BACKGROUND j
A Nuclear. Safety Review Staff (NSRS) investigation was conducted to determine the validity of an expressed employee concern as received by the Quality Technology Company (QTC)/ Employee Response Team (ERT).
The concern of record as summarized on Employee Concern Assignment Request form from QTC and identified as XX-85-062-001 stated:
4 Browns Ferry, Bellefonte, Sequoyah - CI has been unoffi-cially informed that the latest drawings on all TVA l
nuclear power plant sites are not, in the majority of instances, the latest drawings at offsite TVA administra-tive offices / departments, including a computer printout that does not reflect the current drawing revision.
This can, and does, cause design, modification, and/or repair problems, i
II.
SCOPE i
A.
The scope of this investigation is defined by the concern of record which entails determining the validity of this concern, management recognition of the problem, and corrective actions being evaluated.
B.
The NSRS reviewed documents and interviewed cognizant personnel to
]
determine if offsite locations did have the current drawing revision and if the Drawing Management System (DMS) reflected the current information.
III.

Findings 1.
There have been frequent cases over the years of offsite g
document control centers not having the latest drawings ~and the drawing information system in place at the time not reflecting' the latest revision at the site..This has been true both for l
"as-constructed". and "as-designed" drawings and for both TVA and vendors. The DNS was implemented in December 1983 to provide online access for drawing information and is now the sole drawing information system used by P&E (Nuclear). However, i
documentation (Ref. 9) was reviewed _ stating that all the.
drawings used in design, operation, and maintenance are not in-the DNS.
The DNS data base is being expanded throughout P&E to l
enhance data integrity, i
l 2.
Review of DCC logs, workplan generated changes to drawings, and the DMS show that several months are often required for a j
typical drawing change to be processed.
{
3.
Significant Condition Report (SCR) SCR GENINS8501 was initiated on August 20, 1985, concerning data entry into the DNS not j
taking place in a timely manner. This SCR documents a large scale, corporate-wide problem that has been addressed with resources, goals, and reporting.
4.
TVA has recognized this problem and has taken action as evidenced by the following:
i A configuration management program was established June 13, a.
~
i 1985, by J. A. Coffey, Site Director, Browns Ferry Nuclear Plant (BFN), as part of the P&E Configuration Control Task j
Force (CCTF).

"DMS Overview II" memorandum dated July 15, 1985, from Michael L. Scalf, Chairman, DNS Subtask Group to R. D.
Guthrey, Chairman, P&E Configuration Control Task Force, i
summarizes current activities and reflects that each nuclear plant has at least one representative on the group.
J Communication between the CCTF and the DCC in Chattanooga c.
i has taken place to determine possible improvements, i
1 d.
Quality Notice NQAM Part V Section 2.4, entitled " Design Change Control System Using Design Change _ Supplements," was issued on September 9, 1985, to implement a pilot-design change control system at BFN.

l 5.
After reviewing several workplan drawing changes and interview-ing responsible employees, it was evident that there is not a
~
universal understanding of how TVA is maintaining configuration control via the DMS.
Many employees do not recognize the need for a DMS (and timely update to it) or the need to maintain current drawings at offsite locations.
6.
Management appears to be unaware of general configuration management systems, such as described in reference 15.
1 l
IV.
CONCLUSIONS AND RECOMMENDATIONS A.
Conclusions The employee concern is substantiated for the following reasons:
1.
The DMS has been less effective than it should be because:
a.
The DMS base has never been fully defined and loaded.
b.
Neither management nor employees have a universal understanding of what configuration control means and how it is to be implemented via the DMS.
c.
Management failed to put in place audit and feedback mechanisms on the sites to evaluate the DMS.
d.
A large time cycle in the drawing update process at the sites has resulted in out-of-configuration drawings in offsite document control centers.
2.
TVA has recognized that the existing DMS is in need of improvement. A task force has been established to address and resolve these problems, and significant progress has been documented (Refs. 9 and 13),
B.
Recommendations 1.
I-85-460-NPS-01, Prevent Recurrence Implement the corrective action and the actions required to prevent recurrence of significant condition report SCR GENIMS8501 as outlined below:
a.
Establish appropriate instructions within OE to:
(1) Define specifically which documents are to be entered into DMS.
3
e (2)
Establish all mandatory data elements to be entored.
(3) Standardize exact procedure of data entry.
(4) Provide schedule guidelines, b.
Classify all drawings in DNS into three categories, each with the following percent initial allowable date entry error rate:
(1) critical 0%
(2) primary 1%
(3) other 5%
c.
Nuclear projects ensure that appropriate management emphasis, procedures, resources, and training are in place to maintain the data performance identified above.
[P2]
2.
I-85-460-NPS-02, SON. BFN. WBN. and BLN Site Manatement Action i
.i Establish an expedited process and distribution system to handle drawing changes and updating of the DMS.
Delegate to the site QA unit the responsibility of auditing DNS site changes, tracking results, trending performance, and reporting on these i
parameters.
