2. Followup on Previously Identified Items (Units 1 and 2) | |||
(0 pen) 0 pen Item 313/8017-03: Reactor building purge alarm setpoint. | |||
' The NRC inspector obi;erved a portion of the Unit 1 reactor | |||
building purge conducted'on April 11,'1985,.under permit 1GR 85-20. | |||
Although the Technical Specification gaseous release rate limits | |||
were not approached.or exceeded during this purge, observations | |||
during the purge and subsequent discussions with operations and | |||
radiochemistry personnel indicate that improvements are needed | |||
in the procedures used for conducting a reactor building purge. | |||
Problem areas identified included: | |||
, | |||
. . The alarm setpoint calculated for RE-7400 was 'about.46 times | |||
as high as the highest actual count rate observed during | |||
the purge. | |||
. The special particulate iodine noble gas (SPING) monitor | |||
- | |||
alarm setpoint was about a factor of nine lower than the | |||
calculated concentration-in the reactor building prior to. | |||
the purge. | |||
' | |||
' | |||
. The SPING monitor alarm setpoint was written on the reactor | |||
' | |||
building purge gaseous. release permit in'the space provided | |||
. | |||
for the RE-7400 alarm setpoint. | |||
, . Sample flow to RE-7400 was not lined.up initially, as. | |||
indicated by this instrument's lack of response during the | |||
first segment of- the purge. , | |||

The three LERs concerning ' leaks'in RCP seal pressure sensing lines are | |||
discussed in paragraph 2 of_this. report in conjunction with Open | |||
Item 368/8206-01. | |||
LERs 84-004-00, 84-008-00, and 84-021-00 relate to high'and low steam | |||
generator (S/G) level actuated reactor trips during low feedwater flow | |||
operations. To minimize the number of trips due to this cause, the. | |||
licensee is installing low flow range indication during the current outage | |||
-(2R4). This' indication is provided to assist the operator in controlling | |||
S/G levels during low flow operations. LERs 84-011-00, 84-014-00, | |||
84-020-00, and.84-028-00 relate to reactor trips due to high or low S/G | |||
levels due to equipment malfunction or procedural inadequacies. In each | |||
case, the equipment was repaired and/or. modified or procedure changes | |||
were issued to prevent recurrence. To minimize the number of reactor | |||
trips due to S/G levels, the licensee proposed a Technical Specification | |||
change to reduce the low S/G level trip setpoint from 46 pcecent to | |||
23 percent. This request was approved by the NRC in Amendment 65 to the | |||
' Unit 2 Technical Specifications on April 30, 1985J | |||
No violations or deviations were identified. | |||
4. Followup on IE Information Notices (Units 1 and 2) | |||
' | |||
The NRC, inspector reviewed the licensee actions with respect to IE | |||
information notices' issued during 1984. The review included verification | |||
that all notices issued during 1984 had been received by the licensee, | |||
were distributed to appropriate personnel for an applicability review, and | |||

The licensee has received and reviewed all 1984 information notices. The j | |||
NRC inspector. reviewed the corrective actions taken by the licensee, and | |||
. | |||
it appears-that the corrective actions were appropriate. The NRC | |||
inspector also reviewed a sampling of the implementation of the corrective. | |||
- actions to verify the action taken was in accordance with the results of | |||

