  • auxiliary building sea water room

b. Findings

No findings were identified.

.2 Adverse Weather Protection: External Flooding

a. Inspection Scope

The inspectors performed an inspection of the external flood protection features for Crystal River, Unit 3. The inspectors reviewed the Final Safety Analysis Report (FSAR) Chapter 2.4.2.4, Facilities Required for Flood Protection, which depicts the design flood levels and protection areas containing safety-related equipment, to identify areas that may be affected by external flooding. As part of NRC temporary instruction (TI) 2515/183, Follow-up to the Fukushima Daiichi Nuclear Station Fuel Damage Event, the inspectors accompanied maintenance personnel and observed their inspections of various watertight doors and flood gates in the auxiliary building as well as their inspection of the diesel fuel tank (DFT) 1B vent stack and manway covers. The inspectors conducted a general site walkdown of all external areas of the plant including the turbine building, auxiliary building, and berm to ensure that flood protection measures were erected in accordance with design specifications.

Procedure EM-220, Violent Weather, was checked to verify that adequate measures were planned or established to protect against external flooding due to hurricanes.

Specific plant attributes that were checked included: structural integrity, sealing of penetrations below the design flood line, and adequacy of watertight doors between flood areas. The documents reviewed are listed in the attachment.

b. Findings

No findings were identified.

.3 Adverse Weather Protection: Offsite and Alternate AC Power System Readiness

a. Inspection Scope

The inspectors evaluated the summer readiness of both the offsite and onsite alternate AC power systems. The inspectors walked down the safety-related emergency diesel generators (EGDG-1A, 1B), non-safety-related emergency diesel generator (EGDG-1C), and the safety-related diesel driven emergency feedwater pump (EFP-3) to verify they would be available during a loss of offsite power event.

The inspectors performed a walk down of the switchyard with plant personnel to verify the material condition of the offsite power sources was adequate. Open work orders (WOs) for the offsite and onsite AC power systems were reviewed to ensure degraded conditions were properly addressed. The inspectors verified that licensee and transmission system operator procedures contained communication protocols addressing the exchange of appropriate information when issues arise that could impact the offsite power system. The inspectors verified that no equipment or operating procedure changes have occurred since the last performance of this inspection that would potentially affect operation or reliability of the offsite or onsite AC power systems. The documents reviewed are listed in the attachment.

b. Findings

No findings were identified.

1R04 Equipment Alignment

.1 Partial Equipment 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 two partial system alignments in system walkdowns using the listed documents:

  • B train 4160 and 480 Volt Engineering Safeguard (ES) Buses and B train 480 Volt motor control centers, using OP-700A, 6900, 4160, and 480 Volt AC Buses; and OP-700B, 480 Volt AC Motor Control Centers, while EGDG-1A was out of service for planned maintenance

No findings 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-1A and its associated 4160 volt engineered safeguards (ES) Bus 3A. 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 work orders and 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 were identified.

1R05 Fire Protection

Fire Area 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 FSAR Section 9.8, Plant Fire Protection Program, were met. Documents reviewed are listed in the attachment. The inspectors toured the following five areas important to reactor safety:

  • vital battery inverter rooms
  • A and B train 480 volt engineering safeguards (ES) switch gear rooms
  • intermediate building 119 elevation
  • offsite power transformer, backup ES service transformer, and main step-up transformer areas

b. Findings

No findings were identified.

1R06 Flood Protection Measures

Internal Flood Protection

a. Inspection Scope

The inspectors reviewed the Crystal River Unit 3, FSAR, Chapter 2.4.2.4, Facilities Required for Flood Protection, and the Crystal River Unit 3 Design Basis Documents that depicted protection for areas containing safety-related equipment to identify areas that may be affected by internal flooding. As part of NRC temporary instruction (TI) 2515/183, Follow-up to the Fukushima Daiichi Nuclear Station Fuel Damage Event, the inspectors accompanied engineering and observed their inspections on the circulating water pump and raw water pump encapsulation sleeve gaps and independently confirmed the licensees conclusions. The inspectors walked down the auxiliary building 95 foot elevation sea water room area, and the turbine building 95 foot and 119 foot elevations to ensure that flood protection measures were in accordance with design specifications. Specific plant attributes that were checked included structural integrity, sealing of penetrations, and operability of sump systems.

b. Findings

No findings were identified.

