- 1. Purpose NOTE:
- 1. NSD 228 Applicability Determination and a 50.59 screening is required to make major changes to this section. Minor changes per NSD 703 can be made without a Applicability Determination.
- 2. Seven Control copies and one Information Only copy of this CSM shall be routed to the Emergency Preparedness Team within three (3) working days following any approved changes/modifications.
This section provides guidelines on the administration and use of chemistry post accident procedures and the precautions that should be observed during the use of these procedures.
Special attention is given to limits and precautions associated with the execution of a procedure during a projected accident. Personnel requirements and procedure work locations will be given for personnel exposure consideration. Also, a listing of RIAs of interest to Chemistry for planning and assessment activities is included in Enclosures 6.1 and 6.2. This information is intended only as guidelines with the knowledge that an actual accident situation may deviate greatly from a projected scenario.
- 2. Guidelines 2.1 Limits and Precautions NOTE:
These Limits and Precautions do not apply to the task for Addition of Caustic to the LP1 (RCS) System. This task is a "time critical task" and therefore is not subject to the below L.
Limits and Precautions.
2.1.1 Valve alignments should NOT be made and samples should NOT be taken without prior authorization from the TSC/OSC.
2.1.2 Do NOT attempt any phase of sampling or analysis without Radiation Protection coverage.
2.1.3 ALL personnel will need prior authorization from the OSC to exceed any exposure limit.
2.1.4 Radiation levels of the sampling and analysis area should be measured continuously during all phases of sampling, sample preparation, and analysis.
2.1.4.1 Air activity should be determined by use of installed air monitors or through the use of portable air sampling equipment.
Chemistry Manual 5.2 Page 3 of 13 2.1.4.2 Area dose rates should be established by the use of installed radiation monitors or by portable radiation survey instruments.
2.1.4.3 Portable shielding, remote handling equipment, video equipment, etc., should be used where practical during sample preparation and sample analysis.
2.1.4.4 All personnel working in the lab area and transporting samples shall monitor their personal dosimetry frequently to avoid exceeding maximum dose limits.
2.1.5 The post accident analysis should be done in a fume hood and/or other precautions should be taken to avoid the release of gaseous activity.
2.1.6 Radiation exposure to an individual during all phases of sampling should be limited so as not to exceed an annual accumulative exposure of 2 rem whole body; 50 rem skin of whole body; 50 rem extremities; or 15 rem eye respectively. All personnel will need prior authorization from the TSC/OSC to knowingly exceed any exposure limit. The exposure received may require an occupational exposure penalty and/or a medical decision as to whether an individual can continue in radiation work.
2.2 Waste Disposal 2.2.1 Determine by detailed planning meeting, the exact course of action to be taken. Under no condition should liquid or solid wastes be disposed of without prior specific RP directions.
..2.2 Designate a sealable carboy as the "Post Accident Lab Waste" container. This container should be shielded and used as an interim liquid waste disposal container for all liquid analytical waste.
2.2.3 Request RP to designate an area where the "RCS Flush" bottle(s), "RCS Sample" bottle(s) and "Post Accident Lab Waste" container may be stored until final disposal.
2.2.4 In the event an area is grossly contaminated and cannot be decontaminated, evaluate the need for shielding or protective covering to prevent the spread of airborne activity.

