PACIFIC GAS AND ELECTRIC COMPANY NUMBER EP R-2 NUCLEAR POWER GENERATION REVISION 22 DIABLO CANYON POWER PLANT PAGE 1 OF 5 EMERGENCY PLAN IMPLEMENTING PROCEDURE UNITS TITLE: Release of Airborne Radioactive Materials Initial AND Assessment 1 N 2 03/18/04 EFFECTIVE DATE PROCEDURE CLASSIFICATION: QUALITY RELATED

1. SCOPE 1.1 This procedure describes the steps to be taken by on-shift personnel to initially evaluate the off-site consequences of an accidental airborne release that may result in Emergency Plan Activation.

1.2 It does not describe the operation of the plant equipment necessary to terminate or minimize the release. This latter subject is covered in the appropriate E, ECA, and FR series Emergency Procedures for the particular release mechanism.

CAUTION: Revisions to this procedure require the PPC display be updated (Reference A0595224).

2. DISCUSSION 2.1 An accidental airborne release of radioactive materials that may result in site boundary dose rates in excess of the limits specified in the EP G-I shall require a prompt initial assessment by the operating staff. This initial release rate and dose assessment is performed using either the Plant Process Computer (PPC) program "EPR2," or manually using Section 7 of this procedure.

2.2 This procedure shall only be used by Control Room personnel to perform initial accident dose assessments. This procedure shall not be used to evaluate compliance with Technical Specification limits during planned effluent releases conducted as part of normal plant operations. The methodology contained in this procedure is intended to provide a rapid and conservative calculation of the projected off-site doses due to an accidental release of airborne radioactive materials. More advanced methodologies are contained in procedures EP RB-9 and EP RB-I I or the appropriate chemistry procedures.

3. DEFINITIONS 3.1 Accidental Release - A release of radioactive material unrelated to any planned effluent release evolutions.

3.2 Committed Dose Equivalent (CDE) - The dose to the organs or tissues that would be received from an intake of radioactive material by an individual during the 50 years following the intake.

3.3 Committed Effective Dose Equivalent (CEDE) - The sum of the products of the weighting factors applicable to each of the body organs or tissues that are irradiated and the CDE to these organs or tissues.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER EP R-2 DIABLO CANYON POWER PLANT REVISION 22 PAGE 2 OF 5 TITLE: Release of Airborne Radioactive Materials Initial UNITS I AND 2 Assessment 3.4 Deep Dose Equivalent (DDE) - Dose associated with exposure of the whole body (depth of I cm).

3.5 Total Effective Dose Equivalent (TEDE) - The sum of the DDE (for external exposure) and CEDE (for internal exposure).

3.6 TEDE Rate - The time rate of change of Total Effective Dose Equivalent as a function of immersion and inhalation exposure time.

3.7 Thyroid CDE Rate - The time rate of change of Thyroid Committed Dose Equivalent as a function of immersion and inhalation exposure time.

4. RESPONSIBILITIES 4.1 Emergency Evaluation Coordinator (EEC) is responsible for performing an initial assessment of an airborne radiological release when directed by the ISEC.

4.2 Interim Site Emergencv Coordinator (ISEC) is responsible for determining when an assessment is needed and directing the EEC to implement this procedure based on emergency evaluation priorities.

5. PREREQUISITES 5.1 Unified Dose Assessment Center (UDAC) is not activated and performing the function of radiological assessment.

5.2 Interim Site Emergency Coordinator (ISEC) has determined, based on plant accident conditions or symptoms of an accidental radiological release, that an initial assessment of projected off-site doses has priority over other actions being performed by the EEC.

The following listed symptoms indicate that an airborne release may be occurring from within the RCA as guidance to the ISEC:

  • There is actual or suspected leakage of water, steam, or noncondensible gases from any vessel or piping system containing primary coolant, liquid radwaste, or gaseous radwaste.
  • Damage occurs to a submerged, irradiated fuel assembly with the resultant release of significant quantities of noncondensible gases.
  • Alarms occur on CAMs.
  • A fire occurs involving radioactive materials.

(Refer to EP M-6)

  • Verified alarm on radiation monitors RE-14/14R, RE-28/28R, RE-29, RE-15/15R, or RE-24/24R.
  • A major radioactive material spill occurs.

