in conjunction with the wind speed.
The factor accounts for the finite plume size for each stability class at 1/2 mile from the release location.
These values are sector average and have been pre-determined with an assumed gamma energy of 0.5 MeV.
The off-site dose rate function for iodine, J(t)y
- DCF,
3 y
used in the Thyroid Dose Nomogram is straight forward since the release
]
of iodine is expressed in I-131 dose equivalent.
The dose conversion
]
factor used is for the thyroid dose to an infant from inhalation of
]
I-131. Because the release is expressed as I-131 0.E., the iodine dose
]
conversion factor is not time dependent.
Plume centerline concentration
]
diffusion factors are used in the determination of thyroid dose.
3 Stack Release Nomoaram These nomograms are based upon a high level of radioactive
]
fission products being released through the primary vent stack such that the High Range Noble Gas Stack monitor response increases over the baseline indication.
This monitor is a Victoreen 847-8 ionization chamber with a range 7
1 of 0.1 to 10 MR/hr placed in the well of an 18 inch steel marinelli beaker I
with 8 inches of lead surrounding the detector and beaker.
The stack exit gas continuously passes through this beaker from the exit line of the "normal range" stack effluent monitoring system. As in the case of the in-containment monitor discussed above, Release Rate Functions, J(t), and Off-Site Dose Rate Functions, J(t)/f(t), have been developed for this detector / source geometry using radiation shielding and source term computer codes.
For this nomogram, however, a second fission product noble gas mixture has been considered in addition to the "core mixture", that is the "coolant equilibrium" noble gas mixture.
This coolant mix is to be used in the event where core damage has not been incurred by an event, and the source of the release is only from the reactor coolant system inventory.
The Gamma Diffusion Factors for this nomogram are sector average values at 1/2 mile for an elevated release (53 meters), and L for an average gamma energy of 1.0 MeV.

Iodine release rates and subsequent thyroid dose rates are
]
projected using the Thyroid Dose Nomogram for the Stack release.
]
The same methodology is used as discussed under the Containment 1
Leakage Nomograms.
3 l
Main Steam Line Release Nomoaram These nomograms are based on a large concentration of fission product noble gases present in one of the three Main Steam Lines and being released via the Atmospheric Steam Dump, (ASD) (operated at full capacity for 1 steamline), or the set of Main Steam Line Safety Valves. High concentrations of fission product noble gases are detected by the Main Steam Line Radiation Monitors, which are Victoreen 847-B ionization chambers placed adjacent to each Steam Line located in the Valve Room.
The Release Rate Functions,
]
J(t), and the Off-Site Dose Rate functions, J(t)/f(t) are based on the 3
fission product mixtures expected from a Steam Generator Tube Rupture
]
accident.
This release is considered a ground level release in which the pre-calculated gamma diffusion factors are the same as that for the j
Containment Leakage Nomogram.
The proper Release Rate or Off-Site Dose Rate axis is chosen based on the appropriate release pathway as determined from the control room.
These axes assume that if a higher pressure valve has lifted that the lower valves are also contributing their full capacity to the release condition.
Iodine release rates and subsequent thyroid dose rates are
]
projected using the Thyroid Dose Nomogram for the Main Steam Line
]
Release.
The same methodology is used as discussed under the Containment
]
Leakage Nomograms.
