PALISADES NUCLEAR PLANT EMERGENCY IMPLEMENTING PROCEDURE Proc No EI-6.10 Revision 5 Page 1 of 3 TITLE: OFFSITE DOSE CALCULATION - STRAIGHT LINE GAUSSIAN (MANUAL METHOD) 1.0 PERSONNEL RESPONSIBILITY The Health Physics Group Leader is responsible for the implementation of this procedure. In the absence of a Health Physics Group Leader, the Site Emergency Director or EOF Director shall delegate this responsibility.
2.0 PURPOSE This procedure implements the same equations and assumptions as used in the.
automated dose calculations. All calculations are performed manually through the use of precalculated dose factors for whole body dose rates and thyroid dose rates.
Results from this procedure can be used to check the dose calculations performed in the automated dose assessment program "Offsite."

PALISADES NUCLEAR PLANT Proc No EI-6.10 EMERGENCY IMPLEMENTING PROCEDURE Revision 5 Page 2 of 3 TITLE: OFFSITE DOSE CALCULATION - STRAIGHT LINE GAUSSIAN (MANUAL METHOD) 4.0 DEFINITIONS 4.1 CDE Committed Dose Equivalent: 50-year integrated dose to organs or tissues due to an intake at time zero.
4.2 CEDE Committed Effective Dose Equivalent: The dose committed to an individual over the next 50 years due to intake of radioactive material, weighted (by organ) to represent a risk equivalent to that of whole body exposure.
4.3 DDE Deep Dose Equivalent: Dose equivalent due to external radiation at 1 cm tissue depth.
4.4 TEDE Total Effective Dose Equivalent: Sum of deep dose equivalent due to external radiation exposure and committed effective dose equivalent due to internal exposure. When no other designator is applied to dose in units of rem, TEDE is implied.
4.5 RELEASE OF RADIOACTIVE MATERIAL Any discharge of radioactive effluent to the environment that is the result of or associated with the emergency event.
5.0 INITIAL CONDITIONS AND/OR REQUIREMENTS This procedure shall be implemented per Emergency Implementing Procedure EI-6.0, "Offsite Dose Calculation and Recommendations for Protective Actions,"
when there is a potential for, or an actual significant release of radioactive materials from the Plant site (as specified by Emergency Implementing Procedure El-i, "Emergency Classification and Actions"), and the automated dose assessment program "Offsite" is not available.

PROCEDURE 6.0 6.1 6.2 6.3 6.4 7.0 7.1 7.2 USER ALERT INFORMATION USE PROCEDURE The activities covered by this procedure may be performed from memory.
From the attached work sheets, select the one corresponding to the current Pasquill stability category (A - G).
Record the required input information in Items 1 through 6, for any applicable page of each stability class.
Complete dose calculations per instructions on the work sheet.
All completed attachments should be forwarded to the Health Physics Support Group Leader or designate for review.
ATTACHMENTS AND RECORDS ATTACHMENTS, "Manual Dose Work Sheet" RECORDS Records generated by this procedure (ie, Attachment 1) shall be filed in accordance with Palisades Administrative Procedure 10.46, "Plant Records."
SPECIAL REVIEWS The scope of this procedure does not include activities that require a 50.59 review per Palisades Administrative Procedure 10.41, "Procedure Initiation and Revision."
Therefore, changes to this procedure do not require a 50.59 review.
The scope of this procedure includes activities that require a PRC review per Palisades Administrative Procedure 10.41, "Procedure Initiation and Revision."
Therefore, changes to this procedure require a PRC review.