2 the documented review. | |||
' | |||
IE Information Notice 84-06, " Steam Binding of Auxiliary Feedwater Pumps," | |||
' was issued on January 25, 1984. The NRC inspector reviewed the licensee's i | |||
. | |||
response'to this issue in more detail in response to a request from the | |||
NRC Office of Inspection and Enforcement. The licensee had reviewed this | |||
issue and performed appropriate corrective action as outlined below: | |||
. Emergency feedwater (EFW) piping is monitored twice per shift by | |||
touch on Unit 1 and once per shift by pyrometer on Unit 2 to detect | |||
back leakage as indicated by a piping temperature increase. | |||
. The Unit 1 EFW operating procedure was revised to check for check | |||
valve back leakage prior to the monthly test of each pump. | |||
. The Unit 2 EFW operating procedure was revised to ensure seating of | |||
the check valves by cycling the stop valves after stopping the pumps | |||
during the monthly tests. | |||
. The EFW operating procedures for both units were revised to provide | |||
guidance on detecting and correcting EFW pump steam binding. | |||
No violations or deviations were identified. | |||
5. Operational Safety Verification (Units 1 and 2) | |||
The NRC inspectors observed control room operations, reviewed applicable | |||
logs, and conducted discussions with control room operators. The | |||
inspectors verified the operability of selected emergency systems, | |||
reviewed tagout records, and verified proper return-to-service of affected | |||
components. Tours of accessible areas of the units were conducted to | |||
observe plant equipment conditions, including potential fire hazards, | |||
fluid leaks, and excessive vibration. In addition, the inspectors ensured | |||
that maintenance requests had been initiated for equipment in need of | |||
maintenance. The inspectors, by observation and direct interview, | |||
verified that the physical security plan was being implemented in | |||
accordance with the station security plan. | |||
During a tour of the Unit 1 auxiliary building, the NRC inspector noted | |||
that NRC-required FD 19 was not shut as it should be. FD 19 is located | |||
between the EFW pump and south piping penetration rooms. The NRC | |||
, | |||
# | |||
n | |||
_. _ _ _ _ _ | |||
. . | |||
-10- | |||
inspector noted that the door was being held open by ventilation air flow. | |||
The door is designed not to latch shut because the door also serves as a | |||
vent path in the event of a high energy line break (HELB) in the south | |||
piping penetration room. The door is normally held shut by an automatic | |||
door closer. Flame and smoke detectors on either side of the fire barrier | |||
were operational as required by Technical Specifications. This item is | |||
unresolved pending a licensee evaluation of how to maintain the door in | |||
the shut position so the effectiveness of FD 19 to contain a fire within | |||
an affected location will not be decreased. (313/8507-01) | |||
During a tour of the Unit 2 auxiliary building, the NRC inspector noted | |||
that FD 210 was being held shut by a latch. FD 210 should not be held | |||
shut because it provides a vent path for an HELB in the lower south piping | |||
penetration room. The NRC inspector reviewed DCP 83-D-2030 and found that | |||
the design change required a door be installed that met the requirements | |||
of 10 CFR Part 50, Appendix R and for an HELB in the penetration room. In | |||
order to meet both requirements, DCP 83-D-2030 provided instructions for | |||
FD 210 to be installed with a door closer to ensure the door remained | |||
shut, but without a latching mechanism so the door would open in the event | |||
of an HELB. The DCP and associated J0 were signed off as completed even | |||
though FD 210 was not installed in accordance with the DCP requirements. | |||
This is an apparent violation. (368/8507-01) | |||
In addition to the required response for the above violation, the licensee | |||
is requested to include a written evaluation of the effect of the latched | |||
door on the HELB analysis for the lower south piping penetration room. A | |||
review of this item will be included in the NRC inspector's followup | |||
inspection of the violation. | |||
The NRC inspectors observed plant housekeeping / cleanliness conditions and | |||
verified implementation of radiation protection controls. The NRC | |||
inspectors walked down the accessible portions of the Unit I high pressure | |||
injection system. The walkdown was performed using Procedure 1104.02 and | |||
Drawing M-231. During the walkdown, minor discrepancies of an editorial | |||
nature were noted. The discrepancies were identified to licensee | |||
personnel. | |||
These reviews and observations were conducted to verify that facility | |||
operations were in conformance with the requirements established under | |||
Technical Specifications,10 CFR, and administrative procedures. | |||
6. Monthly Surveillance Observation (Units 1 and 2) | |||
The NRC inspec.t.rs observed the Technical Specification required | |||
surveillance testing on the Unit 2 emergency diesel generator | |||
(Procedure 2104.36, Supplement II) and verified that testing was performed | |||
in accordance with adequate procedures, that test instrumentation was | |||
calibrated, that limiting conditions for operation were met, that removal | |||

