Page 4 of 25 3.0 DEFItiITIO?S A'ID ABBREVIATI0tS NOTE PWGS chemis try limits are categorized into three (3) distinct groups:

(1) Specifications (2) Operating Ranges (3) Typical Values Al th ou gh th e an al ys es/ limi ts ar e ca te gor iz ed into three (3) distinct gr ou ps, all are tr ea te d with equal importance in the laboratory.

3.1 De finitions 3.1.1 Specifications are those operating limits to which PWGS is p;

legally committed by regulatory requirements.

Opera tion Q~

outside specifications requires notifications and/ or actions as dic ta te d by th e a ppro pria t e re gula tions.

Because prolonged operation outside specification limits can have severe safe ty and/ or operational consequences, specifications have to p pr iority.

3.1.2 Proper sys tem chemis try control is rightly the dorain of PWGS l

mana gement. Therefore, PWGS defines the term operating ranges to designate those limits mandated and enforced by PWGS mana gement. The operating ranges include all limits nec.essary to adeq ua tely con tr ol th e ch emis tr y o f plan t s ys te ms.

ihile these operating ranges may not specifically be governed by the technical specifications, these are s trictly follwed as plant mana gem ent dic ta tes.

3.1.3 There are many o ther parace ters which the chemistry s ection desires to monitor in order to determine long term trends and s ub tl e ch anges in plan t ch emis tr y.

Analys es in this ca te gory are defined as being those typical values possessing significance, generally, only to the chemis try section.

Operation outside the range of typical values does not require immedia te action if the values are within operating ranges and s pe cifi ca tions, flowever, typical yalues may indicate possible adverse conditions which the chemis try s ection should further i

fw evalua te for the purposes of developing a total unders tanding l

(

of the significance of the conditions.

l Jy l

3.1.4 There are five (5) action levels which are used by the ch emis try s ection for ch emis tr y con tr ol o f the plan t s ys tems:

Page 5 of 25 3.1.4.1 Action level Ib. l's objective is to promptly identify the cause of a value to be out-of-range or out-o f-specifica tion without causing a need for power re duction. The action is to re turn the parace ter to within the normal value range or specification within one (1) week following the confirmed excursion. Parame ters not within the normal range or specification within one (1) week require progression to Action Level No. 2 (for those parameters having an Action Level No. 2 value).

3.1. 4. 2 The objective of Action Level No. 2 is to minimize system degradation by operation at reduced power while corrective actions are taken.

Action Level No. 2 requires a power reduction (typically 30% or less) within 4.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> of initiation and a change to Action Level No.

3 for parameters not within the operating range or specification within 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br />.

A 3.1.4. 3 The intent of Action Level No. 3 is to correct conditions I

)

whi ch ma y r es ul t in ra pi d s ys tem de grada tion. The action required is shutdown within four (4.0) hours and clean up by feed and bleed or drain and refill, as appropriate, until the operating range or specification is obtained.

3.1. 4. 4 Action Level No. 4 requires, or may require, tha t the source, s ys tem, tank, e tc., b e is olated and action s commenced to bring the specification within the appropriate limit prior to continued use. The a ction ma y require feed and bleed, blowdown, drain and fill, chemical additioas, r egeneratior., e tc.

3.1.4.5 Action Level No. 5 requires immediate verbal notification of the Shift Su;ervie or and th e tb.it Supervising Chemia t for parace ters s us pe c ted to b e ou tside o f the te chni cal s pe cifica tion limits. An immediate fo11ow-up sampie is required for verification as per Procedure 74AC-9ZZ02.

I n addi tien, i t is als o r eq uir ed th a t v er bal an d wri t ten communication of the follow-up analysis be immediately given to the Shift Su per vis or.

Exceeding Action Level No.5 may require the issuance of a chemistry Control Instruction (CCI) which will delincate the remedial actions rcquired to bring the 00S condition to within the Technical Specification, and which will describe the

/m applicable LCO.
