- 1.6 SIGNIFICANT DESIGN INFORMATION 1.6~.1 REACTOR INTEGRITY Reactor Pressure Vessel (RPV)
With the present fuel type and mhnagement policy, Unit 1 is expected to reach a 40-year RPV life. On this unit, the fuel type ;
and management policy have been modified to make that RPV life !
. r l'
4 span possible. Presently, a program is evolving for RPV life.
extension beyond the projected 40 years, potentially to 60 years, via a flux reduction program. A flux reduction program has started with the addition of eight absorbers in core corner positions, performance of vessel fluence calculations, and determination of an optimum power profile for each core load. I Calculations using current methodology and uncertainty predict a -
significant RPV life extension, but not to 60 years. Excore dostmetry installed for the current cycle [with planned removal in '
Octoberi 1994) will be used to reduce calculation uncertainty.
~.
Due to different design.and construction characteristics, Unit 2 RPV life expectancy exceeds 60 years. Low leakage core designs are now used for economic reasons, however the low leakage designs provide even greater life expectancy. .
Reactor Coolant Pressure Boundarv !
On this CE plant, ECCS-to-RCS injection points are isolated by at least two check valves and one closed MOV. High pressure safety injection (HPSI), low pressure safety. injection (LPSI), and containment spray (CS) pumps' common containment sump suctions are isolated from the containment sump by one closed MOV in ,
conjunction with a closed seismic piping system. The CS headers I are isolated from containment by one closed MOV and a check valve ;
in conjunction with a closed seismic piping system. CVCS has the j s' normal complement of two automatic actuation isolation valves. l 1.6.2 REACTOR SHUTDOWN Reactor Protection System The reactor protection system provides protection for the reactor fuel and its cladding by providing automatic roactor shutdowns (8
,i trip's) based on input from reactor power, reactor coolant pressure, coolant temperature, coolant flow, steam generator 3
pressure, and containment pressure. The RPS is a redundant four-channel system that operates on a two-out-of-four logic.
ATWS Protection
+
ATWS protection, outside the normal reactor protection system, is initiated via the ESF pressurizer pressure signal. It actuates by o,'ening contactors in the output of the CEA MG sets, thereby interrupting control element assembly power at its source. This protection'has been installed on both units per CE, the NSSS, ;
recommendations.
]
, Remote Shutdown Facilities These facilities are located in the switchgear rooms beneath each I unit's control room.

Auxiliary Feedwater System f There are two motor-driven pumps on each unit with 100 percent
? capacity per pump. There.is one steam-driven pump on each~ unit i with 200. percent capacity. Any of the three pumps can inject to
, either steam generator. Automatic initiation and faulted steam generator protection are provided by each unit's Auxiliary ,

] In each unit,.there are two HPSI pumps and two LPSI pumps with no
" i-unit-to-unit cross-connections. One pump of each type per unit will handle a postulated LOCA. The LPSI pumps also provide decay L heat removal as required when the unit is shut down. t i '
i Decay Heat Removal As indicated above, the LPSI pumps also provide decay heat removal as required when the unit is shut down by taking suction from the
,I RCSi(hot legs), passing the fluid through the shutdown cooling heat exchangers, and returning it to the RCS (cold legs). The
+
heat removing medium is CCW - discussed in section l.7.6 below.
Shutdown cooling flow path overpressure protection is provided by automatic isolation valves and various relief valves in the system.
1.6.4 CONTAINMENT Pressure Control / Heat Removal
, There_Are two containment spray pumps.and four containment fan 4
coolers available per unit to suppress' pressure spikes and cool
, the containment. One CS pump and two fan coolers will handle a postulated LOCA. There are no unit-to-unit cross-connections.
This engineered' safety feature is automatically started by ESFAS.

Hydroaen Control Containment hydrogen control post-LOCA is accomplished on each
, unit by two trains of hydrogen recombiners located on the operating deck inside containment. By elevating, in a controlled manner, the temperature of containment atmosphere flowing through the recombiner, the recombiner units recombine hydrogen and oxygen to form water, thus preventing the buildup of hydrogen to potentially explosive levels.

1.6.5 ELECTRICAL POWER -
Offsite AC The station switchyard is connected to the transmission system by three independent 240 KV lines that share a right of way and interconnect with FPL's grid on the mainland approximately 10 4 miles West of the plant site. There are two independent offsite power feeds from the station switchyard to the emergency busses.
Onsite AC l Onsite AC power is provided by four EDGs (two per unit). EDGs are ,
independent of other plant systems except vital DC power for i control of starting. A Station Blackout (S80) cross connection is i installed and tested. This cross-connection serves the emergency !
busses directly and reduces cross-connect time to less than 15 !
minutes.
! DC Power ;
1
.Two trains of vital batteries per unit have been routinely tested for four-hour DC load profiles. Recently, due to cell replacement, they have been tested for three-hour battery capacity instead. The battery capacity test is harsher than the load profile test. There are four normal chargers per unit with swing
< chargers available for service. Non-safety batteries can be
- j cross-connected'to the safety-related swing bus if needed.
Instrumentation Power r Each unit has four inverters, two powered from each vital DC train, that provide four trains of instrumentation power.
Station Blackout Resolution-Status I
Unit 2 is a four-hour "0C coping" plant per the original license while Unit 1 is subject to the station blackout (580) rule.of 10 CFR 50763 requiring additional licensee action (unit-to-unit cross-connect of 4160V bus).

