h- d. Main Steam Line Break The Main Steam Line Break will not give a continuing release rate but will empty the SG in less than two minutes (assuming feedwater is stopped). Subsequently, the only releases will be the amount of primary to secondary leakage. The Zugineering Technical Assessment Group must be consulted for a flow rate for the primary to secondary leakage rate.

For Main Steam Line Break:

1) Record the Main Steam Line Monitor reading prior to the break (conversion factor will not be valid after break).

2) Use 5.1 E3 cfm for flow rate.

3) Use 2 min (1/30 hour) for release duration.

4) After initial release (2 min), request Engineering Technical Assessment Group to provide flow rate of release due to

,, primary-to-secondary release and calculate release based on I _

reactor coolant concentration (let-down monitor, grab-samples, etc.).

r' 1.0 PURPOSE

(-

This attachment provides a method for calculating the projected dose

rate at the EAB. It is based upon nine accidents that were analyzed in the FSAR.

NOTE This technique should be used only when there is no plant or field monitoring data available. It should be used only as a first approximation and

! quickly replaced as plant and/or field data becomes available.

2.0 PROCEDURE i

g 2.1 From the nine accidents identified on the worksheet, select the type of E accident based on the actual occurrences (Attachment 7.6, page 3 FSAR 1 Accident Assumptions, provides background information for this selection

, and is used for additional data).

2.2 Using the Short Form worksheet on page 20 of this procedure, develop the  !

j I/Q at the Exclusion Area Boundary (EAB) and record in the appropriate location on the FSAR Accidents worksheet. I/Q = Iu/Q from Column 8 divided by wind speed from Column 3 on worksheet.

i 2.3 Multiply the I/Q.by the appropriate dose factor (includes correction factor) for that accident (whole body and/or child thyroid) to obtain the projected dose at the EAB and record.

1 2.4 Additional worksheets are to be used to calculate doses at other i

distances using the appropriate dispersion (I/Q) factors.

FSAR ACCIDENT ASSUMPTIONS  !

t This attachment provides the basic assumptions and radiological consequences (Design Basis) for the incidents that are not expected to occur but are postulated because their consequences would include the potential for the release of significant amounts of radioactive material. This attachment is to be used when instrumentation used for assessment is off-scale or inoperable.

Identify the type of incident which has occurred from the nine incidents defined in this attachment. If no identification is possible, use the most restrictive accident which cannot be reasonably excluded.

The information given below should be used in ratioing and adjusting assumed FSAR values with any known actual values in the event of an -

incident at Waterford 3 Steam Electric Station.

IDENTIFICATION AND RADIOLOGICAL CONSEQUENCE ASSUMPTIONS

1. Main Steam Line Break g

I- m This incident is defined with a simultaneous loss of off-site power.

Steam is vented directly to the atmosphere.

2.- Inadvertent Steam Dump For an inadvertent opening of steam generator atmospheric dump valve with a primary-to-secondary leak rate of one (1) gallon-per-einute and with a concurrent single failure of an active component and loss of off-site power, the activity released from the Steam Generators is immediately vented to the atmosphere.

i 3. Control Element Assembly (CEA) Ejection Accident This accident assumes a loss of off-site power at the time of turbine trip and a 6.5 (uci/g I-131) dose equivalent for the primary system (activity in the coolant systems prior to the accident).

4. Primary Sample or Letdown Line Breal-For primary sample or letdown line break incidents, a two-inch schedule 160 pipe is analyzed. A rupture outside the containment causes a release to the Reactor Auxiliary Building (RAB).

.~ v _

f 8 FSAR ACCIDENT ASSUMPTIONS CONT'D.

i

\ 5. Steam Generator Tube Rupture (SGTR)

This accident assumes a loss of off-site power and a double-ended severance of a single Steam Generator tube and allosa transport of reactor coolant into the main steam system. Release is via the Steam Generator safety valves and atmospheric dumps.

6. Loss of Coolant Accident (LOCA)

A LOCA provides a release path to the environment via containment leakage pathways.

7. Radioactive Waste Gas System Leak or Failure This incident assumes an unexpected and uncontrolled release to the 1 atmosphere of radioactive xenon and krypton fission gases.

8. Liquid Waste System Leak A Liquid Waste System leak or failure results in a release to the f"

atmosphere and a release of all liquids in the Boron Management System Q; (BMS) and Waste Management System (WMS) to the Reactor Auxiliary (RAB). Off-site doses will occur as a consequence of released noble l gases and iodines assumed to volatilize from the spilled liquids.

