2. Action on Previous Inspection Findings | |||
(Closed) Unresolved Item (155/84-15-01): Administrative procedures did | |||
not require a documenteo 10 CFR 50.59 review for temporary modifications | |||
(liftedleadsandjumpers). The inspector verified that the applicable | |||
administrative procedures had been revised to require this review for all | |||
temporary modifications not previously addressed. | |||
3. Program Areas Inspected | |||
a. Maintenance Program | |||
During the most recent SALP period (SALP 5), the licensee was rated | |||
as a Category 2 in the maintenance area. This represented a decline | |||
in performance from the SALP 4 period in which the licensee was rated | |||
a Category 1. In addition, SALP 5 noted that performance continued to | |||
decline during the rating period. The primary reason for the decline | |||
in the SALP rating was the increase in the number of problems requiring | |||
maintenance attention. A particular concern was expressed about those | |||
that could have been prevented by a mnre aggressive PM program (i.e., | |||
emergency diesel generator problems). Other concerns were the lack of | |||
- | |||
2 | |||
.. . | |||
increased management attention to reverse the trend toward more main- | |||
tenance problems and the occasional lack of aggressive action in solving. | |||
maintenance problems. This inspection was augmented to assess the | |||
reasons for the declining performance and any remedial actions being | |||
taken by the licensee to reverse it. | |||
(1) Inspection Results | |||
The inspector reviewed the procedures controlling maintenance | |||
activities, maintenance history files for selected pieces of | |||
equipment, completed maintenance order packages, recent licensee | |||
audits of the maintenance program, the SALP 5 Report, Licensee | |||
Event Reports for 1983-85, and Deviation Reports. The inspector | |||
also interviewed licensee personnel responsible for the mainten- | |||
ance program. Specific observations were as follows: | |||
a_ During the review of completed maintenance orders (M0's), | |||
the inspector noted that the equipment outage requests | |||
(EOR's) were not always completed. Further investigation | |||
indicated that this problem had been identified in the | |||
4 licensee's 1984 audit of maintenance activities and was | |||
incorporated in that report as an observation. During the | |||
licensee's 1985 audit of this area, the problem was found | |||
to be worse and the matter was upgraded to a finding. This | |||
is considered an unresolved item pending NRC review of the | |||
licensee's prompt corrective action (155/85010-01). | |||
b The inspector reviewed the licensee's program for independent | |||
verification of system alignment for removal from and return | |||
' | |||
to service. When protective tagging (for personnel protection) | |||
is required, independent verification of system alignment is | |||
. | |||
performed for removal from service; however, the tagging | |||
system does not provide for independent verification of | |||
l system alignment for return to service. In addition, instru- | |||
mentation and control procedures for calibrations do not | |||
require independent verification of system alignment during | |||
i either removal from or return to service. | |||
3 | |||
The inspector discussed this issue with licensee personnel, | |||
l | |||
and they stated that the E0R system does require action to | |||
i determine equipment operability prior to returning it to | |||
' | |||
service. In some cases, this would represent independent | |||
i | |||
verification of system alignment. In other cases, only the | |||
item worked on may be tested and overall system alignment | |||
may not be verified. The Nuclear Operations Department | |||
, | |||
; | |||
; Standard governing this area was revised during this | |||
inspection to reflect this fact permitting operability | |||
testing to be used for independent verification only when | |||
l | |||
personnel hazards precluded visual verification by a second | |||
; qualified individual. This is considered an unresolved | |||
! item pending NRC review of the revised operating procedures | |||
(155/85010-02). | |||
l | |||

_ | |||
. . | |||
c- The maintenance staff is experienced and well qualified. | |||
The licensee is generally able to replace experienced | |||
personnel that leave with personnel experienced in their | |||
particular craft. Systems training is provided to the new | |||
personnel. Some skill training is also provided. While no | |||
formal on-the-job training program is used, an apprentice | |||
type program is employed. This provides " hands-on" | |||
experience with plant equipment to new staff members under | |||
the supervision of experienced personnel. An INP0 accredited | |||
maintenance training program is being pursued. | |||
d_ Approximately 4000 maintenance orders (M0s) are processed | |||
each year. At the time of this inspection there were 2 | |||
M0s open from 1982 (under review for necessity), 8 from | |||
1983 and approximately 115 from 1984. The backlog appeared | |||
