" Strong" incoming solai adiation corresponds to a solar altitude greater than 60* with clear skies: " slight" incoming solar radiation corresponds to a solar
[_. altitude from 15 -35 with clear skies. Cloudiness will decrease incoming solar
\ radiation and should be considered along with solar altitude when determining solar radiatica. Incoming radiation that would be strong with clear skies can be expected to reduce to moderate with broken (5/8 to 7/8 cloud cover) middle clouds and to slight with broken low clouds. Night refers to the period from one hour before sunset to one hour after sunrise.

MINOR i Revision 1 05-28-82 EMERGENCY OFF-SITE DOSE ESTIMATIONS 1.0 GENERAL The purpose of this procedure is to permit the expeditious classification of an accident or event based on estimated off-site doses. The procedure provides a methodology to quickly estimate (1) stack release rates (source terms) and (2) off-site whole body and thyroid doses.

3.2 This procedure is to be used only for Unmediate initial dose pro-jections. The initial dose projections are to be refined using EPIP 1.3 and 1.4 once more data becomes available, i.e., meteoro-logical data, air samples, and off-site survey dose measurements.
3.3 It is recognized that the RadCon/ Waste Manager, in conjunction with the Chemistry & Health Physics Supervisor, is ultimately responsible for off-site dose assessments. However, the initial projections will normally be done by the Shift Supervisor or assigned designee for {}
purposes of classifying the event or accident because of augmentation time.

EPIP 1.8 N Page 2 4.0 INITIAL CONDITIONS .
4.1 An emergency or potential condition is anticipated to have off-site dose consequences.
4.2 A release of airborne radioactivity has occurred, or a release is anticipated, requiring a conservative estimate of the off-site dose consequences.
5.0 PROCEDURE 5.1 Calculation of Xe-133 Equivalent Release Rates (Source Terms) 5.1.1 Airborne effluents may be discharged from PBNP through the following vent stacks:
- a. Auxiliary building vent (ABVNT)
- b. Drumming area vent (DAVNT)
- c. Unit 1 containment purge vent (Cont. 1)
.. d. Unit 2 containment purge vent (Cont. 2)
_ e. Gas stripper building vent (GSBVNT)
- f. Combined air ejector decay duct (CAE)
- g. Main steam safety valves and atmospheric dump valves 5.1.2 The source terms (vent release rate in Ci/second) may be estimated by using any of the following monitoring systems.
- a. Low range operational stack monitors (designed to monitor low-level releases).
- b. Eberline RMS II radiation monitoring system (designed to mcnitor high-level releases).
- c. Contact readings using a hand-held survey meter (to be used when other monitor systems are non-operable).
5.1.3 The decision as to which moni. .ng system is to be used to estimate the source terms is supendent on the level of release and the operability of the monitor.
5.1.4 Meter readings are to be entered in the appropriate column on EPIP-34. If meter readings are "off-scale" or " inoperable," ;
enter the appropriate comment in the meter reading column on EPIP-34. A source term estimate must be made for each vent which is exhibiting readings above normal operating readings.

5.1.5 Direct contact readings using a hand-held survey meter are .
required under the following conditions: !
l
- a. Meter readings from the low range monitoring system or the RMS II system are not available.
- b. A steam generator tube rupture has occurred necessi-tating a hand-held meter reading at the main steam ;
header. i i
5.1.6 Direct contact readings using a hand-held curvey meter are ;
not to ce initiated until the following conditions are i accomplished: ;
- a. An evaluation of the radiolcgical hazards must be ccm-pleted prior to any attempt to enter the auxiliary '
building or facade to take survey readings on any stack or vent.
- b. Before the surveys are done, the proper survey meter and j the most direct and desirable route to the stack to be monitored must be chosen. i
- c. The surveys will be accomplished under the direction of
, . _ the Health Physics Supervisor. The surveys must be -
approved by the Site Manager, Duty & Call Health Physics Supervisor, and the Duty Shift Supervisor. ;
5.1.7 For surveying the main steam safety valves and atmospheric dump valves, the reading will be taken in contact with the centerline of the main steam header, three feet from the main steam line. The survey probe is to be shielded with a .;
minimum of 0.25 inches of lead on the side of the probe facing the main steam line and the containment.
5.1.8 The following data must be obtained from the Shift Supervisor in order to estimate release rates from the main steam header:
- a. Estimated flow rate of steam through the main steam header in lbs/hr.
- b. Specific volume of the steam in ft 3 /lb. At 1000 psia, specific volume of 0.486 ft3 /lb. At 500 psia, specific volume is 0.928 ft3 /lb.
Enter this data on the appropriate column in Section 3.0 of EPIP-34.
5.1.9 Sum the values on EPIP-34, Section 4.0, to determine the gross Xe-133 equivalent release rate.