l 1.6.6 SAFETY-RELATED COOLING WATER SYSTEMS
. \
Intake Coolina Water (Service Water) i Intake cooling water (ICW)'for each unit originates in a common .
canal called the Intake Canal. The canal level. varies with the I tides since it is filled by a level difference between the l Atlantic Ocean and the canal. One 16-foot and two 12-foot diameter pipes pass under the beach to connect the ocean and 1 canal. The intake pipe ends in the Atlantic ~are covered by intake structures (rebuilt in 1991) intended to limit flow velocities,- .
particularly vertical velocity, to reduce marine life entrapment.
After use, ICW returns to the ocean through a Discharge Canal and under-beach pipes.
j Each unit has two trains of ICW plus a swing pump that can be aligned to either train electrically and physically. The licensee
< has converted the deep draft ICW pumps from externally (water).
lubricated to self-lubricated to increase reliability of the t
lubrication water source. The 100 percent (each) capacity pumps take suction from the intake canal via a canal intake structure using traveling screen debris protection. The intake canal structures adjacent to the ICW pump suctions are continuously injected with a hypochlorite solution to reduce marine growth in -
} the associated piping and heat exchangers. Commencing 3/92,
. periodic injection of a clasicide at the intake structures, if', primarily to control marine growth affecting the turbine condensers, has also somewhat reduced marine growth affecting the j, ICW system, i4 The'ICW pumps move water through two trains of her.t exchangers
- that cool component cooling water (CCW) and two trains of heat
'exchangers that cool main turbine cooling water. During a-
- . - post.ulated accident, water. flow isolates from the turbine cooling
_ heat exchangers. The discharge from the heat exchangers returns via,the discharge canal to the ocean.
,l -
Increases in debris and silt in the' heat exchangers during 1993 indicated that the intake canal needed dredging.
As of September 1993, the utility was routinely cleaning
- main condenser waterboxes at reduced power and obtaining necessary dredging permits from the state and Corps of ..
Engineers. l The canal was dredged in December 1993 and January 1994 with immediate results.of reduced waterbox fouling.
Closed Coolino Water Systems Each unit has two trains of Component Cooling Water (CCW). The arrangement of two pumps and a swing pump mimics the ICW system.

8 The swing pump can be aligned to either train. The 100 percent (each) capacity pumps drive water through the CCW/ICW heat exchangers and then on to the heat loads, mainly the containment fan coolers and the shutdown cooling (decay heat) heat.exchangers
, (which also can operate as containment spray heat exchangers).
Additionally, CCW cools a variety of bearings, seals, and oil coolers for the HPSI, LPSI, and CS pumps. A non-safety-related-portion of the CCW system cools reactor coolant pump seals and the spent fuel pool. This section isolates upon engineered safety features actuation.
1.6.7 SPENT FUEL STORAGE Wet storage capability exists up to the year 2002 (Unit 2) and .
2007 (Unit 1).
i 1.6.8 INSTRUMENT AIR SYSTEM Instrument air compressors and driers, installed several years ago on each unit, provide all instrument air for Unit 2 and all but containment air for Unit 1. These have increased instrument air reliability. Unit I also has instrument air compressors inside containment. ,
1.6.9 STEAM GENERATORS
- Each unit has two large steam generators (SGs) rather than the l three or four usually seen. The licensee has begun to focus on a Unit 1 SG replacement in 1997. The SGs are under construction at the B&W Canada shops and a site organization is functioning.