to be reasonable. Preventive maintenance (PM) tasks were | |||
being completed in reasonable agreement with the PM schedule. | |||
~ | |||
e To assess the reasons for the declining SALP performance, | |||
the inspector reviewed the examples listed in SALP 5. The | |||
inspector also reviewed LER's for 1983-1985 for other main- | |||
tenance problems which led to reportable conditions. | |||
Specific observations are as follows: | |||
. The problems with the emergency diesel generator | |||
involved a fuel pump shaft failure, loose and pitted | |||
contacts, and failure of a drive coupling to the | |||
engine cooling water pump due to long term wear. | |||
While the diesel engine had recently been overhauled, | |||
the remainder of the system had not been examined or | |||
refurbished. It does appear that a more complete PM | |||
program for this sytem would have prevented these | |||
problems. | |||
. An example of a corrective maintenance situation | |||
that might have been prevented by more aggressive | |||
corrective action involved the recirculating pump seal | |||
leakoff valves (IA60A and IA608). These valves are no | |||
longer used to control seal leakage but remain in a | |||
full open position. In February 1984, the packing in | |||
IA60A failed leading to a high containment radiation | |||
level and a forced outage to repack the valve. During | |||
April 1985, IA60B packing failed leading to another | |||
forced outage to repack that valve. The inspector | |||
reviewed the deviation report associated with IA60A to | |||
determine why IA60B was not repacked after IAG0A | |||
failed. The licensee evaluation of the IA60A failure " | |||
appeared to conclude that the reason for the failure | |||
was that the valve was not backseated. It also noted | |||
that there was some packing left and that the packing | |||
was still pliable. Corrective action included repacking | |||
IA60A, adjusting IA60B packing, and backseating the | |||
valve. A change was also initiated to an operations | |||
valve checklist to routinely ensure these valves were | |||
4 | |||
. . | |||
backseated. One item not addressed was anticipated | |||
packing life and establishing a repacking schedule for | |||
these valves. Considering the consequences of packing | |||
failure it would appear prudent to have repacked | |||
IA60B at the same time as IA60A or at least scheduled | |||
it for the next outage. The valves had not been | |||
repacked within the period covered by their machinery | |||
history records (1977 was earliest entry). | |||
(2) Conclusions and Recommendations | |||
There is evidence of weaknesses in the PM program and a lack of | |||
management aggressiveness in upgrading that program based on plant | |||
experience to prevent equipment failures. This is particularly | |||
important considering the age of the plant resulting in the | |||
increased potential for end-of-service-life failures. The | |||
licensee has taken some actions to reduce equipment failures and | |||
increase reliability. Among these are budgeting for replacement | |||
of recorders and transmitters, assessing the replacement of | |||
neutron instrumentation, and the establishment of a PM program | |||
for limitorque operators. However, the following additional | |||
actions should be-considered: | |||
~ | |||
a Treat corrective maintenance M0s more like corrective action | |||
documents. Specifically, a review should be performed to | |||
ensure the root cause has been properly identified and an | |||
assessment made to determine if better PM (or other action) | |||
could prevent recurrence. The assessment should include | |||
generic implications and be completed prior to closing the | |||
M0. | |||
- | |||
b A formal evaluation should be made for important plant | |||
equipment to assess the potential for end-of-service life | |||
failures and determine actions necessary to prevent these | |||
failures. | |||
~ | |||
c The infonnal assessments of equipment problems currently | |||
performed by the maintenance staff should be documented in | |||
the maintenance history files to ensure their availability | |||
for future assessments. | |||
I | |||
b. QA/QC Administration | |||
The licensee had recently reorganized resulting in the transfer of | |||
some functions previously performed at the General Offices (GO) to | |||
the Big Rock Point (BRP) site organization. The transfer of these | |||
, | |||
functions necessitated changes to the QA program implementing | |||
l procedures and increased the the BRP QA staff workload. Because of | |||
l NRC concerns relative to the safety impact, the inspector assessed | |||
' | |||
these changes to determine the adequacy of the procedure changes, if | |||
BRP QA personnel were qualified to perform their new responsibilities, | |||
and the impact of the added workload on the ability of the BRP QA | |||
staff to adequately perform their assigned tasks. | |||

L. | |||
, . | |||
(1) Procedure Changes | |||
The top tier implementing documents for the QA program are the | |||
Nuclear Operations Department Standards (N0DS). These standards | |||