EPIP 1.8 m Page 4 5.2 Whole Body Dose
- Projections 5.2.1 off-site whole body doses may be calculated at the site boundary using the following equation: -
D(REM) = X/Q x Q x Kr HR Where:
D = whole body dose rate (Rem /hr)
X/Q = atmospheric dispersion coefficient (sec/m 3)
Q = gross Xe-133 equivalent release rate (Ci/sec.)
- Kr = Dose Factor (rem-m3 )
Ci-hrs Projected off-site doses may be calculated by entering the total Xe-133 equivalent release rate calculated on EPIP-34 in the appropriate column on EPIP-35 and multiplying the variables in the equations.
7.
5.2.3 Enter .e expected exposure period in the appropriate
(
columr on EPIP-35. (A dose per hour is calculated by enter;ng an exposure period of one (1) hour.)
NOTE: THE X/Q VALUEJ LISTED ON EPIP-35 ARE ESTIMATED BASED ON CALCULATED ACCIDENT METER 0 LOGY FOR 0-2 HRS.
AS GIVEN IN THE FFDSAR. IF REAL TIME METEOROLOGICAL DATA IS AVAILABLE, X/Q VALUES CAN BE CALCULATED AS OUTLINED IN EPIP 1.4 SECTION 5.1. REFINEMENT OF THE PROJECTED OFF-SITE DOSES MAY BE ACCOMPLISHED BY SUBSTITUTING THE REAL TIME X/Q CALCULATED VALUE FOR THE ESTIMATED X/Q ON EPIP-35.
5.3 Thyroid Dose Pr)jection 5.3.1 Calculate the projected thyroid dose at the site boundary on Section 2.0 of EPIP-35 by using the following equation:
Thyroid Dose = Whole Body Dose x Conversion Factor 5.3.2 The conversion factor is dependent on the type of accident which has occurred. Conversion factors are tabulated for the following accidents:
- a. Loss of coolant accident (LOCA)
- b. Gap activity accident
- c. Fuel handling accident
- d. Steam generator tube rupture
. . :. -. -- - . .- m EPIP 1.8
-s Page 5 l
5.3.3 Choose.the appropriate type accident and calculate the thyroid dose in Section 2.0 of EPIP-35 by multiplying the ,
whole body dose calculated in Sectin 1.0 by the conversion factor.
NOTE: IF THE TYPE OF ACCIDENT IS NOT KNOWN, USE THE LOSS OF COOLANT CONVERSION FACTOR.
5.4 Classification of the Event Based on Estimated Off-Site Doses 5.4.1 The event is to be classified as a Site Emergency if the project.ed off-site doses meet any of the following criteria:
- a. Effluent monitors detect levels corresponding to any of the following doses at or beyond the site boundary:
(1) >50 mR/hr whole body for hour (2) >250 mR/hr for hour for the thyroid (3) >500 mR/hr whole body for 2 minutes (4) >2500 mR/hr to the thyroid for 2 minutes
_ b. Any of the above dose rates are projected, based on plant parameters.
5.4.2 The event is to be classified as a General Emergency if the projected off-site doses meet any of the following criteria:
- a. Effluent monitors detect levels corresponding to any of the following doses at or beyond the site boundary:
(1) 1 R/hr whole body (2) 5 R/hr thyroid
- b. Either of above dose rates are projected based on plant parameters.
5.5 Protective Action Recommendation i
5.5.1 Due to the conservative nature of the calculations in this f procedure, use EPIP 1.4 to calculate dose projections for !
protective action recommendations unless it is apparent there is no time to use EPIP 1.4. l 5.5.2 Enter dose rates and release duration estimate on EPIP-35. l If duration of release is unknown, use a release duration of 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. i t
