DEFICIENCY EVALUATION 50.55(e)
ARIZONA PUBLIC. SERVICE CONFANY (APS)
PVNGS UNITS 1, 2, 3 I.
Description of Deficiency A.
As documented by Combustion Engineering (C-E) letters V-CE-20050, V-CE-16845 and 18182, ITT Barton Model 763 pressure transmitters were provided and' installed in Unit I having a overpressure range of 0-1000 psig. The same model transmitters supplied for Units 2 and 3 have the. correct overpressure range 1
of 0-2485 psig.. The transmitters are installed on the
- pressurizer as restricted range transmitters and are identified by the following tag numbers:
Range (PSIG)
Overpressure Range (PSIG)
Tag No.

1JRCA-PT-103 763 0-760
- 0-1000 1JRCB-PT-104 763 0-760.

)
- Should be 0-2485 psig ITT Barton-Model 763 pressure transmitters tag numbers 1JRCA-PI-103 and 1JRCB-PT-104 were returned ;to ITT Barton for overpressure range.
- modifications from 0-1000 psig to 0-2485 psig. Duriug this modification program, the thermal non-repeatability engineering i
changes were also implemented. During factory uesting it was.
- determined the mandatory thermal;non-repeatioility modifications
~
reduced the percentage accuracy required for the restrictive 0-760
_ psig range. ITT Barton concluded that the modified-transmitters
~
cannot meet the originsi design criteria requirements for.PT-103 and PT-104-for Unit 1, 2 and.3.
B. _ITT Barton has. filed a 10CFR Part.21 report concerning the1Modell 763 and 764 electronic transmitters, based on thermal non-repeatability -at nominal in-containment ' ambient temperatures. This report is~ addressed in C-E letters V-CE-17362 and V-CE-19054.. The problem is defined in two parts
~
as follows:
1.
An equipment defect
.The equipment defect _has been identified as a :1eakage current' path between.the zero and span adjustment
. potentiometers.and the case ground of;the instrument. This-current leakage becomes significant at higher temperatures (above 280*F). ~ITT Barton has attributed this condition to existing metallic washers which are_provi' ding the leakage
-path.

Page.Two 2.
A methodology error during factory transmitter calibration The. methodology problem occurred during the temperature compensation portion of the transmitter calibration. This methodology error resulted _ in an additional 0.25 to 0.5%
zero shif tz error over a temperature range of 80*F to 130*F, with proportionately higher errors at higher temperatures.
ITT Barton has attributed this condition.to wrong value Balco resistors installed -for temperature compensation.

-the above conditions are_. identified.by the following unit tag numbersi 1,2,3JRCE-PT-100X

Analysis of Safety Implications The conditions of incorrect overpressure range on the pressurizer transmitters and the generic thermal non-repeatability of the Model 763 and 764 ITT Barton pressure transmitters could cause physical damage and unreliable setpoint calibration of safety-related devices. Based on the above, the conditions are evaluated by the.
PVNGS Project as reportable under. the requirements of 10CFR50.55(e),
since if these conditions were to remain uncorrected, it would constitute a significant safety condition. The supplier ITT Barton j
has previously filed a 10CFR Part 21' report on the thermal j
non-repeatability problem.
f III. Corrective Action I
1.
C-E letter V-CE-18781 addresses the corrective action that the i
ITT Barton Model 763 pressure transmitters for PT-103 and PT-104 on Unit I will be replaced with qualified Rosemount Model 1153 Series D pressure transmitters that meet the restricted range criteria. Replacement of PT-103 and 104 with qualified
~~
Rosemount Model 1153 Series D transmitters, will mean PT-103,
,104, 105 and 106 will all be Rosemount Model 1153 Series'D transmitters. C-E~also addresses.that-this replacement for the first. fuel cycle of PVNGS Unit l'will' require relaxation of the requirement for diversity of pressure sensing interlocks on i
redundant shutdown cooling system isolation valves identified-in CESSAR-F Section 7.6.1.2.1.g.
In addition, unti1~such time j
'another qualified-vendor is available,.PT-103 and PT-104 will be
~
replaced with Rosemount Model 1153. Series D transmitters in 4
Units 2 and.3 prior to fuel load for the respective units.
1 2.
Bechtel will, implement replacement of ITT Barton' Model 763 transmitters with Rosemount Model 1153 Series D via DCP ~
1SM-RC-105 for Unit 1 prior to fuel load. DCPs 2SM-RC-105.and i'
3CM-RC-105 will be issued for Units 2 and 3 prior to fuel' load for the. respective units.
3.
PVNGS.SAR_. Change Notice-No. 1137 will'be: issued' revising Section.
1.9.2.4 to identify a deviation'from the diversity; requirement; design basis: contained in CESSAR-F Section.7.6.1.2.1.g.
The SAR:
change will be' incorporated prior to fuel. load'for Unit 11 4.; C-E~will revise drawings;and documentation applicable to'the-replacemetfof'ITT Barton Model 763. transmitters with Rosemount.
Model'1153 Series Difor~PT-103 and PT-104.C-E will also submit arevised Barton' documentation' identifying'the thermal' non-re peatability. modi fications. _

C-E letter V-CE 19054 addresses the corrective action required for the thermal non-repeatability problem on all ITT Barton 4
l Model 763 and 764 transmitters. The corrective action will
. consist of two (2) engineering changes as follows:

a.
Metallic washers will be replaced by non-metallic washers as a field modification, in accordance 'with ITT Barton Field Change Proedure~0764-1240B Log No. N001-1.01-418-1.
This field modification will be implemented on all pressure l
transmitters as identified in Section IB,'with the j