specify the organizational responsibilities and requirements | |||
for various subject areas (such as fire protection and plant | |||
security. Due in part to the reorganization, 16 N0DS had been | |||
revised and 15 cancelled. Changes to Administrative Procedures | |||
(APs) (second tier implementing procedures) had not been | |||
completed at the time of this inspection. | |||
a_ Inspection Results | |||
The inspector reviewed the revised and cancelled N0DS and | |||
identified the following concerns: | |||
~ | |||
1 The inspector noted that in some cases a revised NODS | |||
referenced a cancelled NODS. In one case the reference | |||
was a "use" reference: N0DS-Q01, (" Corrective Action | |||
and Nonconforming Items") was revised to require QA | |||
Support to trend certain items in accordance with | |||
h0DS-M05 (" Supplier Evaluation and Selection") which | |||
had been cancelled. The inspector asked whether the | |||
requirements of the cancelled N0DS were included in | |||
either the remaining N0DS or the Administrative Proce- | |||
dures (APs). Licensee personnel stated that the | |||
situation had been reviewed and they were satisfied | |||
that all requirements of the cancelled N0DS were | |||
addressed; however, they recognized that cancelled N0DS | |||
were still referenced in both the APs and active N0DS | |||
and could not ensure that there were no other cases in | |||
which the reference was a "use" reference. The | |||
licensee's current plan was to delete references to | |||
the cancelled N0DS in the APs or N0DS when they were | |||
revised for other reasons or at the time of their | |||
biennial review. The inspector was concerned that in | |||
the case where the reference was a "use" reference, as | |||
in the case noted above, this schedule could lead to | |||
the use of uncontrolled documents (cancelled N0Ds) or | |||
the lack of specific direction for performing safety | |||
, | |||
related activities. This is considered an unresolved | |||
item pending further NRC review (155/85010-03). | |||
2_ The NODS provide a convenient reference to applicable | |||
requirements for a specific subject area and provide | |||
a vehicle for G0 level interpretation of these require- | |||
ments. The inspector was concerned that the APs | |||
become more vulnerable to missing requirements in | |||
those areas where a NODS had been cancelled since the | |||
gap between the baseline requirements (Facility | |||
License, NRC approved QA program, etc.) and the APs | |||
had been widened. The preparation of APs becomes more | |||
difficult since the baseline documents must be searched | |||
to identify applicable requirements. The workload | |||
! | |||
6 | |||
< | |||
, - | |||
and potential for error are thus increased. The | |||
licensee is planning to mitigate this problem to some | |||
extent b | |||
Matrix (yQARM). | |||
revising | |||
TheitsQARM | |||
Quality Assurance | |||
is currently a twoRequirements | |||
dimensional | |||
matrix relating requirements to implementing procedures. | |||
The revision will add a third dimension relating | |||
subject to requirements. This is considered an open | |||
item pending further NRC review of the adequacy of the | |||
revised QARM for identifying regulatory requirements | |||
relating to subject areas (155/85010-04). | |||
_3_ The N0DS also provide a vehicle for establishing | |||
corporate level policy related to regulatory | |||
requirements in a subject area. The inspector was | |||
concerned that for those subjects covered by the | |||
cancelled N005, this policy making authority had been | |||
effectively transferred to the plant and department | |||
level managers thereby reducing corporate level control. | |||
The licensee stated that this had been discussed | |||
extensively and that corporate level management felt | |||
they had adequate control through the performance | |||
appraisal (MB0) system. .The inspector had no further | |||
questions concerning this subject. | |||
4 Some changes in the revised N0DS, taken collectively, | |||
appeared indicative of weakened controls. Specifically: | |||
. The Corrective Action Review Board (CARB) will | |||
no longer review completed Event Reports (ERs) | |||
or Deviation Reports (DRs). They will review | |||
only the initial reports. | |||
. ERs and DRs will no longer be prioritized. | |||
. Applicability of many N0DS is for safety-related | |||
items only. The issues of "important to safety" | |||
and " reliability" are not addressed. | |||
. | |||
Overdue corrective actions will no longer be | |||
explicitly escalated to higher levels of | |||
management. | |||
. | |||
The Plant Review Committee (PRC) will no longer | |||
review Q-list changes. | |||
. The PRC will no longer review all violations of | |||
procedures required by the Technical | |||
Specifications, only those considered to have | |||
significant safety impact. | |||
Individually, these items may be justified on the basis | |||
of efficiency or line management responsibility or both. | |||
However, as noted above, they do appear indicative of | |||
weakened controls. | |||
7 | |||