9. Puel Handling Accident A fuel handling accident is the most restrictive accident defined in the FSAR.

4 2.2 Isopleth Overlays are provided for each stability class. The isopleths are used to define plume dimensions as well as approximate relative concentrations (1/Qs) and dose rates _within the plume.

t 2.2.1 Select the appropriate Emergency Planning Isopleth Overlay based on stability class. Align the center axis of the overlay with the centerpoint (plant) of the Emergency Planning map. Orient the overlay 3

such that the projection occurs in the downwind direction (e.g. , wind j direction recorded as from 270 degrees West should orient the overlay j in a 90 degrees East direction).

1 2.2.2 Each isopleth line on the overlay defines the points where the i relative concentration (I/Q) or dose rate has decreased to a specified fraction of the centerline value. The specified fractions for each

, isopleth line are given on the overlay.

l (7 2.2.3 Estimates of plume travel times for various downwind distances and

'~ a wind speeds are presented in Table 1 (page 73 of this procedure). 1 2.2.4 Plume widths at different downwind distances for various fractions of '

the centerline I/Q (or dose rate) are expressed numerically in Table 2 j

(pages 74 to 80 of this procedure) for each stability class. The data in Table 1 provide the bases for the isopleth overlays described above.

METEOROLOGICAL DATA AND CALCULATION OF ATMOSPHERIC DISPERSION FACTORS CONT'D.

i NOTE Very stable conditions (F or G stability class) along with low wind speeds and frequently varying wind directions may result in an

- extremely narrow, meandering plume. Locating this plume with fixed field monitoring points may not be possible. Therefore it may be appropriate to obtain field monitor 4ng data from non-fixed monitoring locations. Once the plume has been located it would be appropriate

~

to use the steps described below to datermine a I/Q value to use in calculating dose projections.

2.3 In the event the Computerized Dose Assessment (Back-up) Method fails or a I/Q value is required for a non-fixed field monitcring location, the following manual method has been developed. The mantal method utilizes the Zu/Q Grid Overlay, the Atmospheric Dispersion Factor Worksheet (Figure 1 on page 95 of this procedure), and the ZuQ values given on Table 3 (pages 81 to 94 of this procedure). The I/Q values determined can be used for calculating dose projectf.ons in procedure Attachments 7.4 (Dose Projections Based on Field Monitoring Data) - 7.5 (Dose Projections Based on Known Isotopic Release Data), and 7.6 (Dose Projections Based on FSAR Accident Data).

2.3.1 Align the center axis of the Ku/Q Grid Overlay with the centerpoint (plant) of the Emergency Planning map. Orient the overlay such that the projection occurs in the downwind direction (e.g., vind direction recorded as from 270 degrees West should orient the overlay in a 90 degree East dirsction).

2.3.2 Record the time, sampling location, stability class, and 10 meter (31 foot) level wind speed (in sph) on the worksheet.

2.3.3 Using the Iu/Q Grid Overlay, determine the coordinates (downwind and off center dir.tances) of the location of interest with respect to the centerline and off centerline axes. The coordinates are defined by rounding to the lower 0.5 mile increment on each axis. Record these values on the worksheet.

2.3.4 Using Table 3 (pages 81 to 94 of this procedure) determine the Iu/Q value corresponding to the downwind and off center distances determined in step 2.3.3 above for the appropriate stability class.

Record this value on the worksheet.

2.3.5 The I/Q value is determined by dividing the Iu/Q value determined in step 2.3.4 by the 10 meter (33 foot) level windspeed recorded in step 2.3.2. Record this value on the worksheet.

, 2.3.6 Repeat steps 2.3.2 through 2.3.5 for all locations of interest.

Realign the isopleth grid according to changes in wind direction as per step 2.3.1.

[ 1.0 PURPOSE This attachment provides a method of using portable radiation survey meter data to project noble gas release rates for use in situations when the installed radiation monitors are inoperable. Once obtained, the release rate data can be used with Attachment 7.3, Dose Projections based on Plant Monitoring Data.

2.0 PROCEDURE 2.1 Have Health Physics personnel obtain survey meter readings on the Y

, 3 appropriate release point piping. Readinas should be taken ci 9 at  ?

- 2. 2 Based on information communicated by the Emergency Coordinator, determine whether major fuel failure or <1% fuel failure is appropriate to the situation.

\~

2.3 Based upon the selected fuel failure condition, record the dose rate measured bQealth Physics on the Survey Heter Release Rate Worksheet (page 97A of this procedure). Note that the reading should be recorded - d in units of mR/hr and ensure that the data is recorded in 2: ".t N

2.4 Record the appropriate flow rate in CFM on the Worksheet. See Attachment 7.3. Table 1 (pages 49 and 50 of this procedure) to determine CFM to use if a flow rate is not available.

2.5 Multiply the survey meter reading times the conversion factor times the l flow rate. The product is the noble gas release rate in Ci/sec. Record I

on the Worksheet.

2.6 This release rate is the same as the Column D release rate found on the worksheets in Attachment 7.3. The release rate determined via this attachment may then be used with Attachment 7.3 to perform dose

( proj ections.
