1.0 INTRODUCTION

In accordance with the requirements of Technical Specification 3.4.2, an annual written report shall be submitted prior to March 1 of each year.

This report is arranged into two sections. Section 2.0 provides a discussion of the nine items required by the Technical Specifications. Section 3.0 provides a discussion of optional issues.

.2.0 ITEMS REQUIRED BY TECHNICAL SPECIFICATION 3.4.1 The report shall include the following:

a. The status of the facility;

b. The results of the radiation surveys and monitoring station dosimeter readings;

c. The results of environmental sample analysis surveys;

d. The results of quarterly intrusion alarm system checks;

e. The amount of radioactive materials removed from the N.S. Savannah (NSS) by releases, discharges, and shipments of radioactive waste material;

f. A description of the principal maintenance performed on the vessel;

g. Any unauthorized entry into radiation control areas by visitors or employees and corrective action taken to improve access control;

h. Any degradation of one of the several boundaries which contain the radioactive materials aboard the NSS;

i. Results of occupational exposure indicated by personal dosimetry.

2.1 STATUS OF THE FACILITY During 2008, the NSS has remained "Mothballed" per the requirements of Regulatory Guide (RG) 1.86, "Termination of Operating Licenses for Nuclear Reactors," Reference (a). This state of protective storage was approved in Reference (b). This RG describes the now outmoded Mothballing option of protective storage.

During calendar year (CY) 2008, the ship was berthed in two locations:

" BAE Systems Norfolk Ship Repair facility in South Norfolk, VA (January I-May 7).

" Pier 13, Canton Marine Terminal, 4601 Newgate Ave., Baltimore, MD (May 8 - December 31).

Keystone Shipping Company, acting as General Agent for MARAD, awarded BAE Systems Norfolk Ship Repair a contract to perform drydocking and exterior topside maintenance, repairs and painting in August 2007. Work commenced on portions of the topside (i.e., areas above the waterline) in late CY 2007. The NSS was placed onto the Titan drydock on January 19, 2008, and remained there until March 3. While on the drydock, BAE water-jetted, prepared and coated the entire exterior envelope of the ship. MARAD paid particular attention to inspecting and verifying the integrity of the underwater hull repairs made during the 1994 drydocking availability. Hull inspections identified no new degradation. Additional detail regarding the scope of the BAE contract award, and other principal maintenance performed during CY 2008 is listed in section 2.6.

The NSS was temporarily layberthed at the shipyard after completion of the BAE contract work, pending the award of long-term layberthing contract. Keystone solicited bids for the layberthing contract in February - March 2008. Four bids were received from facilities in Norfolk, VA; Philadelphia, PA and Revision 0 5

Savannah Technical Staff License NS-I Annual Report 2008, Revision 0 February 27, 2009 Baltimore, MD. Keystone selected the bid submitted by Vane Bros. Inc., dba Canton Marine Terminals, as the best value, and awarded the contract in April 2008. The NSS was towed from the BAE facility on May 7, and arrived at the layberth location on May 8, 2008. The base year contract continues through May 7, 2009.

Similar to 2007, MARAD and contractor personnel were routinely on board the NSS during normal workdays throughout 2008. This regular attendance had the beneficial effect of improving the ship's physical condition and staff proficiency with the conduct of licensed activities.

2.1.1 LICENSE ACTIVITIES MARAD completed two significant licensing actions in 2008.

" License Amendment 14 was approved on April 3, 2008. It redefines Radiological Controlled Areas (RCA), requires visitors to be escorted and resolves conflicts that result from implementation of the Decommissioning Quality Assurance Plan.

" Post Shutdown Decommissioning Activities Report (PSDAR), Rev. 1, Reference (c), was submitted on December 11, 2008.

MARAD continued developing and implementing a prioritized procedure and process development program in accordance with its overall license management program.

An announced facility inspection was conducted by the USNRC assigned Region I inspector on September 10, 2008.

2.1.2 ORGANIZATION In 2008 MARAD made no substantial changes to the organization. The individuals filling the positions of Marine Surveyor and Facility Site Manager have left the Savannah Technical Staff. MARAD plans to combine these positions at a future date, pending availability of resources to do so.

2.1.3 REVIEW OF OTHER TECHNICAL SPECIFICATIONS REQUIREMENTS In accordance with the NSS Technical Specification 3.6.3, the Safety Review Committee (SRC) is specifically required to review the following items with or without a formal meeting:

a. Proposedchanges to Technical Specifications.