No violations or deviations were identified. | |||
7. Monthly Maintenance Observation (Units 1 and 2) | |||
, | |||
Station maintenance activities of safety-related systems and components | |||
listed below were observed to ascertain that they were conducted in | |||
accordance with approved procedures, Regulatory Guides, and industry codes | |||
' | |||
or standards; and in conformance with Technical Specifications. | |||
The following items were considered during this review: the limiting | |||
conditions for operation were met while components or systems were removed | |||
from service; approvals were obtained prior to initiating the work; | |||
activities were accomplished using approved procedures and were inspected | |||
as applicable; functional testing and/or calibrations were performed prior | |||
to returning components or systems to service; QC records were maintained; | |||
activities were accomplished by qualified personnel; parts and materials | |||
used were properly certified; radiological controls were implemented; and | |||
fire prevention controls were implemented, | |||
i Work requests were reviewed to determine status of outstanding jobs and to | |||
ensure that priority is assigned to safety-related equipment maintenance | |||
which may affect system performance. | |||
' | |||

, '8. LSpent'FuelhoolActivities(Unit 2) | |||
' | |||
IDuring this refueling outage (2R4), the licensee offloaded all fuel ^; | |||
k' ' | |||
- | |||
assembli_es from the core into the spent fuel pool. This was done to | |||
. perform shoulder gap measurements on selected fuel assemblies, remove | |||
control element assemblies (CEA) from spent fuel assemblies into new fuel ' | |||
assemblies,'and replace spent fuel assemblies with new fuel assemblies. ' | |||
i 1, | |||
The' NRC -inspectors observed spent fuel pool activities to verify that | |||
operations'were being conducted in accordance with Procedures.2409.43, | |||
- | |||
"CEA Movement Utilizing CE Equipment"; 2503.01, " Refueling Shuffle"; and | |||
, | |||
2503.03, " Operation of Fuel Handling Equipment." No problems were noted | |||
with the mechanics of handling fuel assemblies in the spent fuel pool.. | |||
During observation of operation of the~ spent fuel pool bridge, the NRC | |||
inspectors noted that the HP area entrance requirements for portions of | |||
the bridge stated that beta protection was required. However, an | |||
individual operating the CEA handling tool within the posted area was not | |||
using the HP-required beta protection (i.e., glasses or goggles). This is | |||
an apparent procedural ~ violation involving failure to comply with the | |||
posted area entrance requirements. (368/8507-02) | |||
9. Emergency Preparedness Exercise Observation (Units 1 and 2) | |||
The NRC inspectors observed the licensee's annual emergency preparedness | |||
exercise held on April 24-25, 1985. The inspectors were located in the | |||
Unit 2 control room and in the technical support center where they | |||
performed observation and participation activities. A detailed discussion | |||
of the NRC' findings during the exercise is provided in NRC Inspection | |||
Report 50-313/85-10; 50-368/85-10. | |||

during the current outage (2R4). The DCPs reviewed were DCP 83-2006, | |||
- | |||
" Service Water Pump Disconnect Switches and Cable Reroute," and | |||
DCP 84-2018, " Service Water Valve Replacement." The following items were | |||
. | |||
verified for these DCPs: | |||
. The changes were reviewed and approved by the licensee in | |||
accordance with 10 CFR Part 50.59 and with licensee procedures. | |||
, | |||
. The implementation of the DCPs was controlled by established | |||
'- | |||
procedures. | |||
. Following implementation, the modified systems were tested in | |||
accordance with approved test procedures. | |||
. The necessary changes to operating procedures were being approved and | |||
were scheduled for implementation prior to plant heatup. | |||
. Operator training on the DCPs was conducted. | |||
. Changes to piping and instrumentation drawings were scheduled to be | |||
issued prior to plant heatup. | |||
. Ignition source permits were issued when required. | |||
. For DCP 83-2006, the licensee had reviewed and approved the seismic | |||
qualification report for the new disconnect switch cabinets. | |||
. Field change notices to the DCPs were used to document and control | |||
design revisions found to be needed after DCP implementation was | |||
started. | |||
. Checks were performed at various times during installation to verify | |||
that the change was being performed in accordance with the DCP. | |||
No violations or deviations were identified. | |||
11. Near-Term Inspection Followup to GL 83-28 (Units 1 anJ 2) | |||
GL 83-28, " Required Actions Based on Generic Implication of Salem ATWS | |||
t Events," was issued by the NRC on July 8, 1983. GL 83-28 required each | |||
licensee to address the near- and long-term programs associated with post- | |||
trip review, equipment classification, vendor interface, and maintenance | |||
programs for safety-related components within safety-related systems. | |||