- 4. Suggested Actions 4.I Normal Operating Conditions:
Observation:
Loose part or mechanical failure has caused suspected loss of some fuel integrity.
Actions:
0 Do not over react, close coordination with OPS and RP will be necessary to understand where and how to sample coolant.
- First find out exact status of unit (subcritical, pressure, temperature, # of RCP on, letdown flow rate, area monitor readings?)
- If the unit is shutdown, then remember that samples will show normal coolant fission product spiking - must compare to earlier unit trip results.
- Have RP survey letdown piping (if in service) and compare to normal values before deciding which method to use in sampling.
Chemistry Manual 5.2 Page 12 of 13
"* For truly mechanical damage, gap activity isotope should increase (Xenons, Kryptons, iodines) with much smaller increases in (Strontium, Barium, Cesium, less mobile isotopes).
With gap activity release, degassing of coolant fission gases will be much more pronounced. Appropriate respiratory protection should be considered while sampling.
4.2 Overheat Condition Without Fuel Melt Observation:
RB pressure and temperature increase. Suspect loss of coolant to Reactor Building.
Actions:
- If ES actuation occurs, then letdown will be automatically secured thus rendering normal sample point useless (Ops may manually override) o Make immediate plans to move necessary equipment to RW facility or Environmental lab for chemical analysis of boron and pH. Dose rates may render Primary lab useless.
Before deciding which sample location to use, a careful evaluation of all data should be performed.
- 1. Boron concentration can be calculated based on injection volumes and known concentrations.
- 2. RIA readings from RIA 57, 58 can closely estimate failed fuel percentage without need for sampling.
- 3. If recirculation of water through vessel is not available, the PALS J-leg sample will not be representative.
- 4. Core exit thermocouple readings and mapping can aid in estimating area and extent of core damage.
- If electrical system load shed has occurred, then many of the normal power supplies to the Chemistry group may be unavailable without Operations assistance.
Chemistry Manual 5.2 Page 13 of 13 4.3 Fuel Melt Actions:
"* All of Section 4.2 action items are applicable.
"* Expect higher levels of Barium, Strontium and Praesyodimium from fuel matrix loss.
"* Expect high suspended solids in any sampling attempted.
"* Both hydrogen percentage and RIA 57, 58 readings can and should be used in lieu of sampling, at least until dose levels have significantly dropped.
Boron as a criticality concern should be minimal - weighing the small benefit of a sample versus the extreme risk to an individual(s) should be considered.

.5 Chemistry Manual 5.2 Technical Basis for Page 1 of 3 Caustic Addition Calculations Initial Addition Based on Pounds of Boric Acid:
The initial addition is based on the ability of one pound of caustic to neutralize 17 pounds of boric acid. This value was calculated using the methodology described in the Babcock & Wilcox Water Chemistry Manual (BAW-1385), Section 8 (1990 revision) and was confirmed by benchtop titration studies. Please reference Memo to File, dated 1-24-96, "Results of Caustic Titration Study", File
- OS-715.00 for further details.
Subsequent Additions Based on Measured pH:
The basic assumption is that boric acid (H3BO 3) behaves as a simple monoprotic acid versus the complex monoprotic acid that it is. Thus, it was assumed that when boric acid is placed in water only the H2BO 3 borate ion is produced. Typically, boric acid in water will produce 3 to 4 different borate ions (Ref.: B&W or Westinghouse literature on boric acid). The equation will therefore read as foliows:
H 3BO 3 <--> H+ +
H 2BO3 where the acid dis;sociation constant (Ka) equation would be K, = {H-BO3-1 {H+}

pH-= -Jog{(14 }

For calculation simplification purposes, it is assumed that the only species contributing to the neutralization equation listed below are NaOH, H 3BO 3, and H1O:
{Na+}
+ {H+}
{OH-}
{H.B0 3} -=

By substitubrng Equations 1, 2, and 3 above into equation 4 and soiving for the sodium ion concentration, the amount of caustic added to the reactor coolant water can be determined giveri the system pH. The equation would be:
-Na+}
= K3{H3BO 3}/(0-pti)
+
1 014-pH (Eqn. 5)
.5 Chemistry Manual 5.2 Technical Basis for Page 2 of 3 Caustic Addition Calculations Since it is desired to adjust the system pH to a point between 7.0 and 8.0, then the desired amount of sodium necessary to achieve a system pH of 7.5 can be determined by solving equation 5 above for a pH equal to 7.5. Therefore, subtracting the sodium concentration calculated at the actual system pH from the sodium concentration at the desired pH of 7.5 yields the amount of sodium necessary for pH adjustment.
At a pH of 7.0, the terms 10-PH and 1 0 14-pH cancel each other. This leaves the following equation:
{Na+}
= (Ka'{H 3B0 3 }I( 10 -PH)) - (Ka{I-13 B0 3 }/(10-pH)

.5 Chemistry Manual 5.2 Technical Basis for Page 3 of 3 Caustic Addition Calculations The initial guesses for the A and B coefficients were calculated from apparent monoprotic dissociation constants using a pH - specific conductivity computer program. The initial coefficients were A = 9 x 10-6 and B = 3.09 x 10-13. Laboratory data was then utilized to fine tune the coefficients. Titrations of various boron concentrations resulted in coefficients A = 4.7 x 10-6 and B
= 1.6 x 10-13. Thus, the formula for calculating the quantity of caustic to add based on pH as shown in Enc. 6.3 is:
