EPIP-2 Page 2 of 6 02-24-82 1.0 Shift Supervisor Response 1.1 Obtain from Appendix 2 of this procedure a FORM EPIP-2.1,

" Report on Information Sought by Emergency Director".

1.2 Check, as appropriate to the existing situation, the blocks opposite the data desired under gaseous or liquid release.

NOTE:

If radiation monitoring system data is checked, ini-tiate EPIP ll, Estimating Release f rom Radiation Moni-toring System Data.

NOTE:

Dose estimates are going to require radiation surveys and/or sampling and therefore require time to complete.

To obtain results sooner, strike out any data not considered applicable.

1.3 Assign responsibility of the FORM EPIP-2.1 to someone in Operations and to the senior HP representative onsite.

Sign the Form following " requested by", enter the date and time. Personally ensure the assigned operator receives the Form.

1.4 Evaluate the applicability of Appendix 1, " Significance and Evaluation of Release Estimates Basad on Station System In-ventory Data", of E?IP 12. " Estimating Release from Station System Inventory Data".

EPIP-2 Page 3 of 6 02-24-82 2.0 Operations Resoonse Follow the ins: ructions for the applicable blocks as indicated on FORM EPIP-2.1.

2.1 Meteorological Data 2.1.1 Stability Class - Read directly from template attached to delta T recorder in Control Room. If delta T is not available, use alternate methods given in Appendix 1,

" Stability Class Determination", of this procedure.

2.1.2 Wind Speed - Obtain from recorder in Control Room. Use the 150 foot elevation, if not available use the 35 foot elevation, and if neither is available use an estimate from visual observations.

2.1.3 Wind Direction - Obtain from recorder in Control Room using an approximate average of the previous 15 minutes.

Use the 150 foot elevation, if not available use the 35 fnot i

elevation, and if neither available use an estimate from visual observations.

2.2 Radiation Monitoring System Data 2.2.1 Initiate EPIP ll, " Estimating Release from Radiation Monitoring System Data".

2.3 Source Evaluation Data 2.3.1 Source of Release - Identify the source as per tank number or in the case of a pipe or tube break the source supplying the pipe or tube, describe system-malfunction or any other useful information.

EPZP-2 Page 4 of 6 02-24-82 2.0 Operations Resoonse (cont.)

2.3.2 Pcssible Paths to Environs - Indicate possible paths the liquid or gases may get offsite, such as storm drains or process vent. This will aid HP in selecting sampling locations.

2.3.3 Actual or Estimated Duration of Release - Indicate the actual or estimated duration of the release to the environment in hours.

NOTE:

If the release is continuous and an estimate must be made as to when it will be terminated, the Emergency Director, Operations and Health Physics should consult one another and determine the estimated duration. If no estimate of the duration can be arrived at and the actual dose rate at the site boundary exceeds 50 mr/hr sustained for greater than 30 minutes, the Emergency Director shall declare a General Emergency.

2.3.4 Estimated Cubic Feet or Gallons Released - Indicate cubic feet or gallons of gas or liquid actually or projected to be released.

2.3.5 D11ucien Water - Indicate :he available dilution water flow rate.

2.3.6 Present Status / Remarks - Provide any information which

~

will aid HP such as indicating if the release is still in progress and if so when will it be terminated..

2.4 Forward FORM EPIP-2.1 to the assigned HP representative as soon as the above steps are complete.

EPIP-2 Page 5 of 6 02-24-82 3.0 Health Physics Response 3.1 Determine the Activity Released or Dose Estimates as reytested on FCRM EPIP 2.1 per the following steps as appropriate.

3.2 Activity Released 3.2.1 If either of the four EPIP's listed below have been initiated by Operations, release data will be generated by that EPIP, in which case proceed to step 3.2.3 below.

EPIP-4 Fuel Handling Accident EPIP-5 Steam Generator Tube Rupture EPIP-6 Main Steam Line Rupture EPIP-7 Loss of Coolant Accident 3.2.2 Select and initiate (based on available information) one or more of the following EPIP's to estimate re-lease:

EPIP-ll Radiation Monitoring System Data EPIP-12 Station System Inventory Data EPIP-13 Offsite Radiological Data 3.2.3 As release data is obtained the results are to be entered on FORM EPIP 2.2, " Gaseous Release Evaluation",

or FORM EPIP 2.3, " Liquid Release Evaluation", as appropriate. Blank forms and instructions are in Appendix 3 or 4. respectively.

3.2.4 Perform the calculations of equivalent Xe-133 and I-131 and percentage MPC as indicated on FORM EPIP 2.2 or 2.3.

3.3 Dose Estimates 3.3.1 Select and initate one or both of the following EPIP's to estimate doses.

EPIP-14 Release Data (requires step 3.2 above)

EPIP-15 Environmental Data 3.4 Enter the requested data on FORM EPIP 2.1, sign and enter the date and time and return the form to the originator (Opera-tions) or as directed.

EPZP-2 Appendix 1 Page 2 of 3 02-24-82 1.0 Fluctuation of Wind Direction Wind direction fluctuation is the number of conpass point degrees, on the wind direction recorder trace, between the two extreme gusts renaining after ignoring the two most extreme gusts (one on the left, one on the right) occuring during a 15 minute period. This difference in degrees between gusts can then be related to stability class.

2.1 Subtract the degree reading of the gust second in on the left from the degree reading of the gust second in on the right.

2.2 Obtain the stability class from the following table.

DEGREES FLUCTUATION STABILITY CLASS

> 135 A

105 to 135 B

75 to 104 C

45 to 74 D

23 to 44 E

<S G

EXAMPLE The following chart indicates for the last 15 minutes the difference between "second in" gusts is 90 degrees. The stability class would be C.
