I will provide initiating cues and reports on other actions when directed by you. Ensure you indicate to me when you understand your assigned task. To indicate that you have completed your assigned task return the handout sheet I provided you.
INITIAL CONDITIONS:
- 1. Unit 1 is currently performing a liquid waste release from the Monitor Tank Building.
- 2. Low Pressure Service Water (RL) Flow transmitter 0RLP5080 (RL Disch Flow) and OAC points C1P0903 and C2P0903 (RL Line A Disch Flow-Hourly Average) are INOPERABLE and have been removed from service.
- 3. The RN system is aligned to the RL discharge header.
- 4. Units 1 and 2 are both at 100% power.
INITIATING CUES:
You are directed to calculate the total RL discharge flow using Enclosure 13.2 (Total Discharge Flow Calculation Sheet) of PT/0/A/4250/011 and determine if adequate flow exists to continue the release per the LWR currently in progress. Record your answer in the spaces below.

Applicant calculates RL Discharge pressure as 164.3 ft. (Acceptable range: 163 - 165 ft. based on accounting for rounding and truncation.)
This step is critical because improper entry affects the calculation for Total RL Discharge Flow.

___ UNSAT STANDARD:
Applicant calculates Total RL discharge flow to be 27,854 gpm.

Applicant calculates Total RL Discharge flow to be 18,105 GPM.

UNSAT STEP 11 Determination of adequate RL flow. CRITICAL STEP STANDARD:
___ SAT Applicant determines that Total RL Discharge Flow is LESS than the "Minimum RL Flow interlock setpoint for radionuclides (gpm)" required ___ UNSAT by and listed on the Liquid Waste Release Permit Report, and that the release may NOT continue.
This step is critical for ensuring termination of a release with inadequate dilution flow.
EXAMINER NOTE:
The Liquid Waste release Permit Report requires at least 27,600 gpm RL flow in order for the release to continue. If the applicant does NOT apply the dilution safety factor (listed in STEP 10 of this JPM), it will appear that adequate RL flow DOES exist (27,854 gpm). But with the required dilution safety factor, RL flow can only be calculated as 18,105 gpm: inadequate for the release to continue.