License Amendment Requests (LARs) and Responses to Requests for Additional Information on LARs were reviewed and approved prior to submittal.

b. Evaluations requiredby 10 CFR 50.59.

No Changes, Tests or Experiments were proposed in 2008 that would require a 50.59 evaluation. Note that this sentence also meets the reportingrequirement of 10 CFR 50.59(d)(2) to provide a brief descriptionof any changes, tests, and experiments, including a summary of the evaluationof each.

c. Proposedchanges or modifications to a RadiologicalControlledArea enty alarm system or reactor containment vessel system.

There were no changes to a RCA entry alarm system or to a reactor containment vessel system.

d. Evaluations ofsubstantive changes to the results of radiologicalsurveys.

There were no substantive changes to radiation surveys or security surveillance procedures.

e. Proceduresand revisionsper Technical Specification 3.5.

Procedures listed in TS 3.5 were reviewed prior to approval.

f. Evaluations of reportedviolations of Technical Specifications.

There were no TS violations during the reporting period.

g. Evaluations of reportableevents per Technical Specification 3.4.3.1.

There were no reportable events during the reporting period.

h. Evaluations of deviations allowed by Technical Specification 3.7.1.7.

All deviations were reviewed prior to implementation. The following limited duration deviations were used as needed in the reporting period:

" Alarm Systems - Testing, Maintenance (Troubleshooting / Repair) and Modification.

• Loss of Electrical Power - invoked during brief periods of power disconnects while the NSS was at BAE Systems prior to, during and following the dry-dock contract.

i. Audits and self assessments to verify the effectiveness of the Decommissioning Quality Assurance Plan.

Self assessments were performed in the following functional areas in the reporting period:

• Comprehensive Action Tracking System;

" Security;

" Access Control;

• NSS Records Storage Area at US Merchant Marine Academy, Kings Point, NY;

• Implementation of 2007 Records Assessment Recommendations.

j. Annual reports to the NRC.

The CY 2007 Annual Report was reviewed prior to its submittal on February 28, 2008.

2.1.4 DECOMMISSIONING PLANNING ACTIVITIES Decommissioning planning during the reporting period focused on facility and administrative activities necessary to bring the Savannah into conformance with SAFSTOR requirements. The underlying intent is described more fully in reference (c). The following significant activities were completed in CY 2008:

The Engineering, Management and Oversight Services (EMOS) contractor, Areva Federal Services, LLC, completed a "SAFSTOR Plan" (STS-104). This plan defines the activities necessary to implement the protective storage requirements of SAFSTOR, which are more comprehensive and programmatic than the mothballing requirements of Reference (a) that were implemented in 1975. The SAFSTOR Plan was reviewed and approved by the STS organization, including the SRC and the Executive Steering Committee. Upon adoption, the SAFSTOR Plan became the basis for subsequent decommissioning planning activities.

Additional plans and reports stemming from the SAFSTOR Plan included:

• SAFSTOR Cost Estimate, Schedule and Work Breakdown Schedule

" Historic Site Assessment Report (STS-109)

• Characterization Survey Plan (STS-I 10)

• Electrical Upgrade Plan (STS-I 13)

• HVAC Upgrade Plan (STS-1 14)

• Mechanical Upgrade Plan (STS-I 15)

• Safety Upgrades Plan (STS-1 16)

" The Maritime Administration published its Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) for the decommissioning of the N.S. Savannah in May 2008.

These were submitted to the NRC for information on October 3, 2008 [Reference (d)].

Revision 0 7

Savannah Technical Staff License NS-1 Annual Report 2008, Revision 0 February 27, 2009 As noted in section 2.1.1, the revised PSDAR was prepared, approved and submitted to the NRC. The PSDAR combines elements of the SAFSTOR planning activities, and the MARAD EA and FONSI, together with updated decommissioning funding estimates prepared during the 4Q of CY 2008.

2.1.5 SAVANNAH EMERGENCY RADIOLOGICAL ASSISTANCE TEAM (SERAT)

Composition of the SERAT was reassigned to the ship's retention crew and designated members of the Savannah Technical Staff effective upon the departure of the NSS from the Newport News - Hampton Roads area. All local responders were trained following the ship movement. All SERAT members are located within a 2-hour response radius of the ship's current location.

2.2 RADIATION SURVEYS AND MONITORING STATION DOSIMETER READINGS Routine radiological surveys were conducted in accordance with the established program. Radiological survey measurements were taken in all RCAs and various non-RCAs. All non-RCA radiation survey results were insignificant as compared to background radiation levels.

