EXECUTIVE SUMMARY
Point Beach Nuclear Plant
NRC Inspection Report 50-266/98010; 50-301/98010
The inspection included a review of measuring and test equipment (M&TE) procedures. In
addition, the ir,t,pector reviewed the calibration of M&TE; condition reports associated with
M&TE; and disposition of out-of-tolerance, lost or damaged M&TE.
'
Maintenance
The overall control of M&TE was acceptable. The licensee had made several changes
.
to improve the control of M&TE by storing them in a locked room and requiring full-time
attendants to dispense the instruments (Section M3.2).
The M&TE procedures were weak. Three M&TE procedures contained conflicting
.
information and did not contain adequate guidance for proper M&TE control. For
example, the licensee 'was in the process of developing one procedure to control M&TE
for operations, engineering, electrical / mechanical maintenance, and instrumentation and
controls (l&C) (Section M3.1).
Evaluations of some lost, damaged, or out-of-tolerance M&TE were not performed or
.
inadequately performed (Section M3.2). One violation of NRC requirements was
identified.

ERRort Details
This inspection included a review of measuring and test equipment (M&TE) procedures. In
addition, the inspector reviewed the calibration of M&TE; condition reports (CRs) associated
with M&TE; and disposition of out-of-tolerance, lost or damaged M&TE.

Maintenance Procedures and Documentation -
M3.1 M&TE Procedures
a.
Insoection Scoce (62702)
The inspector reviewed the following M&TE procedures:
MWP 112,"MOV Load Sensing Equirment Calibration," Revision 1, June 1,
.
1994
NP 8.7.1, " Maintenance - Control of Measuring and Test Equipment," Revision 2,
.
August 29,1997
NP 8.7.2," Calibration and Control of Measuring and Test Equipment
.-
(Instrumentation and Control)," Revision 1, June 27,1997
OM 5.4.9," Control of Operations Department Measuring and Test Equipment,"
.
Revision 0, June 14,1995
b.
Observations and Findinas
The present M&TE procedures provided guidance for the control of M&TE in the areas
of electrical / mechanical, instrumentation and controls and operations. The engineering
staff used electrical / mechanical maintenance procedure NP 8.7.1, although the
procedure did not state whether its use included the engineering department.
The licensee recognized that the three M&TE procedures were not providing adequate
guidance and included conflicting requirements. As a consequence, the procedures
were being revised to improve the control of M&TE and to develop one procedure that
would be used by maintenance, engineering, and operations. In addition, the inspector
noted that current procedures contained conflicting information. For example,
operations procedure OM 5.4.9 stated that M&TE that cannot be located shall be treated
and evaluated as cut-of-tolerance, while the electrical / mechanical procedure NP 8.7.1,
stated that lost equipment will be treated as out-of-tolerance only when the equipment
exceeded its recalibration frequency by 25 percent, and the instrument and control (l&C)
procedure NP 8.7.2 did not include guidance or requirements for lost M&TE. In addition,
none of the procedures required that the M&TE be signed out. Although all the
3

.
,
procedures required that evaluations for out-of-tolerance M&TE be performed, none
included guidance when as-found data could not be determined. Finally, none of the
present procedures provided guidance for the control of M&TE that was checked out for
extended periods of time.
c.
Conclusion
The licensee's M&TE control procedures were weak. The procedures contained
conflicting information and did not contain adequate guidance for proper M&TE control.
For example, the licensee was in the process of developing one M&TE procedure that
should improve the control of M&TE.
M3.2 M&TE Program
a.
Insoection Scoce (62700)
The inspector reviewed M&TE calibration records and CRs.
b.
Observations and findinas
In early 1997, the licensee determined that the M&TE area was poorly controlled.
Maintenance personnel would not sign out M&TE and would keep the equipment for
extended periods of time without locking up the equipment. As a result, the licensee
implemented a number of corrective actions and controis that included storing M&TE in
a locked room and requiring full-time attendants to dispense and log out M&TE. In
addition, a number of CRs were written that identified problems in this area. The
corrective actions were effective and the control of M&TE improved.
The inspector noted, through a review of log records, that most of the M&TE was
returned at the end of the day and that the control of M&TE was acceptable.
The inspector reviewed calibration records and noted that in all cases M&TE was
calibrated within its calibration frequency. However, in some cases, the evaluations
were not performed for lost or damaged M&TE and for M&TE found out-of-tolerance, or
the evaluation was inadequate. In an audit report issued in January 1998, the licensee
identified that the fo!!owing operations M&TE were lost: OPSDH-002, OPSDP-001,
OPSSW-009, and OPSTW-002. Procedure OM 5.4.9, Section 3.4, stated in part,
"M&TE which cannot be located for recalibration when scheduled shall be treated as
out-of-tolerance and evaluated as such." As of March 13,1998, the licensee had not
evaluated these instruments as being out-of-tolerance. Additionally, the inspector noted
that electrical / mechanical maintenance load cell MCLC-001, calibrated on October 17,
1996, had an as-found slope of 1.441. Procedure MWP 112 stated that if the as-found
slope was not within 1.348-1.244, then the load cell was out-of-tolerance. The licensee
did not evaluate this instrument as being out-of-tolerance, as required by procedure
NP 8.7.1, Moreover, M&TE MCCP-007 was damaged and sent out for repairs on
January 28,1998, but the CR that would initiate the evaluation was not issued until
- March 13,1998. For another instrument, MCMA-003, the licensee issued CR 98-0654
4
,
.
I
on February 13,1998, because the DC current and voltage circuits were not functional.
~
In the evaluation and operability determination, the licensee concluded that MCMA-003
was functional when it was used during post maintenance testing and that damage to
the M&TE occurred during shipment to a commerciallaboratory. Consequently, the
licensee did not consider the instrument to be out-of-tolerance and no further action was
taken. However, the inspector noted that as-found data could not be obtained due to
the damage to the DC circuit. Therefore, the licensee could not determine how much
the instrument was actually within or outside of the required tolerance. Although
required by procedure NP 8.7.1, the inspector noted that the CR did not include an
evaluation or require a retest of plant equipment that was tested with instrument
MCMA-003. For the seven M&TE mentioned above, the licensee did not evaluate the
use of these instruments and, as a consequence, failed to take proper corrective
actions.
Title 10 of Code of Federal Regulations, Part 50, Appendix B, Criterion XVI, Corrective
Action," requires, in part, that measures be established to assure that conditions
adverse to quality, such as deficiencies and deviations are promptly identified and
corrected in the case of significant conditions adverse to quality, the measures shall
assure that the cause of the conditions is determined and corrective action taken to
preclude repetition. The failure to evaluate lost, damaged, or out-of-tolerance M&TE is
a violation of 10 CFR Part 50, Appendix B, Criterion XVI (VIO 50-266 /98010-01(DRS);
50-301/98010-01(DRS)).
c.
Conclusions
The calibration of M&TE was acceptable and corrective actions were, in general, good.
,
The licensee improved control of M&TE by storing the M&TE in a locked room and
requiring full time attendants to dispense and log out M&TE. However, evaluations for
out-of-tolerance M&TE were not performed or were inadequate. One violation of NRC
requirements was identified.
V. Management Meetings
X1
Exit Meeting Summary
The inspectors presented the inspection results to members of licensee management at the
conclusion of the inspection on March 18,1998. The licensee acknowledged the findings
presented.
The inspectors asked the licensee whether any materials examined during the inspection
should be considered proprietary. No proprietary information was identified.
