SUMMARY

Number: PMP-2080-EPP-108 - - _ Revision: 5 Change: 0

Title:

Initial Dose Assessment Section or Step Change/Reason For Change Entire Change: This revision implements changes to an emergency plan implementing procedure, therefore a 50.59 review is not required.

Reason: This process is wholly controlled under 10 CFR 50.54(q) and plant procedure RMA-2080-EPA-008, Emergency Plan Management.

Section 2 Change: Added acronyms and meanings for SM and TSC.

Reason: These acronyms are used in this revision.

Step 3.2 Change: Added clarification for approval authority for EMD-32 forms after TSC activation and prior to EOF activation.

Reason: Not previously addressed in this procedure.

Step 4.2 Change: Added statement that meteorological data may be obtained from the Midas Data link on the Operations Department web page.

Reason: Provide for alternate MIDAS data location.

Step 4.5 Change: Added the lower range radiation monitoring reading to the Cladding Damage coolant type.

Reason: Lower limit was not previously specified.

Step 4.10 and Change: Allowed for submittal/approval of EMLD-32 forms by the SM.

. Reason: Allows for SM approval of forms after the TSC has been activated (under SEC direction), but prior to EOF activation. , Change: Added statement that meteorological data may be obtained Step 1.1.1 from the Midas Data link on the Operations Department web page. -

Reason: Provide for alternate MIDAS data location.

Information PMP-2080-1EPP-168 Rev. 5 Paoe 2 of 9 Initial Dose Assessment 1 PURPOSE AND SCOPE 1.1 This procedure provides instructions for performing initial dose assessment for releases of radioactive material from the plant.

1.2 Use of this procedure should be limited to actual emergencies and emergency drills.

2 - DEFINITIONS AND ABBREVIATIONS Term Meaning DAP Dose Assessment Computer Program EMD-32a State of Michigan Emergency Notification form (Nuclear Plant Event Notification)

EMD-32b State of Michigan Technical Notification form (Nuclear Plant Event Technical Data)

PAR Protective Action Recommendation PPC Plant Process Computer RMS Radiation Monitoring System SEC Site Emergency Coordinator SM Shift Manager TSC Technical Support Center 3 RESPONSIBILITIES 3.1 The SEC is responsible for the implementation of this procedure.

3.2 The SEC must review and approve all EMD-32a and EMD-32b forms prior to transmission to Berrien County or the State of Michigan. This is a non-delegable responsibility. Upon TSC activation, the SEC may direct the control room (Shift Manager) to retain notification duties in accordance with the Emergency Plan and RMT-2080-TSC-001, Activation and Operation of the TSC, until relieved of this

-function by the Emergency Operations Facility.

Information -Tl PMP-2080-EPP-108 Rev. 5 Page 3 of 9 Initial Dose Assessment 4 DETAILS NOTE: DAP contains extensive on line help. Help for any particular subject may be obtained by placing the mouse over the object in question. If help is available it will appear at the bottom of the screen.

NOTE: Dose assessment projections may only be performed using the DAP. IF projected doses are NOT available and a PAR is necessary, THEN use the default PAR in PMP-2080-EPP-100.

4.1 Determine which forms are required.

4.1.1 EMD-32a, Nuclear Plant Event Notification.

. Is only transmitted to the State/County within 15 minutes of a change to the emergency classification or PAR.

- Must include an EMD-32b, Nuclear Plant Event Technical Data Form if the emergency classification is General Emergency and the PAR is based on dose calculations.

4.1.2 EMD-32b, Nuclear Plant Event Technical Data Form.

. Required to be transmitted to the State/County within 30-minute intervals of the last EMD-32b or EMD-32a form.

4.2 Obtain meteorological data from the PPC or from the intranet on the Operations Department web page using the "Midas Data" link. Attachment 1, Meteorological Data, contains additional sources of meteorological data and Attachment 2, Pasquill Category, provides for Pasquill Category (Stability Class) determinations.

4.6.1 An actual release is occurring when any of the following are true:

  • Valid indication on release point radiation monitoring system channels are present that are associated with a classified event,

-OR-

  • Measured off-site radiation readings indicate a release is in progress,

-OR-

. Indications exist that an unmonitored release may be occurring.

4.6.2 A potential release exists if calculated data is postulated based on present plant conditions (i.e., Containment Loss of Coolant Accident (LOCA)).

IF releases are occurring from multiple points, THEN use the longest projected duration.

4.8 Enter the data into the Dose Assessment Program.

NOTE: The classifications may change based on the results of the assessment being run and must be updated accordingly prior to submitting the EMD-32a or EMD-32b forms for transmittal to the state or county.

4.9 IF necessary, THEN update the current classification and Initiating Conditions on the EMD-32a and EMD-32b.