2. Followup on Previously Identified Items (Units 1 and 2)
(0 pen) 0 pen Item 313/8017-03: Reactor building purge alarm setpoint.
' The NRC inspector obi;erved a portion of the Unit 1 reactor
building purge conducted'on April 11,'1985,.under permit 1GR 85-20.
Although the Technical Specification gaseous release rate limits
were not approached.or exceeded during this purge, observations
during the purge and subsequent discussions with operations and
radiochemistry personnel indicate that improvements are needed
in the procedures used for conducting a reactor building purge.
Problem areas identified included:
,
. . The alarm setpoint calculated for RE-7400 was 'about.46 times
as high as the highest actual count rate observed during
the purge.
. The special particulate iodine noble gas (SPING) monitor
-
alarm setpoint was about a factor of nine lower than the
calculated concentration-in the reactor building prior to.
the purge.
'
'
. The SPING monitor alarm setpoint was written on the reactor
'
building purge gaseous. release permit in'the space provided
.
for the RE-7400 alarm setpoint.
, . Sample flow to RE-7400 was not lined.up initially, as.
indicated by this instrument's lack of response during the
first segment of- the purge. ,

3. LicenseeEventReport(LER) Followup (U, nit}2)
~
Through direct observation, discussions with. licensee' personnel, and
review of records, the following Unit 2 event' reports were reviewed to '
determine that reportability requirements were fulfilled, inmediate
e corrective action was accomplished, and corrective action to prevent-
recurrence has been accomplished in accordance with Technical
-Specifications.
82-017/03L'-0 'RCP seal pressure sensing line leak

84-011-00 Reactor trip on high steam generator level
84-014-00 Reactor trip on high steam' generator level
84-020-00 Reactor trip on high steam generator level
84-021-00 Reactor trip on high steam generator level
84-028-00 Reactor' trip on low steam generator level
The three LERs concerning ' leaks'in RCP seal pressure sensing lines are
discussed in paragraph 2 of_this. report in conjunction with Open
Item 368/8206-01.
LERs 84-004-00, 84-008-00, and 84-021-00 relate to high'and low steam
generator (S/G) level actuated reactor trips during low feedwater flow
operations. To minimize the number of trips due to this cause, the.
licensee is installing low flow range indication during the current outage
-(2R4). This' indication is provided to assist the operator in controlling
S/G levels during low flow operations. LERs 84-011-00, 84-014-00,
84-020-00, and.84-028-00 relate to reactor trips due to high or low S/G
levels due to equipment malfunction or procedural inadequacies. In each
case, the equipment was repaired and/or. modified or procedure changes
were issued to prevent recurrence. To minimize the number of reactor
trips due to S/G levels, the licensee proposed a Technical Specification
change to reduce the low S/G level trip setpoint from 46 pcecent to
23 percent. This request was approved by the NRC in Amendment 65 to the
' Unit 2 Technical Specifications on April 30, 1985J
No violations or deviations were identified.
4. Followup on IE Information Notices (Units 1 and 2)
'
The NRC, inspector reviewed the licensee actions with respect to IE
information notices' issued during 1984. The review included verification
that all notices issued during 1984 had been received by the licensee,
were distributed to appropriate personnel for an applicability review, and

