3.0 DEFINITIONS

3.1 Chatter - abnormal rapid reciprocating motion of the movable parts of apressure relief valve in which the disk contacts the seat.

3.2 Opening Pressure - the value of increasing inlet static pressure of apressure relief valve at which the discharge become continuous asdetermined by seeing, feeling, or hearing.

3.3 Popping pressure - the value of increasing inlet static pressure at which thedisk moves in the opening direction at a faster rate as compared withcorresponding movement at higher or lower pressures. Popping pressureonly applies to safety or safety relief valves on compressible fluid service(e.g., air, nitrogen).

3.4 Ramp Rate - the rate of change at which the test pressure is increased.

3.5 Simmer - the audible or visible escape of fluid between the seat and disk atan inlet static pressure below the popping pressure and at no measurablecapacity. Simmer only applies to safety or safety relief valves oncompressible fluid service (e.g., air, nitrogen).

3.6 Thermal Relief Valve A relief valve whose only overpressure protectionfunction is to protect isolated components, system, or portions of systemsfrom fluid expansion caused by changes in fluid temperature.

REVISION SUMMARY

Revision 27: Incorporates reference to administrative procedure for the NC StateCoded Vessels program, 0ENP-62, responsibilities of Material and Contract Servicesgroup in section 4 and additional guidance on management of repairs of VR stampedrelief valves in Section 6 and 9. This is corrective action per NCR 324862-17.

Revision 26: Changes the seat leakage pressure for the 2-DSA-RV12, 2-DSA-RV14, 2-DSA-RV17, and 2-DSA-RV19 from 320 psig to 349 psig following replacement with newvalves per Master EC 62588 (Child ECs 67131 and 67132).

Revision 25: Changes the seat leakage pressure for the 2-DSA-RV2, 2-DSA-RV4, 2-DSA-RV7, and 2-DSA-RV9 from 320 psig to 349 psig following replacement with newvalves per Master EC 62588 (Child ECs 67129 and 67130). Also, changed Unit 1 toUnit 0 on cover page of this procedure.

Revision 24 incorporates IST Program update to the 2001 Edition of the ASME OMCode through OMb 2003 addenda by updating Section 2.0 and adding definition 3.6.

Revision 23: Deletes reviews by the ANII based on a relief request granted on 2/23/06.Adds steps for performing a bellows integrity test. Provides clarification on seatleakage calculation. Changes time between lifts to 5 minutes from 10 minutes for liquidmedia testing based on new code allowance. Adds steps to record ambienttemperature to the body of the procedure. Provides clarification to acceptance criteriain step 8.2. Added 2001 Edition with 2003 Addenda of the OM Code to the references.

Revision 22: Adds discussion in acceptance criteria to allow for Engineering evaluationof leakage. Adds the recording of pressure to the reseat check in the acceptancecriteria and body of the procedure. Corrects a deficiency in the leakrate calculations.

Adds guidance to procedure to contact Engineering for guidance prior to testing a valveat >110% of setpoint. Adds recording of the valve serial number to the data sheet in

Attachment 4.

Revision 21: Changes the setpoints for the 1-C41-F029A/B following replacement withnew valves per EC 51017 and 51020. Deletes step 6.15 which directed heating the1-C41-F029A/B since the SLC system on Unit 1 is no longer heat traced.
