PURPOSE To provide a procedure for the analysis to.be performed on the primary coolant during post-accident condition.
(Fuel cladding failure.)
B.
SAFETY Observe Radiation' Protection Procedures.
C.
PRECAUTIONS 1
E 1.
Due to the high dose rates and contamination levels which l
5 are to be expected with this kind of a sample, extreme :are I
41 and good sampling technique must be adhered to and followed.
.I 8!
2.
Laboratory Supervision shall be consulted on all activities l
p associated with analysis and counting any material obtained I
i for post-accident analysis-
{
3.
All attempts to analyze samples will be followed with the I
f most restrictive Health Physics practices.
Constant H.P.
monitoring will be provided and adhered to.
A minimum of l
t two persons will be required to analyze the sample.
i
. t i
f
.4.
Samples greater than 100 R/hr will be shipped to an outside vendor for analysis.
See HNP-8016 for Radioactive Shipment j ;
procedure.
(100 R/hr/ liter = approximately 10 mci /cc).
l NOTE h
~At no time during analysis will personnel be allowed to receive more than 1.25 R unless a Lab Supervisor j
1 or his designee signs FORM 2 of HNP-8002 Authorization f
to $xceed Administrative Exposure Guides.

NOTE l
All equipment must be placed behind lead shielding when performing the analysis.
At no time kill the liquid waste be allowed to enter the radwaste system.
l WE
{
Steps E.2, E.3, E.4, E.5, and E.6 all need to be performed in the sample hood whenever possible.
E.l The following analyses are to be performed on the primary coolant sample:
E i
(1)
D.O.
HNP-7225 l
9 (2) pH HNP-7202 or 7203 o!
(3)
Conductivity HNP-7204 or 7205 l
U!
(4)
Chlorides HNP-7004 E
(5)
Iodine Separation HNP-7110
{
(6)
Borons HNP-7003 m
(7)
Gross Alpha p
(8)
Isotopic The analysis will be performed while the technicians are fully dressed out.
Working time will limited to dose received.
High range (LOR or 20R) dosimeter and finger rings will be worn in addition to normal dosimeters.
Prior to analysis, be sure to sign in on a blanket R.W.P.
l 1.
D.O.
I e lh
(
The D.O. probe will nave to be placed in line after the 75 l }F mi sample bomb has been taken or prior to taking the sample.
!I a.
. Place D.O.
probe into sample line using quick
{
disconnects and follow procedure HNP-4825 for valve e
manipulation.
,l li NOTE
);-
l' The center connection of the D.O. probe is the inlet and the farsided connection is the outlet.
Read D.O.
directly on meterE*
face.
The D.O. meter will be used with.,a.',
50 foot remote cable.

COUNTINO ~ ~ NOTE The counting room must be habitable f.or counting samples. If it is not, refer to HNP-7251 for pro-I cedure for mobilizing the counting room. i' 1. Open Ge(Li) shield and place sample on the first shelf af the sample holder and close Ge(Li) shield door. T-2. Press the collect button on the MCA and observe the % dead E! time (%DT) meter. If % DT is greater than 20%, stop i collecting spectra by pressing the collect button again and redilute sample until it reads less than 1 mr/hr. If %DT is i less than 20% acquire spectra for 1000 seconds or as directed by the Counting Room Foreman. p) 3. When 1000 seconds or count time is finished, the light behind the collect button will go out. Check calibratidn to i see if it has drifted. E 4. Remove sample from Ge(Li) shield and retain for other t! analysis as may be required later. 5 G. ANALYZING SPECTRA p NOTE 'a I Refer to FEP-7215 Ge(Li) systems for additional iniormation g on counter system. n] 1. Transfer spectra from MCA to 9845 computer using computer program "CI-8100" or "OR7010." m Y i g 2. After spectra has been transferred completely, run computer program "RWICNE" and answer question as required by computer display. Submit printout to Counting Room Foreman for [ approval and review.