.
"
The licensee has received and reviewed all 1984 information notices. The j
NRC inspector. reviewed the corrective actions taken by the licensee, and
.
it appears-that the corrective actions were appropriate. The NRC
inspector also reviewed a sampling of the implementation of the corrective.
- actions to verify the action taken was in accordance with the results of
2 the documented review.
'
IE Information Notice 84-06, " Steam Binding of Auxiliary Feedwater Pumps,"
' was issued on January 25, 1984. The NRC inspector reviewed the licensee's i
.
response'to this issue in more detail in response to a request from the
NRC Office of Inspection and Enforcement. The licensee had reviewed this
issue and performed appropriate corrective action as outlined below:
. Emergency feedwater (EFW) piping is monitored twice per shift by
touch on Unit 1 and once per shift by pyrometer on Unit 2 to detect
back leakage as indicated by a piping temperature increase.
. The Unit 1 EFW operating procedure was revised to check for check
valve back leakage prior to the monthly test of each pump.
. The Unit 2 EFW operating procedure was revised to ensure seating of
the check valves by cycling the stop valves after stopping the pumps
during the monthly tests.
. The EFW operating procedures for both units were revised to provide
guidance on detecting and correcting EFW pump steam binding.
No violations or deviations were identified.
5. Operational Safety Verification (Units 1 and 2)
The NRC inspectors observed control room operations, reviewed applicable
logs, and conducted discussions with control room operators. The
inspectors verified the operability of selected emergency systems,
reviewed tagout records, and verified proper return-to-service of affected
components. Tours of accessible areas of the units were conducted to
observe plant equipment conditions, including potential fire hazards,
fluid leaks, and excessive vibration. In addition, the inspectors ensured
that maintenance requests had been initiated for equipment in need of
maintenance. The inspectors, by observation and direct interview,
verified that the physical security plan was being implemented in
accordance with the station security plan.
During a tour of the Unit 1 auxiliary building, the NRC inspector noted
that NRC-required FD 19 was not shut as it should be. FD 19 is located
between the EFW pump and south piping penetration rooms. The NRC
,
n
_. _ _ _ _ _
. .
-10-
inspector noted that the door was being held open by ventilation air flow.
The door is designed not to latch shut because the door also serves as a
vent path in the event of a high energy line break (HELB) in the south
piping penetration room. The door is normally held shut by an automatic
door closer. Flame and smoke detectors on either side of the fire barrier
were operational as required by Technical Specifications. This item is
unresolved pending a licensee evaluation of how to maintain the door in
the shut position so the effectiveness of FD 19 to contain a fire within
an affected location will not be decreased. (313/8507-01)
During a tour of the Unit 2 auxiliary building, the NRC inspector noted
that FD 210 was being held shut by a latch. FD 210 should not be held
shut because it provides a vent path for an HELB in the lower south piping
penetration room. The NRC inspector reviewed DCP 83-D-2030 and found that
the design change required a door be installed that met the requirements
of 10 CFR Part 50, Appendix R and for an HELB in the penetration room. In
order to meet both requirements, DCP 83-D-2030 provided instructions for
FD 210 to be installed with a door closer to ensure the door remained
shut, but without a latching mechanism so the door would open in the event
of an HELB. The DCP and associated J0 were signed off as completed even
though FD 210 was not installed in accordance with the DCP requirements.
This is an apparent violation. (368/8507-01)
In addition to the required response for the above violation, the licensee
is requested to include a written evaluation of the effect of the latched
door on the HELB analysis for the lower south piping penetration room. A
review of this item will be included in the NRC inspector's followup
inspection of the violation.
The NRC inspectors observed plant housekeeping / cleanliness conditions and
verified implementation of radiation protection controls. The NRC
inspectors walked down the accessible portions of the Unit I high pressure
injection system. The walkdown was performed using Procedure 1104.02 and
Drawing M-231. During the walkdown, minor discrepancies of an editorial
nature were noted. The discrepancies were identified to licensee
personnel.
These reviews and observations were conducted to verify that facility
operations were in conformance with the requirements established under
Technical Specifications,10 CFR, and administrative procedures.
6. Monthly Surveillance Observation (Units 1 and 2)
The NRC inspec.t.rs observed the Technical Specification required
surveillance testing on the Unit 2 emergency diesel generator
(Procedure 2104.36, Supplement II) and verified that testing was performed
in accordance with adequate procedures, that test instrumentation was
calibrated, that limiting conditions for operation were met, that removal