6. PRECAUTIONS 6.1 Do not use SPDS to obtain RMS readings. Radiological Monitor readings off SPDS may be based on different units of measurement than required as input to the calculations.

6.2 If the Main Condenser is available during a SGTR event with a stuck open Safety Relief or 10% Steam Dump to atmosphere, there are two release pathways.

6.3 Obtain an independent verification of your calculation whenever time permits to confirm no errors or incorrect assumptions about plant conditions.

6.4 Default release rates are extremely conservative and may result in higher classifications or PARs than would be warranted if actual release indications were available.

6.5 N-16 will be detected on the MSL Radiation Monitors while at power and may cause a false high off-site dose calculation.

6.6 This procedure shall not be used to evaluate compliance to Technical Specifications during planned effluent releases. Such evaluations shall be performed by the Chemistry Department.

6.7 Fuel Handling Accident (FHA) in Containment with Equipment Hatch open is a special case. Use the analyzed default dose rates and doses listed in Attachment 10.1 and go directly to EP G-I for comparison to the Emergency Action Levels (EALs).

7. INSTRUCTIONS NOTE: This calculation can be performed on the PPC using the turn-on code "EPR2."

7.1 RELEASE RATE CALCULATIONS 7.1.1 Obtain a working copy of Attachment 10.1.

7.1.2 Determine release source location as Plant Vent, Atmospheric Steam Release, or Unmonitored.

CAUTION: Do NOT use SPDS to obtain radiation monitor readings.

7.1.3 Gather and record the required information in accordance with the appropriate section of the form.

NOTE: Plant Vent Extended Range Rad Monitor RE-87 will automatically activate if the Normal Range Gas Monitors RE-14/14R approach their maximum reading.

7.1.4 Perform the required calculation to determine the release rate of Total Effluent and record the results in both this Attachment and Attachment 10.2.

7.1.5 If it is not possible to calculate a release rate, refer to the DEFAULT RELEASE RATES on Page 3 of Attachment 10.1 and choose the most appropriate value for input to Attachment 10.2. For an FHA in containment with equipment hatch open, use default dose rates and doses from Attachment 10.1 and go directly to EP G-l for comparison to the EALs.

7.2.4 Perform the required calculations to determine the TEDE and THYROID CDE RATES.

7.2.5 Project the RELEASE DURATION in hours as input to determining projected doses.

7.2.6 If a duration cannot be projected, use the DEFAULT DURATION of 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />.

7.2.7 Perform the required calculations to determine the TEDE and THYROID CDE at the Site Boundary (800 meters).

7.3 REPORTING THE RESULTS 7.3.1 Refer to EP G-1 and compare the results of the above calculations with the Emergency Action Levels.

7.3.2 Refer to EP RB-10 and compare the results of the dose calculations with the PAR determination criteria.

7.4 Advise the ISEC of any EAL thresholds that are exceeded based on site boundary dose rates and doses, or the need to revise PARs due to changing conditions.

7.5 CONTINUOUS ACTIONS 7.5.1 As directed by the ISEC, continue to perform assessment of airborne releases to support evaluation of EAL status and PARs by repeating the above instructions.

7.5.2 Contact Chemistry to request:

3. DEFINITIONS1 TC "DEFINITIONS" \F C \L "I'"

3.1 Habitability - a facility is deemed habitable when its occupants may perform their intended functions within (including, as applicable, access and exit) without undue risk from toxic, flammable, explosive, radiological or other hazards. Given the large potential variances in plant emergency risk and necessary facility occupancy times to respond appropriately, absolute numerical limits for these hazards are not pre-specified in this procedure. See RESPONSIBILITIES below for determination of habitability and relocation.

4. RESPONSIBILITIES[ TC "RESPONSIBILITIES" \F C \L " I 4.1 The Site Emergency Coordinator (SEC) shall, in general, determine relocation necessary for onsite ERFs. If time permits and the EOF is activated with the Recovery manager present, the SEC should obtain the RM's consent. However, in cases of rapidly escalating or highly dangerous or potentially dangerous conditions, the lead supervisor in each facility may order evacuation prior to receiving SEC/RM authorization.