Fixed point radiation surveys are performed during TLD change outs. Results from the TLDs from all monitoring stations indicated that readings were insignificant as compared to the background radiation levels. No fixed point radiation dose rate exceeded 5 pR/hr (micro-R/hr).

2.3 ENVIRONMENTAL SAMPLE ANALYSIS SURVEYS Environmental water and sediment samples were taken adjacent to the ship at various times during the calendar year as required by TS and ship's movement. Sediment samples were taken at the intended layberth location at Pier 13, Canton Marine Terminal, Baltimore, Maryland prior to the ship's arrival.

Those samples indicated the presence of low level concentrations of Cs-137. The levels of Cs-137 at 1.03E-0 I pCi/g and 1.21 E-0 I pCi/g are consistent with Cs- 137 concentrations typically found in the environment. NSS sediment samples taken in October 2008 were below detectable levels. To establish local environmental radiological concentrations in and around the Pier 13 site, additional background sampling may be performed.

The environmental sample results indicate that the radiological conditions in the environment surrounding NSS are insignificant as compared to expected background conditions. Therefore, based on the results of the radiological environmental monitoring program, NSS operations did not have any adverse effects on the health and safety of the public or on the environment in 2008.

Savannah Technical Staff License NS-1 Annual Report 2008, Revision 0 February 27, 2009 2008 RADIOLOGICAL ENVIRONMENTAL SAMPLING RESULTS - Data notes from lab reports (A) Sediment samples are reported on a dry weight basis and are decay corrected to the Sample Collect date (B) Calculated MDA as an a-posteriori values at the 95% Confidence Level (C) Water was decanted off of sediment samples 2.4 QUARTERL Y INTRUSION ALARM SYSTEM CHECKS Routine security surveillances were conducted as required and the Key and Seal log was reviewed on a quarterly basis. No deficiencies were noted.

Alarms were tested monthly and as needed following security system maintenance and modifications.

2.5 RADIOACTIVE MATERIALS REMOVED BY RELEASES, DISCHARGES AND WASTE SHIPMENTS No radioactive materials were removed from the ship as described below:

2.5.1 RELEASES There were no releases.

2.5.2 DISCHARGES There were no discharges.

2.5.3 SHIPMENTS There were no shipments.

2.6 PRINCIPAL MAINTENANCE PERFORMED The major maintenance activity of CY 2008 was the drydocking and topside maintenance shipyard availability completed at BAE Systems Norfolk Ship Repair. In addition to the routine need to inspect and fepair the ship's underwater hull, MARAD used this maintenance availability to perform a comprehensive assessment of the physical-condition of the ship's primary structure and exterior envelope.

As part of the assessment, MARAD entered into an agreement with the American Bureau of Shipping (ABS) to return the Savannah to hull classification. Once classed, the ABS will provide independent monitoring and review of the ship's structural condition.

At the previous drydocking availability in 1994, extensive repairs were made to the underwater hull by clad-welding deep pits; renewal of several hundred linear feet of welded butts and seams; and installation of steel doubler plates over four areas of generalized erosion and pitting at the "wind and water" interface.

These repairs were subjected to intense survey and inspection by ABS and STS during the 2008 drydocking. All of the repairs were found to be in satisfactory condition. Three of the doubler plates were removed, and several of the underlying locations were inserted with new steel plates. The fourth doubler plate is located adjacent to the Cold Chemistry Laboratory, and was thus not removed because of the need to dismantle the laboratory equipment (with requisite radiological controls) to provide access for the required hot work in that area.

No record of ballast tank or other innerbottom tank inspections was found for the 1994 or the preceding 1975 drydocking availabilities. Consequently, planning for the 2008 drydocking availability included inspection and survey of all innerbottom and ballast tanks. All tank surveys and inspections were Revision 0 12

Savannah Technical Staff License NS-1 Annual Report 2008, Revision 0 February 27, 2009 completed, except for the number 4 centerline ballast tank', and ballast and innerbottom tanks within the Reactor Compartment. Ultrasonic thickness gaugings were taken of the cargo hold tank tops (a principal structural member of the ship), and the ship's exterior hull structure. Additional gaugings were taken adjacent to each cargo hatch opening in the main deck; on the cargo hatch covers themselves, and at selected areas of structural concern and interest.