<results. conformed with Technical Specifications and procedure
requirements, that test results were reviewed by personnel other than the
individual directing the test,,and that any deficiencies identified during
-
the testing were properly reviewed and resolved by' appropriate management
personnel.
The inspectors also witnessed portions of the following test activities:
,
. Unit 2 class 1E battery charger (2032) load test (Procedure 2403.53)
. Unit 1 low pressure injection pump monthly test (Procedure 1104.04,
4 Supplement I)
. Unit 2 visual inspection of mechanical snubbers (Procedure 1406.36)
. Unit 2 functional testing of mechanical snubbers (Procedure 1406.40) >
. Unit 2 engineered safeguards features relay testing (JO 71748)
No violations or deviations were identified.
7. Monthly Maintenance Observation (Units 1 and 2)
,
Station maintenance activities of safety-related systems and components
listed below were observed to ascertain that they were conducted in
accordance with approved procedures, Regulatory Guides, and industry codes
'
or standards; and in conformance with Technical Specifications.
The following items were considered during this review: the limiting
conditions for operation were met while components or systems were removed
from service; approvals were obtained prior to initiating the work;
activities were accomplished using approved procedures and were inspected
as applicable; functional testing and/or calibrations were performed prior
to returning components or systems to service; QC records were maintained;
activities were accomplished by qualified personnel; parts and materials
used were properly certified; radiological controls were implemented; and
fire prevention controls were implemented,
i Work requests were reviewed to determine status of outstanding jobs and to
ensure that priority is assigned to safety-related equipment maintenance
which may affect system performance.

'
IDuring this refueling outage (2R4), the licensee offloaded all fuel ^;
k' '
-
assembli_es from the core into the spent fuel pool. This was done to
. perform shoulder gap measurements on selected fuel assemblies, remove
control element assemblies (CEA) from spent fuel assemblies into new fuel '
assemblies,'and replace spent fuel assemblies with new fuel assemblies. '
i 1,
The' NRC -inspectors observed spent fuel pool activities to verify that
operations'were being conducted in accordance with Procedures.2409.43,
-
"CEA Movement Utilizing CE Equipment"; 2503.01, " Refueling Shuffle"; and
,
2503.03, " Operation of Fuel Handling Equipment." No problems were noted
with the mechanics of handling fuel assemblies in the spent fuel pool..
During observation of operation of the~ spent fuel pool bridge, the NRC
inspectors noted that the HP area entrance requirements for portions of
the bridge stated that beta protection was required. However, an
individual operating the CEA handling tool within the posted area was not
using the HP-required beta protection (i.e., glasses or goggles). This is
an apparent procedural ~ violation involving failure to comply with the
posted area entrance requirements. (368/8507-02)
9. Emergency Preparedness Exercise Observation (Units 1 and 2)
The NRC inspectors observed the licensee's annual emergency preparedness
exercise held on April 24-25, 1985. The inspectors were located in the
Unit 2 control room and in the technical support center where they
performed observation and participation activities. A detailed discussion
of the NRC' findings during the exercise is provided in NRC Inspection
Report 50-313/85-10; 50-368/85-10.

during the current outage (2R4). The DCPs reviewed were DCP 83-2006,
-
" Service Water Pump Disconnect Switches and Cable Reroute," and
DCP 84-2018, " Service Water Valve Replacement." The following items were
.
verified for these DCPs:
. The changes were reviewed and approved by the licensee in
accordance with 10 CFR Part 50.59 and with licensee procedures.
,
. The implementation of the DCPs was controlled by established
'-
procedures.
. Following implementation, the modified systems were tested in
accordance with approved test procedures.
. The necessary changes to operating procedures were being approved and
were scheduled for implementation prior to plant heatup.
. Operator training on the DCPs was conducted.
. Changes to piping and instrumentation drawings were scheduled to be
issued prior to plant heatup.
. Ignition source permits were issued when required.
. For DCP 83-2006, the licensee had reviewed and approved the seismic
qualification report for the new disconnect switch cabinets.
. Field change notices to the DCPs were used to document and control
design revisions found to be needed after DCP implementation was
started.
. Checks were performed at various times during installation to verify
that the change was being performed in accordance with the DCP.
No violations or deviations were identified.
11. Near-Term Inspection Followup to GL 83-28 (Units 1 anJ 2)
GL 83-28, " Required Actions Based on Generic Implication of Salem ATWS
t Events," was issued by the NRC on July 8, 1983. GL 83-28 required each
licensee to address the near- and long-term programs associated with post-
trip review, equipment classification, vendor interface, and maintenance
