Subject Category:
Materials Control (40000)
Subcategory:
Material Identification (40000)
Element:
Requisitions (40510)
Concern:
WI-85-036-002 The basis for Element Seport MC-40510-SQN, Rev. 2, dated October 21, 1986 is Watts Bar Employee Concern WI-85-036-002 which states:
"Material requisitions are not being prepared, as per procedure; the requisitions are being changed or altered later (CI will not civulge additional information."
This concern was evaluated by TVA as potentially nuclear safety-related and potentially applicable to Sequoyah (generic).
II.
Su-mary of Issue The issue defined by TVA is that if purchase rec isitions are being changed or altered later (presumably subsegrent to review and approval),
it is possible that the changes or alterations were not properly reviewed In this case, inadequate material could and approved (concurred with).
be procured, accepted and installed.

III. Evaluati0n TVA personnel determined that Sequoyah Administrative Instruction AI-11 sets the recuirements for changing or altering quality-related procure-Pent documents.
A review by TVA of a random sample of site-initiated purchase recuisitions did not identify any discrepancies.
Interviews performed by TVA during the course of the investigation identified one change to a purcnase requisition without proper review and acproval; the discrepancy was identified during the site receipt inspection and documented on a Nonconforming Item report.
The TVA evaluation concluded that AI-11 is adequate in respect to controi-ling improper changes or altera' ions to quality-related purchasing docu-ments.
The one discrepancy identified appears to have been a singular occurrence, and was not indicative of any systematic problem.
No corrective action is required.
IV.
Conclusions The NRC staff believes that the TVA investigation of the concern was adequate, and their resolution of the concern as described in Element Report MC-40510-SQN, Rev. 2, is acceptable.
An NRC procurement inspection at Sequoyah during the periods September 15-19, 1986 and September 29 -
October 3, 1986 did not identify any examples of improperly changed or altered procurement requisitions.

TABLE 1 EMPLOYEE CONCERNS FUNCTIONAL CATEGORIES Construction - Concerns about the adequacy of construction 1.
practices, the quality of as-constructed facilities (excludinn welding and as-designed features), in-storage and installed maintenance prior to turnover to operations, rneasuring and test equipment and handling of ecuipment used during construction, and construction testing activities.
2.
Engireering - Concerns about the adequacy of the design process and the as-designed plant featurer. The design process consists of the technical and manecement processet that commerce with the identification of design inputs and lead to and include the issuance of design output documents.
3.
Operations - Concerns about operational activities, includino operator qualifications, maintenance or equipment needs, security, health physics, and ALARA (as low as reasonably achievable) implementation, and concerns about preoperational and surveillance testing.
4 Material Control - Concerns about the adequacy of material, including its procurement, receipt, handling, storage, and installation, and the adequacy of procedures governing material control.
5.
Velding - Crncerns about any aspect of welding, including welder or weld procedure cud ification, weld inspection / nondestructive examination, heat treatment, weld quality, filler material quality, and weld documentation.
6.
Intimidation, Harassment, Wrongdoing, or Misconduct - concerns about personnel conduct that interferes with the ability of employees to fulfill their assigned responsibilities, unauthorized actions taken against employees for fulfilling their assigned responsibilities, and illegal activit4s or violations of TVA policies and regulations.
