SSINS No.: 6835 IN 85-66 UNITED STATES NUCLEAR REGULATORY
COMMISSION
OFFICE OF INSPECTION
AND ENFORCEMENT
WASHINGTON, D.C. 20555 August 7, 1985 IE INFORMATION
NOTICE NO. 85-66: DISCREPANCIES
BETWEEN AS-BUILT CONSTRUCTION
DRAWINGS AND EQUIPMENT
INSTALLATIONS
Addressees
All nuclear power reactor facilities
holding an operating
license (OL) or a construction
permit (CP).
Purpose
- This information
notice is to alert recipients
of a potentially
significant
generic problem regarding
as-built construction
drawings not correctly
or completely
reflecting
equipment
installations.
Modifications
of existing installations
also may be susceptible
to the problems discussed
in this infor-mation notice. It is expected that recipients
will review the information
for applicability
to their facilities
and consider actions, if appropriate, to preclude a similar problem occurring
at their facilities.
However, suggestions
contained
in this information
notice do not constitute
NRC requirements;
therefore, no specific action or written response is required.Description
of Circumstances:
Fermi Unit 2 During routine NRC prelicensing
inspections
of as-built design and construction
drawings and specifications
at Fermi Nuclear Power Plant Unit 2, from April 1984 to October 1984 several discrepancies
in the electrical
and instrumenta- tion and control (I&C) installations
were discovered, which construction
and preoperational
testing had not identified.
In response to the NRC findings at Fermi, the licensee conducted
an approxi-mately 100 percent reinspection
of electrical
and I&C installations.
That inspection
effort resulted in the identification
of over 7300 discrepancies
and errors between as-built field configurations
and associated
design and con-struction
drawings and specifications.
There were 154 discrepancies
which, if left uncorrected, could result in the loss or incorrect
function of a safety-related
component
or system. Examples of these discrepancies
were wiring errors, unidentified
jumpers, wrong tubing connections, and wrong installed
components.
There were 300 discrepancies
that had correct design documents
but incorrect
installations
that could impair safe operations.
8508050449 IN 85-66 August 7, 1985 Examples of these discrepancies
were ungrounded
cable shields, missing hard-ware, and wrong nameplates.
There were 1900 discrepancies
which had correct as-built hardware but deficient
drawings.
Examples of these discrepancies
included wiring installed
that was not shown on the applicable
drawing, wiring details that differed from the installation
drawing, and incorrect
cable numbers on the drawings.
There were 5000 additional
minor discrepancies
which would not have impacted or impaired safe plant operations
directly such as incorrect
wire tags, equipment
layouts that did not match the drawings, and inconsistencies
in wire tagging methods. Extensive
actions by the applicant were necessary
to correct the most significant
discrepancies
before an operat-ing license was issued by the NRC.Rancho Seco A reactor coolant system high point vent line addition was made at Rancho Seco during the 1983 refueling
outage as part of the TMI required modifications.
Part of the modification
included adding cross bracing and revising supports for the adjacent nitrogen supply line. Although records indicate this work had been done and inspected
it had actually not been performed.
In addition, a removable
piping spool piece used to isolate the nitrogen supply was not replaced by a rigid piece as required.
The resulting
unsupported
4 foot length of 1 inch diameter pipe caused a fatigue failure at a high point vent weld resulting
in a-20-gallon
per minute non-isolatable
primary coolant leak. This event is similar to previous discrepancies
identified
between the as-built and as-designed
piping systems at a number of nuclear power plants that led to issuance of IE Bulletin 79-14, "Seismic Analyses for As-Built Safety-Related
Piping Systems." Resolution
of the actions requested
by that bulletin has resulted in extensive
reanalysis
and/or modifications
of piping systems in many nuclear power plants.Construction
Appraisal
Team Inspections
A number of problems with construction
activities
which may lead to discrepan- cies between equipment
installations
and as-built drawings were identified
by NRC Construction
Appraisal
Team (CAT) inspections
at 10 facilities
from Septem-ber 1982 to January 1985.Discussion:
To assure that an adequate level of safety exists or will exist at all nuclear power plants, it is required that all safety related as-built design and construction
drawings match the plant hardware.
Requirements
and measures to control documents
are identified
in 10 CFR 50, Appendix B; NUREG-0800, Standard Review Plan, Rev. 2 of Section 17.1; ANSI N45.2-1977, Section 7; and ANSI N.8.7-1976, Section 5.2.15, as applicable.
IN 85-66 August 7, 1985 No specific action or written response is required by this information
notice.If you have any questions
about this matter, please contact the Regional Administrator
of the appropriate

1 IN 85-66 August 7, 1985 Discrepancies
Identified
During Construction
Appraisal
Team Inspections
During the Braidwood
CAT inspection
the NRC team noted a failure to annotate unincorporated
design changes on controlled
design documents.
The most signif-icant finding in this area was design change documents
written against super-seded revisions
of the approved drawings;
this resulted in a pipe support being installed
and inspected
to other than the latest approved design.Programmatic
concerns were noted by the NRC team in two areas during the Shearon Harris CAT inspection:
(1) lack of verification
of piping and pipe support/restraint
location to original design requirements
and (2) lack of an ongoing program to effectively
identify and resolve hardware clearance
problems early in the construction
process. Both of these concerns involve practices that could result in extensive
inspection, analyses, and rework efforts very late in the construction
schedule.The River Bend CAT inspection
noted that numerous cable tray supports did not meet the drawing configurations
that were utilized for determining
support loading. The applicant
failed to consider the generic implications
of identi-fied deficiencies.
Improper or inadequate
fastener locking was identified, including
unbent or missing cotter pins, no staking of threads, loose or missing locknuts, and inadequate
lock wiring. These deficiencies
indicated both inadequate
field quality control (FQC) inspection
and alteration
of completed
and accepted work by construction
personnel.
The Nine Mile Point 2 CAT inspection
identified
problems in the document control program that indicated
the crafts and inspectors
may not have been using the latest design documents
in the performance
of their work. Inspection
reports often did not reflect the drawing revision to which the installation
was inspected.
Adding to the document control problem was the high rate of design change initiation
and the inability
to maintain and revise construction
drawings in a timely manner to reflect such changes. The NRC CAT inspectors
identified
that over 30 percent of all design change documents
resulted from errors or inadequate
information
provided on previously
issued changes.Furthermore, rather than taking measures to identify the reasons for the high change notice generation
rate, a procedural
requirement
for incorporation
of changes in drawings had simply been circumvented
by the licensee to allow construction
to continue without timely design change update.The results of the Comanche Peak CAT inspection
indicated
a breakdown
in fabrication, installation, and inspection
in the HVAC area. The licensee's
quality assurance
program had not ensured that certain hanger, support, elec-trical and mechanical
equipment
was installed