. | |||
. | |||
b_ Conclusions and Recommendations | |||
Based on the observation noted above, the inspector | |||
concluded that the cancellation of some of the NODS | |||
was premature in that the licensee did not adequately | |||
ensure that they were no longer required as a "use" | |||
reference nor provide a fully operational alternative | |||
for efficient identification of requirements for | |||
specific subject areas (eg, QARM). Further, overall | |||
operational controls may have been weakened. Based | |||
on these conclusions, the following actions appear | |||
warranted: | |||
- | |||
1 The licensee should perform an immediate and in | |||
depth review to identify any case where a | |||
cancelled NODS is required as a "use" reference. | |||
In those cases, immediate corrective action | |||
should be taken. | |||
2 The revision to the QARM should be given a high | |||
priority. | |||
3_ The licensee's audit and trending programs | |||
should be augmented on a temporary basis to | |||
focus on these changes to determine if they have | |||
impacted the safety of facility operation. | |||
(2) Site QA Workload and Staff Qualifications | |||
The site QA staff had been assigned new functions previously | |||
performed by the GO QA staff. These functions were: | |||
. Fuel vendor inspections | |||
. Inservice inspection program | |||
. In-line QA reviews for the G0 projects | |||
organization (BRP projects) | |||
. Equipment environmental qualification (EEQ) | |||
program for BRP | |||
. Appendix R (safe shutdown) building for BRP | |||
. Core physics packages for BRP | |||
The lead responsibility for the fuel vendor inspections haa | |||
originally been reassigned to BRP. However, the lead was later | |||
transferred to the Palisades QA staff with BRP providing auditor | |||
support. The EEQ program and Appendix R building were primarily | |||
one time efforts. | |||
The inspector interviewed site QA personnel and reviewed formal | |||
workload projections to determine if the site QA organization | |||
was qualified and adequately staffed to perform these newly | |||
assigned tasks. | |||
8 | |||
.. o | |||
a Inspection Results | |||
The inspector made the following specific observations: | |||
1 The workload projection did not include all categories | |||
of work performed by the QA organization. Non-projected | |||
categories included surveillance (approximately 9% of | |||
1983 effort), training, corrective action closecut | |||
reviews, independent assessments, consulting, and | |||
other miscellaneous activities. For those categories | |||
that were projected, the projection for 1985 was based | |||
- on actual manpower expended during the first 6 months | |||
of the year. It included neither the additional effort | |||
required to support the refueling outage scheduled for | |||
late 1985 nor any increase in workload due to the | |||
reorganization which was not fully reflected in the | |||
effort expended during the first six months of 1985. | |||
Site QA personnel felt that the 1985 workload for the | |||
projected categories would be approximately 10% higher | |||
than projected. No projections were available beyond | |||
1985. | |||
The projected categories required an increase of 10% | |||
of the total QA manpower available over that expended | |||
in 1984 in the same categories (adjusted for the | |||
anticipated 10% increase in the 1985 projection for | |||
these categories). An increase in the manpower require- | |||
ments for the non-projected categories of training and | |||
consulting was also experienced during the first 6 | |||
months of 1985. The manpower to support the increase | |||
in the projected and non-projected categories was to | |||
' | |||
come from a decrease in the number of surveillances to | |||
' | |||
be performed during 1985. The site QA staff felt that | |||
' those surveillances performed would also contain less | |||
depth than those performed during 1984. Thus, it | |||
l | |||
appeared that an increase of 10% of available manpower | |||
j for projected categories plus an increase in non-pro- | |||
! jected categories plus added refueling outage effort | |||
I was to be recovered by reducing (not eliminating) | |||
' | |||
effort in a category utilizing only 9% of available | |||
manpcwer during 1984. This did not appear feasible | |||
to the inspector. | |||
- | |||
2 The inspector was satisfied that the QA staff was | |||
qualified to perform the newly assigned functions. | |||
However, extra time was required by the staff to | |||
l | |||
familiarize themselves with the specific requirements | |||
l | |||
i | |||
in certain areas such as inservice inspection and fuel | |||
! | |||
vendor audits. Also, one QA staff member (representing | |||
25% of available staff hours) was still in training and | |||
l- | |||
currently qualified to perform only certain categories | |||
of work. This impacted the flexibility in assigning | |||
staff work and increased staff training time. | |||
9 | |||
~ | |||
,. . | |||
b Conclusions and Recommendations | |||
Based on the observations noted above, the inspector con- | |||