1R07 Heat Sink Performance

Triennial Review of Heat Sink Performance

a. Inspection Scope

The inspectors reviewed operability determinations, completed surveillances, vendor manual information, associated calculations, performance test results and cooler inspection results associated with the decay heat closed cycle heat exchanger (DCHE)-1B, the decay heat removal heat exchanger (DHHE)-1A and the service water heat exchanger (SWHE)-1C. These heat exchangers were chosen based on their risk significance in the licensees probabilistic safety analysis, their important safety related mitigating system support functions and their relatively low margin.

The inspectors determined whether testing, inspection, maintenance, and monitoring of biotic fouling and macrofouling programs for DCHE-1B and SWHE-1C were adequate to ensure proper heat transfer. This was accomplished by determining whether the test method used was consistent with accepted industry practices, or equivalent, the test conditions were consistent with the selected methodology, the test acceptance criteria were consistent with the design basis values, and reviewing results of heat exchanger performance testing. The inspectors also determined whether the test results appropriately considered differences between testing conditions and design conditions, the frequency of testing based on trending of test results was sufficient to detect degradation prior to loss of heat removal capabilities below design basis values and test results considered test instrument inaccuracies and differences.

The inspectors reviewed the methods and results of heat exchanger performance inspections for DCHE-1B and SWHE-1C. The inspectors determined whether the methods used to inspect and clean heat exchangers were consistent with as found conditions identified and expected degradation trends and industry standards, the licensees inspection and cleaning activities had established acceptance criteria consistent with industry standards, and the as-found results were recorded, evaluated, and appropriately dispositioned such that the as left condition was acceptable.

In addition, the inspectors determined whether the condition and operation of DHHE-1A and DCHE-1B were consistent with design assumptions in heat transfer calculations and as described in the FSAR. This included determining whether the number of plugged tubes was within pre established limits based on capacity and heat transfer assumptions. The inspectors determined whether the licensee evaluated the potential for water hammer and established adequate controls and operational limits to prevent heat exchanger degradation due to excessive flow induced vibration during operation. In addition, eddy current test reports and visual inspection records were reviewed to determine the structural integrity of the heat exchangers.

The inspectors determined whether the performance of the ultimate heat sink (UHS)and its subcomponents such as piping, intake screens, pumps and valves were appropriately evaluated by tests or other equivalent methods to ensure availability and accessibility to the in-plant cooling water systems.

The inspectors reviewed the licensees operation of the service water system (SWS)and UHS. This included a review of licensees procedures for a loss of the SWS or UHS and the verification that instrumentation, which is relied upon for decision making, was available and functional. In addition, the inspectors determined whether macrofouling was adequately monitored, trended, and controlled by the licensee to prevent clogging. The inspectors determined whether the licensees biocide treatments for biotic control were adequately conducted and whether the results were adequately monitored, trended, and evaluated. The inspectors also reviewed design changes to the SWS and UHS.

The inspectors performed a system walkdown of the service water and closed cooling water systems, which included the DCHE, DHHE, and SWHE heat exchangers, to determine whether the licensees assessment on structural integrity was adequate.

In addition, the inspectors reviewed the licensees available testing and inspection results, licensee's disposition of any active thru wall pipe leaks, and the history of thru wall pipe leakage to identify any adverse trends since the last NRC inspection. For closed cooling water systems, the inspectors reviewed operating logs or interviewed operators or the system engineer, to identify adverse make up trends that could be indicative of excessive leakage out of the closed system. For buried or inaccessible piping, the inspectors reviewed the licensee's pipe testing, inspection, or monitoring program to determine whether structural integrity was ensured and that any leakage or degradation was appropriately identified and dispositioned by the licensee.

The inspectors performed a system walkdown of the service water intake structure to determine whether the licensees assessment on structural integrity and component functionality was adequate and that the licensee ensured proper functioning of traveling screens and strainers, and structural integrity of component mounts. In addition, the inspectors determined whether service water pump bay silt accumulation was monitored, trended, and maintained at an acceptable level by the licensee, and that water level instruments were functional and routinely monitored. The inspectors also determined whether the licensees ability to ensure functionality during adverse weather conditions was adequate.

