PASS STATUS. REPORT- "?? 10/26/87

SUMMARY

gg7 7p '8 G h.30 The' PASS is designed-to. sample'the'following three itemet ci) Reactor Building Atmosphere CMFqypc

^

f L

.2) Decay! Heat System- 'l 1

3) Reactor Coolant System The Reactor Building Atmosphere sampling capability was tested by

.STP (Special1 Test-Procedure) 432 and; verified the system functioned properly.- The procedurevis undergoing results review / approval.

The Decay Heat. System sampling capability was tested by"STP.430.

Two-Non Conformance-Reports were written.on the sample 1 dilution l L acceptance criteria. The NCRs, which have been dispositioned and

t. approved, accepted the sample dilution results. The test has'been l

placed in the results review cycle. The-test demonstrated.the l ability;to-draw a Decay Heat System. sample, analyze.the sample for l boron and chloride, dilute the sample.and transfer the sample to- l a grab sample' flask and the; Intrinsic. Germanium Element-(IGE). ,l  !

The inline conductivity and pH instrumentation will be. tested with-  ! )

STP.1131 (Liquid Sample Depressurization and Total Gas. Test). .

l _j The Reactor Coolant System sampling capability will be. tested by STP.

433 which is:en hold.pending incorporation of initial Test 1 Working Group (TWG). comments. The procedure will be rewritten based the- lL l resultsJof STP.430 but it will.not be performed luntil'the reactor is l

at:15% power so that the' liquid' sample will'be at~its maxiumum l  :

temperature.. The ability of the system to depressurize and degas l a liquid sample will be' tested by STP.ll31.in mid November and STP.

433 will be used to verify the ability.to cool the sample. -l SYSTEM-MODIFICATIONS There:are a total of seven open Engineering Change Notices (ECNs) of which four are work complete and three are in progress. The status of each is as follows:

1) Work Complete i A-4711I ADD BACKUP SOURCE OF FLUSH AND COOLING WATER l Release of this ECN is pending performance of STP.433.

R-0381 ADD DHS SAMPLE CHECK VALVES

' Release of this ECH is pending valve in-service leak checks with the RCS at normal temperature / pressure.

,. R-0488 HYDROGEN MONITOR / PASS SAMPLE LINE HEAT TRACING Release of this ECN is pending approval of STP.793 (Heat Tracing Functional Test) test results.

R-0559 SAMPLE COLLECTION.'AND. ANALYSIS. SKID'(SCAS) CHANGES:

The only work pending is the installation.of lighting' in the vicinity'of the SCAS. However additional changes to the SCAS are. anticipated as a result of! .;

system testing. Final release of the ECN11s pending performance of STP.433. .

Two additional minor.ECNs are to be. created. One will relocate the nitrogen bottles used for system flushing.and dilution-to the same;

^ room containing the PASS control panel. .The second will' replace 1the.

backup flush / dilution water' conductivity' indicator and domineralizer,.

presently being leased,: with permanent' equipment.

TESTING y In' addition to the three primary Special' Test Procedures deNeribedi 1 1

in the

SUMMARY

there'are four' additional-tests. One was performed' 'l.

and three'are being' developed. .The status of each is as follows:

l

< STP.426 . SAMPLING TIMES USING THE PASS .

j The~ procedure has been written and will enter the review / l <l' approval cycle upon approval of P4SS Operating Procedures l' CHM-6001 (liquid sampling) and CHM-6005 (containment atmosphere sampling). CHM-6001 and CHM-6005 replace the-old procedure AP.313-1. STP.426 will measure the times required to perform these two procedures ~.

STP.428 MEASURMENT OF (SCAS) VOLUMES A AND B Development of Revision 3 to this procedure is in progress. l The procedure is in word processing and is expected to l enter the review / approval cycle by 10/28/87. l STP.793 HYDROGEN MONITOR / PASS HEAT TRACING FUNCTIONAL TEST This proce+:re was. performed but there was some difficulty in meeting the acceptance criteria. The test is on hold pending the results of a Non Conformance Report written l l on the test acceptance criteria.

functional testiof the system. Procedure' development is~pending manpower' availability.

CHEMISTRY PROCEDURES There.are five. Chemistry procedures associated with the PASS. :Two= '

have.been approved and three are in the review / approval cycle. . <

The two which have'been approved will be reformatted and resubmitted 1 for approval. . .l ~  ;

. TRAINING

P All Chemistry' Technicians have received.four hours of formal class-

. room training. .When procedures CHM-8001 (PASS liquid sampling) and

' . CHM-6005 (PASS;containanent atmosphere sampling) are-approved, six. ,

Chemistry Technicians will initially be given hands-on training.  !

The two procedures ~have'been-reviewed and are in the final approval'. .;- i phase'. '! :

PREVENTATIVE MAINTENANCE 3

- The FM program has.been reviewed by the PM Supervisor. A list of instruments not currently'in the program was developed and will'be used to'complie the necessary information to complete the PM 7 requirements. -Program development is.in progress. l I4 SPARE-PARTS Nuclear l Engineering' developed a list of spare parts and submitted it

-to the Procurement Group. The majority of those parts are on order.  !

The orderLfor a portion of the parts is on hold pending' additional j ordering information. l n

NRC INSPECTION NO. 87-26 Action has been taken on two items of concern expressed at this and previous inspections. The first item, NUPAC Shipping Cask labeling, I has:been closed, and the second item concerns lead blanket shielding.

PASS LEAD BLANKET SHIELDING

.The lead blankets have been labeled as-permanent shielding. .i Small cable will be used to tie the blankets together and when that is done this item will be complete.