cluded that workload projection for the site QA staff was | |||
inadequate in that historical data was used to project | |||
workloads in a changed situation and only a portion of the | |||
total workload was projected. Further, the uncertainties | |||
noted above not withstanding, the site QA organization did | |||
appear to be understaffed, at least for the short term. | |||
Based on these conclusions, the following recommendations | |||
are made: | |||
1 A more meaningful workload projection for the site QA | |||
staff should be made. The projection should include | |||
all categories of effort and reflect the full impact | |||
of newly assigned functions. The projection should | |||
also extend beyond 1985. | |||
2_ The site QA staff should be temporarily supplemented | |||
at least until all current staff members are fully | |||
qualified, the 1985 refueling outage is complete, and | |||
the above projection is completed. Any permanent | |||
change in staff level should be based on the | |||
completed projection. | |||
4. Unresolved Items | |||
Unresolved items are matters about which more infonnation is required in | |||
order to ascertain whether they are acceptable items, violations, or | |||
deviations. Unresolved items disclosed during this inspection are | |||
presented in Paragraphs 3.a.(1).a_, 3.a.(1).b_, and 3.b.(1).a.1. | |||
5. Open Items | |||
Open items are matters which have been discussed with the licensee, which | |||
will be reviewed further by the inspector, and which involve some action | |||
1 | |||
on the part of the NRC or licensee or both. An open item disclosed | |||
' | |||
during this inspection is presented in Paragraph 3.b.(1).a.2. | |||
6. Exit Interviews | |||
The inspector met with licensee representatives (denoted in Paragraph 1) | |||
on June 21, 1985 and July 12, 1985, and summarized the purpose, scope, and | |||
findings of the inspection. A final summary of the inspection findings was | |||
presented to the licensee via telecon on July 26, 1985. The licensee | |||
indicated that the inspector had no access to proprietary information | |||
during the inspection. | |||

2. Action on Previous Inspection Findings
(Closed) Unresolved Item (155/84-15-01): Administrative procedures did
not require a documenteo 10 CFR 50.59 review for temporary modifications
(liftedleadsandjumpers). The inspector verified that the applicable
administrative procedures had been revised to require this review for all
temporary modifications not previously addressed.
3. Program Areas Inspected
a. Maintenance Program
During the most recent SALP period (SALP 5), the licensee was rated
as a Category 2 in the maintenance area. This represented a decline
in performance from the SALP 4 period in which the licensee was rated
a Category 1. In addition, SALP 5 noted that performance continued to
decline during the rating period. The primary reason for the decline
in the SALP rating was the increase in the number of problems requiring
maintenance attention. A particular concern was expressed about those
that could have been prevented by a mnre aggressive PM program (i.e.,
emergency diesel generator problems). Other concerns were the lack of
-

increased management attention to reverse the trend toward more main-
tenance problems and the occasional lack of aggressive action in solving.
maintenance problems. This inspection was augmented to assess the
reasons for the declining performance and any remedial actions being
taken by the licensee to reverse it.
(1) Inspection Results
The inspector reviewed the procedures controlling maintenance
activities, maintenance history files for selected pieces of
equipment, completed maintenance order packages, recent licensee
audits of the maintenance program, the SALP 5 Report, Licensee
Event Reports for 1983-85, and Deviation Reports. The inspector
also interviewed licensee personnel responsible for the mainten-
ance program. Specific observations were as follows:
a_ During the review of completed maintenance orders (M0's),
the inspector noted that the equipment outage requests
(EOR's) were not always completed. Further investigation
indicated that this problem had been identified in the
4 licensee's 1984 audit of maintenance activities and was
incorporated in that report as an observation. During the
licensee's 1985 audit of this area, the problem was found
to be worse and the matter was upgraded to a finding. This
is considered an unresolved item pending NRC review of the
licensee's prompt corrective action (155/85010-01).
b The inspector reviewed the licensee's program for independent
verification of system alignment for removal from and return
'
to service. When protective tagging (for personnel protection)
is required, independent verification of system alignment is
.
performed for removal from service; however, the tagging
system does not provide for independent verification of
l system alignment for return to service. In addition, instru-
mentation and control procedures for calibrations do not
require independent verification of system alignment during
i either removal from or return to service.
