Audits The resident inspector reviewed the following Quality Assurance audits for
.
accuracy and completeness:
f AUDIT No.
TITLE No. OF DEFICIENCIES i
BN-G-81-01 Preparation, Review, and Control of
QC Procedures
BN-G-81-02 Drawing Control
Paragraph 9.c of the Quality Assurance Staff Procedure (QASP) 7.1, Rev. 6
" Auditing Construction Activities" states:
"The lead auditor immediately i
brings a deficiency to the attention of management having responsibility in the area audited to permit maximum time for the comprehension of the deficiency., determination and prompt implementation of corrective action.'
It has not been determined by the resident. inspector how this immediate notification to management has been implemented by the QA organization.
This item is identified as unresolved item 50-438/81-07-01 and 50-439/81-
-07-02 "Immediate notification of management to QA audit deficiencies". The
,
resident inspector has requested the QA organization to notify him how this immediate notification of management to the above audits was performed.
,
9.
Radiation Survey
'
!
The resident inspector performed a radiation survey of the Welding
.
Engineering Unit Non-destructive Examination Building on site and obtained I
readings around a gang box of 1 mR/hr in several areas adjacent to and on top of this box. The gang box contained Radium 192 pills used in gamma radiography. The NRC RII office was immediately notified of this condition.
,
,
i The appropriate State of Alabama health physics personnel were also notified. TVA site personnel immediately moved the contents of the gang. box to Radiography Building (TVA Dwg #40lN127-1 Rev 1) for storage.
No violations or deviations were identified.

10. Minimum Design Wall Thickness
-
The resident inspector reviewed the recommended disposition of NCR's 1131 and 1285. TVA En-Des approved the minimum design calculated wall thickness for an 8" - sch 120 feedwater spoolpiece to be.585" and for 2" - sch 40 reactor building spray piping to be.0248".
Section 3641.1 of ASME 1974 i
Code gives the minimum thickness of pipe wall calculation formulas.
l However, this formula incorporates a coefficient for corrosion and erosion.
l This corrosion and erosion would be introduced to the piping section over
[
the life of the plant. The resident inspector questioned En-Des approval
'
'
for using this minimum design ca.lculated wall thickness for new piping sections which have not been introduced to corrosion and erosion on a plant l
under construction. The resident inspector requested TVA En-Des to explain j
the use of the minimum design calculated wall thickness on new piping

sections under construction activities. This is identified as unresolved item 50-438/81-07-03 " Design minimum wall thickness for pipe section".
11.
Surveillance of Pipe Runs During the surveillance of the common zone elevation 629 Auxiliary Building, the resident inspector identified a section of chemical addition and baron recovery piping supported by hanger 0NB-0017 which appears to be cold sprung. TVA's General Construction Specification G-43 paragraph 2.6, states in part that cold springing is not permitted unless specified on design drawings. The resident inspector requested TVA to evaluate the above noted condition to determine if the chemical addition and boron recovery piping is cold sprung in this area.
This is identified as unresolved item 50-438/81-07-02, " Cold Springing of Pipe Runs".
12.
Installation of Mechanical Heating and Ventilation System Between February 20-27, 1981, the resident inspector observed work being performed on the structural installation of the mechanical heating and ventilation system to Unit 2.
During this inspection, it was determined that several areas were being erected contrary to TVA approved procedures.
These areas consisted of the following:
a.
Faur welds were made on February 18, 1981, at elevation 686'6" (Detail J55-J55 of TVA 3AWO910-00-55 Rev 11) without any welds specified on the above drawing.
^
'
b.
Several welds were made on the mechanical heating and ventilation structure which did not coincide with the weld symbols identified on TVA drawing 3AWO910-00-55 Rev. 11.
'
c.
The welder was performing the welds without weld cards in the immediate
.
work area and four weld cards did not exist.
Conversation between the welder, foreman and resident inspector confirmed that the foreman had not given the missing four weld cards to the welder when the weld was being accomplished.
This is identified as violation 50-439/81-07-01 " Failure to follow procedures when installing the mechanical heating and ventilation structures".
