This exceeds the two day requirement date as required by BNP-QCP-10.27R4. Unit 1 valve Room 'A' was noted to be below housekeeping cleanliness requirement, however, this was immediately corrected, excepted as noted abov These housekeeping inspections were handled in accordance with Bellefonte's Quality Control Procedure BNP-QCP-10.27, Rev. No violations or deviations were identifie . Quality Audit Review the resident inspector reviewed the following Quality Assurance Audit for accuracy and completeness:

FBYT GT-11-0-1A GT-6-0-1-L 3/5/82 These welding performance qualification records were handled in accordance with Bellefonte's Quality Control Procedure, BNP-QCP-10.24, Rev. No violations or deviations were identifie . Storage of Rebar During the week of liarch 22, 1982, the resident inspector made a surveil-lance of the rebar yard to ensure that the rebar was being properly store Rebar storage is inspected per Bellefonte Quality Control Procedure BNP-QCP-10.27 Rev. 4. The inspector verified that the rebar was being properly stored. This closes Inspector Follow-up Item 438,439/81-29-08
" Storage of Rebar".
14. tiechanical Cleaning During the week of 11 arch 1,1982, the resident inspector noted that between construction flushes the site had mechanically cleaned an interior surface of the decay heat removal system without detailed controlled instructions and no quality control inspection. The area was mechanically cleaned to remove attached purge paper from the inside of the piping. The area cleaned was adjacent to temperature element IND-ITE-0DI!1-A adjacent to valve IND-VDBB-257- The section of piping was cleaned by mechanically grinding / polishing. General Construction Specification No. G-39, para-graph 5.1, states in part: "All cleaning process shall be controlled to ensure effective cleaning." Paragraph 5.2.1 states:
" Grinding and polishing shall be performed with a wheel or cloth that will ensure a cleanly cut surfac During grinding, the material or component part shall be oriented in a manner that particles will fall away from it. A vacuum hose may be employed near the work to remove fine airborne particles. Completed materials or components shall be cleaned, as required, to remove particles created by the grinding and polishing operation."
10 CFR 50 Appendix B, Criteria V states:
" Instructions, procedures, and drawings activities affecting quality shall be prescribed by documented instructions, procedures, or drawings of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Instruc-tions, procedures or drawings shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished."
The above mechanically cleaning operation is identified as Unresolved Item 438/82-09-09 " Mechanical Cleaning". Action is needed by the site to determine adequacy of procedures / inspections in similar condition _

1 Pipe Vibration During the week of flarch 22, 1982, the resident inspector identified sections of piping adjacent to the Unit 1 decay heat removal heat exchanger that was vibrating during a construction flus The piping in this area was vibrating with a displacement of 25 mills and a velocity of 1 inch per second. At present, the site (ie construction) has no criteria for acceptance of allowable piping vibration during the construction phas AflSI tt 45.2.B. Paragraph 4.6 states in part:
Temporary use of equipment or facilities to which this standard applies that are to become part of the completed project may be desira ble. Authorization for such usage shall be as provided for in the contract or by written approval from the responsible organizatio Such temporary use shall not subject the equipment or systems to conditions for which they were not designe The only acceptance criteria at Bellefonte for piping vibration is outlined in flechanical Design Standard DS-t12.16.1 Section 5.0 (Preoperational Test Program). Further investigation was performed by the resident inspector because of this condition. A telephone conversation was initiated between the llRC resident, D. Terrill (TVA), J. Kincaid (TVA) and R. ficColl (TVA)
concerning this conditio During the telephone conversation it was agreed that EfIDES would to be notified, by TVA construction, whenever piping was identified to be vibrating at a mode which could be visually note Further action is required by TVA to detennine if acceptable piping vibration limits need to be identified to construction during certain construction phases (ie flushing). This is identified as Unresolved Item 438/82-09-10
" Pipe Vibration".
1 Boric Acid Pump Room During the period between September 28 - October 2,1981, the resident inspector identified to the flechanical Unit Supervisor and the Assistant Construction Engineer of flechanical/ Welding, several questionable areas in Unit 1 Boric Acid Pump Room. There were indications that numerous welds had been re-melted to assist in alignment of pipe.
'
The site generated QCIR #13,352 on October 2,1981 to address this area and to cut out nine OflB welds and visually inspect these welds after they had been cut out. The results of welding engineering unit QC is as follows:

In addition, the welder infonned the resident inspector that the craft had used 2X4's to attempt to cold bend the pipe in the Boric Acid Pump Room to bring it within the specified alignment on the pipe drawings. Bellefonte's Quality Control Procedure BNP-QCP-10.13 Rev. 5 requires that all welding shall be perfonned using qualified detail weld procedures; however, this was not done in the above situatio This is identified as violation 438, 439/82-09-06 " Boric Acid Pump Room".
This action closes Unresolved Item 50-438/81-29-10 " Boric Acid Pump Room".
1 Receiving Inspection Checklist The resident inspector reviewed the contents of the receiving inspection checklist (Attachment A) of the following checklist:

- 82-383 (Task 41) 10/23/81 Component cooling pump shaft The receiving inspection checklist (RIC) denoted by (*) had CitTR's received marked (SAT); however, no C!!TR's were present. Also reviewed was TVA memo identifications #BLN 81082527 (dated August 24,1981) and BLN 811016008 l (dated October 6,1981) which state: "all expansion anchor shells and i wedge bolts are exempt from requirements of Certificates of Compliance (C0C)
i and Certified ltaterial Test Reports (CitTR) required by General Construction l Specification G-53". The RIC denoted by (*) did not have either C0C's or CllTR attached. The receiving inspection checklist denoted by (**) had j manufacturer's documentation marked (UNSAT) and no Certification of i

This is identified as unresolved . item 438, 439/82-09-07 " Receiving Inspection Checklist". Action is needed by the site to determine the location of the replacement shaft C0C's, i
18. Welding Inspector Training Program The resident inspector attended a session, conducted by Bellefonte's Welding-Engineering Unit, of welding inspector training on March 26, 1982. The j training consisted of three problems dealing with the following: '
' " Fit-up Code Butt Welds j Fit-up 2" Socket Weld
' Weld defects / wide weaves
- This session was conducted in accordance with Bellefonte's Standard Opera-
! ting Procedure WEU-SOP-715 R2 in an outstanding manner.
