REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity
1R04 Equipment Alignment
.1 Partial System Walkdowns
a. Inspection Scope
The inspectors performed walkdowns of the critical portions of the selected trains to verify correct system alignment. The inspectors reviewed plant documents to determine the correct system and power alignments, and the required positions of select valves and breakers. The inspectors verified that the licensee had properly identified and resolved equipment alignment problems that could cause initiating events or impact mitigating system availability. The inspectors verified the following four partial system alignments in system walkdowns using the listed documents:
C Nuclear service water (SW) pumps SWP-1B and SWP-1C systems, using Operating Procedure OP-408, Nuclear Services Cooling System, while SWP-1A was out of service for planned maintenance; C Control complex chilled water system (CHHE-1A), using OP-409, Plant Ventilation System, while chiller CHHE-1B was out of service for planned maintenance; C Makeup (MU) system pumps MUP-1A, MUP-1B, and MUP-1C, using Operating Procedure OP-402, Makeup and Purification System, and raw water (RW)pumps RWP-2A, RWP-2B, RWP-3A, and RWP-3B, using OP-408, Nuclear Services Cooling System, while the alternate AC emergency diesel generator (EGDG-1C) and feedwater pump (FWP-7) were both out of service for maintenance; and C A train decay heat closed cycle cooling (DC) and decay heat removal (DHR)systems, using OP-404, Decay Heat Removal System, while the B train emergency core cooling system (ECCS) was out of service for maintenance.
b. Findings
No findings of significance were identified.
.2 Complete System Walkdown
a. Inspection Scope
The inspectors conducted one detailed walkdown/review of the alignment and condition of the emergency diesel generator EGDG-1B and its associated 4160V engineered safeguards (ES) Bus 3B. The inspectors utilized licensee procedures, as well as licensing and design documents to verify that the system (i.e., pump, valve, and electrical) alignment was correct. During the walkdown, the inspectors also verified that:
the pumps, valves and piping associated with the diesel did not exhibit leakage that would impact its function, major portions of the systems and components were correctly labeled, hangers and supports were installed and functional; and essential support systems were operational. In addition, pending design and equipment issues were reviewed to determine if the identified deficiencies impacted the systems functions. A review of open nuclear condition reports (NCRs) was performed to verify that the licensee had appropriately characterized and prioritized equipment problems for resolution in corrective action program. Documents reviewed are listed in the attachment.
b. Findings
No findings of significance were identified.
1R05 Fire Protection
Fire Protection Walkdowns
a. Inspection Scope
The inspectors walked down accessible portions of the plant to assess the licensees implementation of the fire protection program. The inspectors checked that the areas were free of transient combustible material and other ignition sources. Also, fire detection and suppression capabilities, fire barriers, and compensatory measures for fire protection problems were verified. The inspectors checked fire suppression and detection equipment to determine whether conditions or deficiencies existed which could impair the function of the equipment. The inspectors selected the areas based on a review of the licensees probabilistic risk assessment. The inspectors also reviewed the licensees fire protection program to verify the requirements of Final Safety Analysis Report (FSAR) Section 9.8, Plant Fire Protection Program, were met. Documents reviewed are listed in the attachment. The inspectors toured the following nine areas important to reactor safety:
- Emergency feed pump (EFP-3) building
- Intermediate building 95' elevation, EFP-1 and EFP-2 areas
- Emergency feed tank (EFT-2) building and the alternate AC emergency diesel generator EGDG-1C building
- FWP-7 area
- Cable spreading room
- Makeup pump cubicles
- Control complex chiller room
- Auxiliary building 95' level sea water room
- Control complex B train ES 4160 V switchgear room
b. Findings
No findings of significance were identified.
1R11 Licensed Operator Requalification Program
Resident Inspector Quarterly Review
a. Inspection Scope
On August 8, 2007, the inspectors observed one separate licensed operating training activity associated with a loss of decay heat removal during shutdown conditions. The inspectors observed a classroom training session associated with a loss of reactor coolant system coolant (lesson OPS-5-114) and operator response and actions for the Crystal River, Unit 3 simulator training session, LOR-1-05. The simulator session involved a loss of the operating decay removal pump and required the crew to use plant abnormal procedure AP-404, Loss of Decay Heat Removal.
The inspectors specifically evaluated the following attributes related to crew performance:
- Clarity and formality of communication including crew briefings
- Ability to take timely action to safely control the unit
- Prioritization, interpretation, and verification of alarms
- Correct use and implementation of off-normal procedures; and emergency plan implementing procedures
- Control board operation and manipulation, including operator actions