3
The inspector discussed this issue with licensee personnel,
l
and they stated that the E0R system does require action to
i determine equipment operability prior to returning it to
'
service. In some cases, this would represent independent
i
verification of system alignment. In other cases, only the
item worked on may be tested and overall system alignment
may not be verified. The Nuclear Operations Department
,
- Standard governing this area was revised during this
inspection to reflect this fact permitting operability
testing to be used for independent verification only when
l
personnel hazards precluded visual verification by a second
- qualified individual. This is considered an unresolved
! item pending NRC review of the revised operating procedures
(155/85010-02).

c- The maintenance staff is experienced and well qualified.
The licensee is generally able to replace experienced
personnel that leave with personnel experienced in their
particular craft. Systems training is provided to the new
personnel. Some skill training is also provided. While no
formal on-the-job training program is used, an apprentice
type program is employed. This provides " hands-on"
experience with plant equipment to new staff members under
the supervision of experienced personnel. An INP0 accredited
maintenance training program is being pursued.
d_ Approximately 4000 maintenance orders (M0s) are processed
each year. At the time of this inspection there were 2
M0s open from 1982 (under review for necessity), 8 from
1983 and approximately 115 from 1984. The backlog appeared
to be reasonable. Preventive maintenance (PM) tasks were
being completed in reasonable agreement with the PM schedule.
~
e To assess the reasons for the declining SALP performance,
the inspector reviewed the examples listed in SALP 5. The
inspector also reviewed LER's for 1983-1985 for other main-
tenance problems which led to reportable conditions.
Specific observations are as follows:
. The problems with the emergency diesel generator
involved a fuel pump shaft failure, loose and pitted
contacts, and failure of a drive coupling to the
engine cooling water pump due to long term wear.
While the diesel engine had recently been overhauled,
the remainder of the system had not been examined or
refurbished. It does appear that a more complete PM
program for this sytem would have prevented these
problems.
. An example of a corrective maintenance situation
that might have been prevented by more aggressive
corrective action involved the recirculating pump seal
leakoff valves (IA60A and IA608). These valves are no
longer used to control seal leakage but remain in a
full open position. In February 1984, the packing in
IA60A failed leading to a high containment radiation
level and a forced outage to repack the valve. During
April 1985, IA60B packing failed leading to another
forced outage to repack that valve. The inspector
reviewed the deviation report associated with IA60A to
determine why IA60B was not repacked after IAG0A
failed. The licensee evaluation of the IA60A failure "
appeared to conclude that the reason for the failure
was that the valve was not backseated. It also noted
that there was some packing left and that the packing
was still pliable. Corrective action included repacking
IA60A, adjusting IA60B packing, and backseating the
valve. A change was also initiated to an operations
valve checklist to routinely ensure these valves were
4
. .
backseated. One item not addressed was anticipated
packing life and establishing a repacking schedule for
these valves. Considering the consequences of packing
failure it would appear prudent to have repacked
IA60B at the same time as IA60A or at least scheduled
it for the next outage. The valves had not been
repacked within the period covered by their machinery
history records (1977 was earliest entry).
(2) Conclusions and Recommendations
There is evidence of weaknesses in the PM program and a lack of
management aggressiveness in upgrading that program based on plant
experience to prevent equipment failures. This is particularly
important considering the age of the plant resulting in the
increased potential for end-of-service-life failures. The
licensee has taken some actions to reduce equipment failures and
increase reliability. Among these are budgeting for replacement
of recorders and transmitters, assessing the replacement of
neutron instrumentation, and the establishment of a PM program
for limitorque operators. However, the following additional
actions should be-considered:
~
a Treat corrective maintenance M0s more like corrective action
documents. Specifically, a review should be performed to
ensure the root cause has been properly identified and an
assessment made to determine if better PM (or other action)
could prevent recurrence. The assessment should include
generic implications and be completed prior to closing the
M0.
-
b A formal evaluation should be made for important plant
equipment to assess the potential for end-of-service life
failures and determine actions necessary to prevent these
failures.
~
c The infonnal assessments of equipment problems currently
performed by the maintenance staff should be documented in
the maintenance history files to ensure their availability
for future assessments.

