<< RPV Level Caution >>
Caution 1 A RPV level instrument may be used to determine RPV level only when the conditions for use specified below are satisfied for that instrument.
NOTE
- Reference leg area drywell temperature is determined using Attachment 18, Level Instrument Reference Leg Area Drywell Temperature Calculations, ERFIS or Instructional Aid based on Attachment 18. ...............................
- If the temperature near any instrument run is in the UNSAFE region of the Attachment 19, RPV Saturation Limit, the instrument may be unreliable due to boiling in the run. ...........................................................................................................
- Immediate reference leg boiling is not expected to occur for short duration excursions into the unsafe region due to heating of the drywell. The thermal time constant associated with the mass of metal and water in the reference leg will prohibit immediate boiling of the reference leg. Reference leg boiling is an obvious phenomenon. Large scale oscillations of all water level instruments associated with the reference leg that is boiling will occur. This occurrence will be obvious and readily observable by the operator. Additionally, if the operator is not certain whether boiling has occurred, he can refer to plant history as provided on water level recorders or ERFIS. Reference leg boiling is indicated by level oscillations without corresponding pressure oscillations. .................................
Instrument Conditions for Use Narrow Range Level Instruments Unit 1 Only: The indicated level is in the C32-LI-R606A, B, C (N004A, B, C) SAFE region of Attachment 20.
C32-LPR-R608 (N004A, B) Unit 2 Only: The indicated level is in the Indicating Range 150-210 Inches SAFE region of Attachment 21.
Cold Reference Leg Shutdown Range Level Instruments The indicated level is in the SAFE region of B21-LI-R605A, B (N027A, B) Attachment 22.
Indicating Range 150-550 Inches Cold Reference Leg To determine RPV level at the Main Steam Line Flood Level (MSL), see Attachment 30.
Attachment 30 has two curves: The upper curve is for reference leg area drywell temperature equal to or greater than 200°F.
The lower curve is for reference leg area drywell temperature less than 200°F.