In addition, the inspectors reviewed nuclear condition reports (NCRs) related to the heat exchangers and heat sink performance issues to determine whether the licensee had an appropriate threshold for identifying issues and to evaluate the effectiveness of the corrective actions. These inspection activities constituted three heat sink inspection samples as defined in IP 71111.07. The documents reviewed are listed in the attachment to this report.

b. Findings

No findings were identified.

1R11 Licensed Operator Requalification Program

a. Inspection Scope

The inspectors assessed the activities and actions taken by the licensee to assess its readiness to respond to an event similar to the Fukushima Daiichi nuclear plant fuel damage event. This included

(1) an assessment of the licensees capability to mitigate conditions that may result from beyond design basis events, with a particular emphasis on strategies related to the spent fuel pool, as required by NRC Security Order Section B.5.b issued February 25, 2002, as committed to in severe accident management guidelines, and as required by 10 CFR 50.54(hh);
(2) an assessment of the licensees capability to mitigate station blackout (SBO) conditions, as required by 10 CFR 50.63 and station design bases;
(3) an assessment of the licensees capability to mitigate internal and external flooding events, as required by station design bases; and
(4) an assessment of the thoroughness of the walkdowns and inspections of important equipment needed to mitigate fire and flood events, which were performed by the licensee to identify any potential loss of function of this equipment during seismic events possible for the site.

b. Findings

Inspection Report 05000302/2011010 (ML111330166) documented detailed results of this inspection activity. Following issuance of the report, the inspectors conducted detailed follow-up on selected issues. One finding, a licensee identified violation (LIV), was identified during this follow-up inspection. The LIV is documented in section 4OA7 of this report.

.4 (Closed) NRC Temporary Instruction 2515/184, Availability and Readiness Inspection

of Severe Accident Management Guidelines (SAMGs)

On May 27, 2011, the inspectors completed a review of the licensees severe accident management guidelines (SAMGs), implemented as a voluntary industry initiative in the 1990s, to determine:

(1) whether the SAMGs were available and updated;
(2) whether the licensee had procedures and processes in place to control and update its SAMGs;
(3) the nature and extent of the licensees training of personnel on the use of SAMGs; and
(4) licensee personnels familiarity with SAMG implementation.

The results of this review were provided to the NRC task force chartered by the Executive Director for Operations to conduct a near-term evaluation of the need for agency actions following the Fukushima Daiichi fuel damage event in Japan. Plant-specific results for Crystal River Unit 3 were provided as an Enclosure to a memorandum to the Chief, Reactor Inspection Branch, Division of Inspection and Regional Support, dated June 02, 2011 (ML111530328).

4OA6 Meetings, Including Exit

Exit Meeting Summary

On July 06, 2011, the resident inspectors presented the inspection results to Mr. J. Franke, Site Vice President, and other members of licensee management. The inspectors confirmed that proprietary information was not provided or examined during the inspection.

4OA7 Licensee Identified Violations

The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of the NRC Enforcement Policy, for being dispositioned as a Non-Cited Violation.

10 CFR 50 Appendix B, Criterion III, Design Control, requires, in part, that measures shall be established to assure that applicable regulatory requirements and design basis for those structures, systems, and components are correctly translated into specifications, drawings, procedures and instructions. Licensee corporate engineering procedures EGR-NGGC-0005, Engineering Change; and Administrative Corporate procedure ADM-NGGC-0116, Nuclear Planning, implement those requirements. Contrary to the above, the licensee failed to translate the design basis requirements of modifications MAR 86-09-15, Raw Water Joint Encapsulation Sleeve, and MAR 90-08-16, Circulating Water Joint Encapsulation Sleeve, into work orders or procedures to ensure continued maintenance of design basis requirements. As a result, the raw water and circulating water encapsulation sleeves were found to have a larger gap than allowed by design, and consequently would have caused a greater internal flood rate into the auxiliary building had the expansion joints failed.

The performance deficiency of failing to maintain the gaps within the required tolerances on the raw water and circulating water encapsulation sleeves is more than minor because, if left uncorrected, would have the potential to lead to a more significant safety concern during a rupture of a raw water or circulating water expansion joint. The licensees corrective actions include revising maintenance procedures to add acceptance criteria for the encapsulation sleeve gaps. The finding was determined to be of very low safety significance (Green) because after performing additional engineering evaluations and calculations, it was concluded that the auxiliary building internal design basis flood requirements were not exceeded.

This issue was documented in the licensees corrective action program as NCRs 456729, 457510, and 457181.