V
s w .
12 Since July 1995, there has been a series of events that led to
. questioning the plants overall performance. These have included: a Unit 1 turbine trip due.to procedural weakness, operator performance and
,a supervisory oversight; the attempt to restage an RCP seal using
- inadequate and inappropriate procedural guidance which led to the failure of the second and third stage seals, a main steam isolation signal due to inappropriate operator response, an inadvertent reactor q protection system' actuation due to inattention to detail by an operator, !
j , both pressurizer relief valves being inoperable due to incorrect 4 assembly during a refueling outage, an inoperable shutdown cooling -
I f relief valve due to incorrect setpoint margins (a generic problem '
involving several valves), the spray down of containment due to an 4 inadequate procedure and operator error coupled with an existing
- , operator-work-around. These and several other recent deficiencies
- j involving weak procedures, a general lack of procedural compliance, l[ equipment failures, and personnel errors clearly indicate that the plants past_high level of performance has declined. Both units were shutdown on August 1, 1995, for Hurricane Erin. Unit 2 immediately restarted but Unit I remained shutdown. The above problems have led to 4
several plant management' changes, an overall evaluation of the recent
-plant problems by a plant requested independent assessment team and a root cause evaluation by the NRC. In a meeting with the NRC on August ,
29, 1995, the licensee committed to use the results of the independent -
assessment team to develop an action plan for improvement. ]
'1 Plant Ooerations 2
1 Summary of Previous Assessment Within the current SALP cycle, previous assessments have noted a l- potential decline in Operations' performance. Noted indicators
, included five reactor trips in the first six months of the cycle.
t No-rosmon root causes were. identified. Operator actions with
! !: regard to the noted trips were generally good. Two entries into f reduced inventory operations during the Unit 2 outage were noted R
~
as excellent. Procedural weaknesses which indicated'a lack of j.'
rigor in the review process were noted, as was_the fact that temporary changes to procedures were on the increase (indicating increasing' attention to procedural adequacy).
Management activities in response to the increase in operational events was determined to be strong, with an increase in overall focus directed at plant operations. The corrective action:
program was enhanced, consolidating several programs into one which involves daily management reviews of all documented conditions.
The previous _ assessments concluded that Operations remained strong in.the current period, that management actions were aggressive in dealing with identified weaknesses,' and that increased attention to procedural adequacy may be warranted.

activities had not abated. Strong performance had been noted in the support of the Unit 2 outage, and housekeeping and plant preservation activities were' deemed good.
t Last Six Months 1
During the past six months, 24 maintenance activities were
- observed in varying levels of depth. One violation involving the installation of incorrect size motor overload heater was identified.. Three potential violations involving, inadequate surveillance, inadequate post maintenance tests, and two inoperable PORV are currently being evaluated. Two non-cited violations involving inadequate control on jumpers were identified. Workers were found to be well skilled and trained overall. Problems have s' been noted in procedural adequacy and use.
Twenty-two surveillance activitie's were observed. Two non-cited violations involving the failure to perform surveillance within specified time limits were identified.
These were the result of a weak surveillance tracking system.
Strengths
~
q The licensee continues to use and improve'on their online maintenance procedure and implementation.
Overall maintenance activities performed under this program were well planned and executed. The craft work force is motivated and overall skill level is high. The licensee has completed the development of 4
their maintenance rule and it will be in place and operating by the end of September. The predictive maintenance-crganization continues to provide early indication of pending failure and assists in root i
cause evaluation of equipment failures.
Weaknesses V
Weaknesses have been identified in the following areas:
' !n f
.9
~
15
- Procedural adequacy
- Procedural complianse
- Installation of incorrect parts.-
- Personnel errors in work performance
- Surveillance tracking system
= Equipment failures
- Control of lifted leads / jumpers
= Communications Conclusion Maintenance performance has declined. Equipment failures have impacted plant operation. Craft personnel are not identifying and correcting procedural deficiencies and are using procedures as general guidance. Individual and group performance is generally excellent for high visibility jobs, j but attention to detail appears to lapse on routine work.

i~ Summary of Previous Assessment The previous assessments for this SALP cycle concluded that ,
engineering was generally strong. Good support of the Unit -
! 2 outage was noted, as was good QA with respect to fuel fabrication and receipt inspection.
! Last Six Months o
i Engineering at St. Lucie remains strong. The trend in the 1 number of issues over the past two quarters has gone down.
However, a number of issues in the area organizational / program communication have arisen. Recently.
-. there was an upward turn in the number of engineering issues l{-
' during the recent shut down. Those issues are being inspected. In the aggregate, St. Lucie Engineering has provided valuable support to Operations and Maintenance
].
l; throughout the past year.
il~
Conclusion Engineering continues to perform well. No weaknesses have l: been identified in this functional area. -

, NRR ASSESSMENT FOR ST. LUCIE i
September 1995 .
i CURRENT ISSUES
-Seismic qualification of electrical and mechanical equipment (GL 87-02, USI A-46) issue on Unit 1 is still not resolved. The staff. issued a letter in early 1994 providing a general framework of criteria which would resolve this issue. FPL responded in May 1994 restating their previous position and stating that they j believe that further NRC requests for work, evaluations, or plant changes would provide no additional safety benefit to their nuclear facilities. The staff is considering performing a backfit analysis to determine the possibility of ordering ;
FPL to implement additional actions or accept the licensees position. A third alternative being evaluated is performance of a site inspection to determine if any safety-significant issues exist in the areas of disagreement.
-Unit I will be replacing steam generators in 1997. The licensee is well into ,
planning for the event.
I
-An alternative approach to the resolution of the Thermo-Lag issue was proposed by I i FPL, however, the staff did not pursue review of this performance based approach
, based on Commission direction of this issue. The licensee is scheduled to submit to I the staff by.early November 1994 a schedule and method for resolution of the Thermo-
, Lag issue.
-The plant continues to perform well. The latest SALP evaluation had ratings of I ;
in all categories. '
