ConatspoNetwer DSP-84-067 CC This is to respond to those items identified on CIO Tracked Action Item No.

085, which may apply to Module 120D. Those items which do not apply to Module .

120D are scheduled to be responded to by May 25, 1984.

PQCI NO. REV. ITEM RESPONSE C-1.40 12 a. Section 18 4 of Spec C-231 does not indicate that non-shrink placements shall be free of shrinkage cracks. FCR C-7660 further supports this state-ment. Per conversation with Project Engineering on May 21, 1984, Section 17.1 of Spec C-231 will be revised to delete the requirement that fill material be free from shrinkage cracks. Based on the above, this item does not impact Module 120D.

E-1.0 17 b. Field Change Request E-3550 was written to super-cede E-423, Sheet 301 requirements. PQCI Change Notice CN-E-1.0-17-3 was written and approved to comply with this requirement. Based on the above, this item does not impact Module /120D.

E-1.60 8 a. The reason for no cable radius or the word later was because Project Engineering had not received the information from the vendor. In those cases, if the cable was pulled a C R would be generated due to the lack of inspection criteria. ' Based on l the above, this item does not impact Module 120D.

P-2.30 5 r 6 s. PQCI P-2.30 is used in the Hanger Reinspection Pro-gram only and does not apply to Module 120D for Phase I/ Phase II release. These items are scheduled for response by May 25, 1984. Based on the above, l this item does not impact Module 120D.*

l l P-2.11 1 a. PQCI P-2.11 is used in the Diesel Generator Build-ing only and does not apply to Module 120 D for Phase I/ Phase.II release. This item is scheduled for response by May 25, 1984. Based on the above, this item does not impact Module 120D.

TAI NO. 085 Pogs 2 E-2.1 11 b, c, PQCI E-2.1 is not required for Module 120D. These d, g items are scheduled for response by May 25, 1984.

Based on the above, this item does not impact Module 120D. O MP-1.00 4 a. Activity 2.5 requires the QCE to verify that bolting material is properly tightened (torqued) to the re- l quirements of the applicable vendor procedures. In I the event no torque value is provided by the vendor, it is considered to be non-critical, and QCE involve-ment is not required.

The measurements addressed as a part of activity 2.4.3 shall be verified by the QCE in accordance with Project Engineering approved documents such as vendor proced-ures, applicable design change documents, drawings, etc... If limits for measurements, or tolerances, are provided on the aforementioned documents relative to measurement, QCE will inspect to those tolerances. -

Activity 2.4.2 will be clarified per Change Notice No. CN-MP-1.00-4-3 as follows:

2.4.2 Verify that materials are free of damage prior to reassembly. When evaluating an item for damage, the vendor procedure will be consulted first. In the event the vendor procedure does not provide damage criteria for the subject

. item, the QCE will evaluate the item based on approved Project Engineering criteria.

All damage shall be evaluated based on the aforementioned with the exceptions of the following approved Project Engineering criteria for valves and flanges:

1. Surface defects on nonmachined surfaces of valves shall not exceed 1/16 inch in depth.

2. Defects on surfaces other than the flange mating face shall not exceed 1/16 inch in depth. Defects such as scratches, gouges, and pits on the flange mating surfaces is unacceptable.

In addition, the reference criteria will delete paragraph 6.1.lb and include paragraphs 5.2.3 and 5.2.4 of Spec M-204 for valves and flanges respectively.

This clarification to Activity 2.4.2 will rein-force that for machined surfaces (with the excep-tion of flange mating surfaces) the vendor proced-ure will be consulted first, and subsequently, approved Project Engineering criteria if the vendoe '.'oes 0 7t provide criteria.

b. ~Any disassembly (including cutting) of an item will be performed in accordance with project approved procedures and vendor instructions as stated in Activity 2.1 of the subject PQCI. Any special clean-liness precautions relative to cutting, if necessary, will be addressed either in the vendor instructions or project approved procedures. The QCE is required to verify that disassembly is accomplished in accord-ance with those vendor instructions or project approved procedures as applicable. .

)

c. We comply with N45.2.3 by means of FPG-7.000 and its '

implementation. The overall acceptability of Bechtels method of compliance is being investigated by MPQAD.

Based on the above, this item does not impact Module 120D.

General 5 All PQCIs which require a fit-up inspection for welding have been reviewed. Only two PQCIs identified fit-up as generically in acc-essible. They are PI-1.90 and PI-2.90.

PI-1.90 covers welding of piping related instrumentation items.

The fit-up of these items is inaccessible upon completion of the welding activity.

PI-2.90 covers welding on non-ASME. supports and racks.

Change Notice No. CN-PI-2.90-01-1 has been written and approved deleting the statement'that fit-up is an inaccessible and requires an inspection generically to determine inaccessiblity.

General 7 If special instructions or. constraints are contained in Vendor documents and are determined by the PQCI preparer to require inspections, they will be referenced ,in the applicable PQCI. ,

General-8' It is not practical or appropriate to reference every possible vendor document which may apply for all commodities. The QCE is instructed per the PQCI that the vendor. documents apply and instructed in OJT on how to locate these documents.
