FINAL REPORT - DER 82-46 DEFICIENCY EVALUATION 50.55(e)

ARIZONA PUBLIC SERVICE COMPANY (APS)

PVNGS UNITS 1, 2, 3 1.

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 of 0-2485 psig. The transmitters are installed on the pressurizer as restricted range transmitters and are identified by the following tag numbers:

Tag No.

Model Range (PSIG)

Overpressure Range (PSIC)

IJRCA-PT-103 763 0-760

  • Should be 0-2485 psig ITT Barton Model 763 pressure transmitters tag numbers 1JRCA-PT-103 and 1JRCB-PT-104 were returned to ITT Barton for overpressure range

~

modifications from 0-1000 psig to.0-2485 psig. During this modification program, the thermal non-repeatability engineering changes were also implemented. During factory testing'it was determined the mandatory thermal non-repeatability modifications reduced the percentago-accuracy required for the restrictive 0-760 psig range.

ITI Barton concluded that the modified transmitters cannot meet the original 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 the Model 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 'Ec19054. The problem is defined in two parts as follows:

'1.

An equipment ' defect The equipment defect has been identified as a leakage current path between the zero and span adjustment potentiometers-end the case ground of the ir.strument. This current leakage becomes significant at higher temperatures (above 280*F).

ITT Barton has attributed this' condition'to

' existing metallic ' washers which are providing the leakage -

path.

t Mr. T. W. Bishop ANPP-29072 Page Two 2.

A, methodology error during factory transmitter calibration The methodology problem occurred during the tempe'rature compensation portion of the transmitter calibration. This methodology error resulted in an additional 0.25 to 0.5%

zero shift 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 temperatt:re compensation.

The ITT Barton Model 763 and 764 t-ansmitters pertinent to the above conditions are identified by the following unit tag numbers:

1,2,3JRCE-PT-100X 1,2,3JRCE-PT-100Y 1,2,3JRCA,B,C D-PT-101 1,2,3J RCA, B,C, D-PT-10 2

  • 1,2,3J RCA-PT-103

1,2,3J SG A,B,C, D-PT-102 3 1,2,3J RC A-I-T-11X 1,2,3JRCB-LT-110Y 1,2,3JCHN-LT-268 1,2,3JSIB-LT-311 1,2,3JSIB-LT-321 1,2,3JSIA-LT-331 E

  • Io be replaced b'y Rosemount Model 1153 Series D pressure transmitters, or other suitable 1 replacement (see 111.1).

Wr. T. W. Bishop ANPP-29072 Page Three II.

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 safetv-related devices. Based on the above, the conditions are evaluated by the P"NCS 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 has previously filed a 10CFR Part 21 report on the thermal non-repeatability problem.

III. Cor rective Ac tion 1.

C-E letter V-CE-18781 addresses the corrective action tbst the ITT Barten 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 transnitters, 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 I will require relaxation of the requirement for diversity of pressure sensing interlocks on redundant shutdown cooling system isolation valves identified in CESSAR-F Section 7.6.1.2.1.g.

C-E has further stated that their intent is to replace PT-103 and PT-104 with Rosemount Model 1153 Series D transmitters for Units 2 and 3 prior to fuel load for the respective units until such time that another qualified vendor is available.

2.

Bechtel will implement replacement of ITT Barton Model 763 transmitters with Rosemount Model 1153 Series D via DCP ISM-RC-105 for Unit 1 prior to fuel load.

DCPs 2SM-RC-105 and 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 1.

4.

C-E vill revise drawings and documentation applicable to the replan: met of ITT Barton Model 763 transmitters with Rosemount Model 1153 Series D for PT-103 and PT-104.

C-E will also submit revised Barton ducumentation identifying the thermal non-repeatability modifications.

2 Mr. T. W. Bishop ANPP-29072 Page Four 5.

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

Metallic washers will be replaced by non-metallic washare a.

as a field modification, in accordance with ITT Barton Field Change Proedure 0764-1240B Log No. N001-1.01-4?S-1.

This field modification will be implemented on all pressure transsitters as identified in Section IB, with the er.c(ption of PT-103 and PT-104 which have been replaced as identified in Paragraph 111.1.

b.

C-E will return the following ITT Barton transmitters for the Balco resistors and metallic washer modifications:

1JRCE-PT-100X IJSIA-PT-343 1JSGB-PT-1023B IJSGC-LT-1123C via NCR SJ-3230 IJRCB-LT-110Y

& CE letter V-CE-20416 IJSIB-LT-311 IJSIB-LT-321 IJ SIA-LT-331 IJSIA-LT-341 2JSIA-PT-333 via DCP 2SM-RC-118 2JSGA-LT-lll3 c.

All Unit 3 transmitters modifications will be implemented via DCP 3CM-RC-ll8, as follows:

Transi,itter to be modified on site.

32SGB,D-LT-lll3 3JSGB,C-LT-1123 3JSGE-PT-1013 The t.bove transmitters do not require Balco reisitor modifications and will have metallic washers changed only.

All NCRs which have been initiated as a result of these -

conditions will be dispositioned as " repair" in accordance with the applicable DCPs.