b. QA/QC Administration
The licensee had recently reorganized resulting in the transfer of
some functions previously performed at the General Offices (GO) to
the Big Rock Point (BRP) site organization. The transfer of these
,
functions necessitated changes to the QA program implementing
l procedures and increased the the BRP QA staff workload. Because of
l NRC concerns relative to the safety impact, the inspector assessed
'
these changes to determine the adequacy of the procedure changes, if
BRP QA personnel were qualified to perform their new responsibilities,
and the impact of the added workload on the ability of the BRP QA
staff to adequately perform their assigned tasks.

(1) Procedure Changes
The top tier implementing documents for the QA program are the
Nuclear Operations Department Standards (N0DS). These standards
specify the organizational responsibilities and requirements
for various subject areas (such as fire protection and plant
security. Due in part to the reorganization, 16 N0DS had been
revised and 15 cancelled. Changes to Administrative Procedures
(APs) (second tier implementing procedures) had not been
completed at the time of this inspection.
a_ Inspection Results
The inspector reviewed the revised and cancelled N0DS and
identified the following concerns:
~
1 The inspector noted that in some cases a revised NODS
referenced a cancelled NODS. In one case the reference
was a "use" reference: N0DS-Q01, (" Corrective Action
and Nonconforming Items") was revised to require QA
Support to trend certain items in accordance with
h0DS-M05 (" Supplier Evaluation and Selection") which
had been cancelled. The inspector asked whether the
requirements of the cancelled N0DS were included in
either the remaining N0DS or the Administrative Proce-
dures (APs). Licensee personnel stated that the
situation had been reviewed and they were satisfied
that all requirements of the cancelled N0DS were
addressed; however, they recognized that cancelled N0DS
were still referenced in both the APs and active N0DS
and could not ensure that there were no other cases in
which the reference was a "use" reference. The
licensee's current plan was to delete references to
the cancelled N0DS in the APs or N0DS when they were
revised for other reasons or at the time of their
biennial review. The inspector was concerned that in
the case where the reference was a "use" reference, as
in the case noted above, this schedule could lead to
the use of uncontrolled documents (cancelled N0Ds) or
the lack of specific direction for performing safety
,
related activities. This is considered an unresolved
item pending further NRC review (155/85010-03).
2_ The NODS provide a convenient reference to applicable
requirements for a specific subject area and provide
a vehicle for G0 level interpretation of these require-
ments. The inspector was concerned that the APs
become more vulnerable to missing requirements in
those areas where a NODS had been cancelled since the
gap between the baseline requirements (Facility
License, NRC approved QA program, etc.) and the APs
had been widened. The preparation of APs becomes more
difficult since the baseline documents must be searched
to identify applicable requirements. The workload

and potential for error are thus increased. The

Matrix (yQARM).
revising
TheitsQARM
Quality Assurance
is currently a twoRequirements
dimensional
matrix relating requirements to implementing procedures.
The revision will add a third dimension relating
subject to requirements. This is considered an open
item pending further NRC review of the adequacy of the
revised QARM for identifying regulatory requirements
relating to subject areas (155/85010-04).
_3_ The N0DS also provide a vehicle for establishing
corporate level policy related to regulatory
requirements in a subject area. The inspector was
concerned that for those subjects covered by the
cancelled N005, this policy making authority had been
effectively transferred to the plant and department
level managers thereby reducing corporate level control.
The licensee stated that this had been discussed
extensively and that corporate level management felt
they had adequate control through the performance
appraisal (MB0) system. .The inspector had no further
questions concerning this subject.
4 Some changes in the revised N0DS, taken collectively,
appeared indicative of weakened controls. Specifically:
. The Corrective Action Review Board (CARB) will
no longer review completed Event Reports (ERs)
or Deviation Reports (DRs). They will review
only the initial reports.
. ERs and DRs will no longer be prioritized.
. Applicability of many N0DS is for safety-related
items only. The issues of "important to safety"
and " reliability" are not addressed.
.
Overdue corrective actions will no longer be
explicitly escalated to higher levels of
management.
.
The Plant Review Committee (PRC) will no longer
review Q-list changes.
. The PRC will no longer review all violations of
procedures required by the Technical
Specifications, only those considered to have
significant safety impact.
Individually, these items may be justified on the basis
of efficiency or line management responsibility or both.
However, as noted above, they do appear indicative of
weakened controls.

.
b_ Conclusions and Recommendations
Based on the observation noted above, the inspector
concluded that the cancellation of some of the NODS
was premature in that the licensee did not adequately
ensure that they were no longer required as a "use"
reference nor provide a fully operational alternative
for efficient identification of requirements for
specific subject areas (eg, QARM). Further, overall
operational controls may have been weakened. Based
on these conclusions, the following actions appear
warranted:
-
1 The licensee should perform an immediate and in
depth review to identify any case where a
cancelled NODS is required as a "use" reference.
In those cases, immediate corrective action
should be taken.
2 The revision to the QARM should be given a high
priority.
3_ The licensee's audit and trending programs
should be augmented on a temporary basis to
focus on these changes to determine if they have
impacted the safety of facility operation.
(2) Site QA Workload and Staff Qualifications
The site QA staff had been assigned new functions previously
performed by the GO QA staff. These functions were:
. Fuel vendor inspections
. Inservice inspection program
. In-line QA reviews for the G0 projects
organization (BRP projects)
. Equipment environmental qualification (EEQ)
program for BRP
. Appendix R (safe shutdown) building for BRP
. Core physics packages for BRP
The lead responsibility for the fuel vendor inspections haa
originally been reassigned to BRP. However, the lead was later
transferred to the Palisades QA staff with BRP providing auditor
support. The EEQ program and Appendix R building were primarily
one time efforts.
The inspector interviewed site QA personnel and reviewed formal
workload projections to determine if the site QA organization
was qualified and adequately staffed to perform these newly
assigned tasks.
8
.. o
a Inspection Results
The inspector made the following specific observations:
1 The workload projection did not include all categories
of work performed by the QA organization. Non-projected
categories included surveillance (approximately 9% of
1983 effort), training, corrective action closecut
reviews, independent assessments, consulting, and
other miscellaneous activities. For those categories
that were projected, the projection for 1985 was based
- on actual manpower expended during the first 6 months
of the year. It included neither the additional effort
required to support the refueling outage scheduled for
late 1985 nor any increase in workload due to the
reorganization which was not fully reflected in the
effort expended during the first six months of 1985.
Site QA personnel felt that the 1985 workload for the
projected categories would be approximately 10% higher
than projected. No projections were available beyond
1985.
The projected categories required an increase of 10%
of the total QA manpower available over that expended
in 1984 in the same categories (adjusted for the
anticipated 10% increase in the 1985 projection for
these categories). An increase in the manpower require-
ments for the non-projected categories of training and
consulting was also experienced during the first 6
months of 1985. The manpower to support the increase
in the projected and non-projected categories was to
'
come from a decrease in the number of surveillances to
'
be performed during 1985. The site QA staff felt that
' those surveillances performed would also contain less
depth than those performed during 1984. Thus, it
l
appeared that an increase of 10% of available manpower
j for projected categories plus an increase in non-pro-
! jected categories plus added refueling outage effort
I was to be recovered by reducing (not eliminating)
'
effort in a category utilizing only 9% of available
manpcwer during 1984. This did not appear feasible
to the inspector.
-
2 The inspector was satisfied that the QA staff was
qualified to perform the newly assigned functions.
However, extra time was required by the staff to
l
familiarize themselves with the specific requirements
l
i
in certain areas such as inservice inspection and fuel
!
vendor audits. Also, one QA staff member (representing
25% of available staff hours) was still in training and
l-
currently qualified to perform only certain categories
of work. This impacted the flexibility in assigning
staff work and increased staff training time.

b Conclusions and Recommendations
Based on the observations noted above, the inspector con-
cluded that workload projection for the site QA staff was
inadequate in that historical data was used to project
workloads in a changed situation and only a portion of the
total workload was projected. Further, the uncertainties
noted above not withstanding, the site QA organization did
appear to be understaffed, at least for the short term.
Based on these conclusions, the following recommendations
are made:
1 A more meaningful workload projection for the site QA
staff should be made. The projection should include
all categories of effort and reflect the full impact
of newly assigned functions. The projection should
also extend beyond 1985.
2_ The site QA staff should be temporarily supplemented
at least until all current staff members are fully
qualified, the 1985 refueling outage is complete, and
the above projection is completed. Any permanent
change in staff level should be based on the
completed projection.

6. Exit Interviews
The inspector met with licensee representatives (denoted in Paragraph 1)
on June 21, 1985 and July 12, 1985, and summarized the purpose, scope, and
findings of the inspection. A final summary of the inspection findings was
presented to the licensee via telecon on July 26, 1985. The licensee
indicated that the inspector had no access to proprietary information
during the inspection.