The entire exterior surface of the ship was prepared by waterjetting. The underwater hull, freeboard and main deck areas were prepared to bare steel, with all previous and original coating materials removed. A new high performance epoxy coating system was applied, with high gloss acrylic urethane topcoat. The underwater hull received one coat of conventional anti-fouling coating. Other areas of the topside exterior were prepared to a slightly lesser standard, with some original coating materials left intact. All previously existing hydraulic oils and similar materials were removed from non-functioning deck equipment, to minimize the risk of discharge of such materials into the environment.

The exterior envelope of the ship forms the perimeter boundary for licensed activities. Maintenance of the envelope ensures that the nuclear facilities housed inside the ship are protected. Based on the review of available records, it is surmised that the 2008 drydocking was the first comprehensive examination of the ship's structural fabric since 1967, when the ship underwent "Special Survey No. 1" for the ABS.

Major drydocking work completed:

• Underwater hull cleaning, surface preparation and coating;

• Inspection and repair of 1994 hull repairs;

• Freeboard preservation from deep loadline to top of the rails;

• Topside and superstructure preservation including weather exposed decks;

• Audio gauge exterior hull, decks, superstructure, tank tops and tanks;

• Cathodic protection system; service and repair;

• Removed ship's propeller and stored it on No. 7 cargo hold hatch cover;

• Permanently sealed and capped the stern tube opening after removal of the propeller;

• Examined, tested and repaired (as required) all hull blanks;

• Examined and repaired as required bilge keel and bilge strake rivets;

• Performed miscellaneous steel renewals, as needed, to side shell, bottom and main deck plating;

• Removed ceramic tiles and magnesite underlayment from the Promenade Deck to permit inspection, repair and coating of underlying steel decks;

• Internally inspected double bottom ballast tanks, forward and after peak tanks, No. 1 Deep Tank, and various voids and pipe tunnels;

• Replaced the weathertight seals on main deck hatch covers at cargo holds 1, 2, 3, 4 and 7.

In summary, the structural condition of the ship was found to be very good. In particular, the innerbottom structure was found to have little-to-no structural degradation, and the original tank coatings were found intact and serviceable. All major hull strength components were inspected, repaired if necessary, and coated for long-term preservation. The thorough inspections and surveys of the ship's structural condition were documented to provide a baseline for the balance of the protective storage period.

Maintenance activities continued once the ship was moved to its Baltimore layberth. From that point onward, the maintenance strategy focused on routine preventative maintenance, and restoration of ship systems and equipment necessary for husbanding the ship, and long-term retention. In addition, discrete The No. 4 centerline ballast tank is filled with water containing chemical compounds of indeterminate origin. The tank will be inspected at a future date after the water is processed and discharged. Structural ins'pections were completed of the exterior of the tank boundaries, however.

2.7 UNAUTHORIZED ENTRY INTO RADIA TION CONTROL AREAS AND CORRECTIVE ACTIONS TAKEN TO IMPROVE ACCESS CONTROL No unauthorized entries were made into any Radiation Control Area in the previous year.

2.7.1 EVENT DISCUSSION None 2.7.2 IMPROVEMENTS TO ACCESS CONTROL None 2.8 INSPECTION OF BOUNDARIES CONTAINING RADIOACTIVE MATERIALS The annual RCA boundary inspections required by Technical Specification 3.7.6 were conducted in December 2008.

There was no notable change in the condition of the primary and auxiliary systems since the last inspection series in December 2007. The exception is a more detailed inspection of the lower level Reactor Compartment port aft corner noted a small amount of standing water. A follow-up inspection in January 2009 noted significantly less water. This area will be monitored on a quarterly basis until the source of water is determined.

SUMMARY

OF 2008 OCCUPATIONAL EXPOSURE As a result of the N.S. Savannah being in the Mothballed state of protective storage, no individual is expected to receive in one year, from sources external to the body, a dose in excess of 10% of the limits specified in 10 CFR 20.1201. Thirty (30) individuals were monitored with TLD and self-reading dosimetry during their entries into radiological controlled areas. All personnel received zero dose from occupational sources during the monitoring period. Therefore, MARAD has no requirement under 10 CFR 20.1502, "Conditions requiring individual monitoring of external and internal occupational dose" to reasonably anticipate that there is a need to "monitor exposure to radiation and radioactive materials at levels sufficient to demonstrate compliance with the occupational of dose limits." Likewise, MARAD Revision 0 14

Savannah Technical Staff License NS-1 Annual Report 2008, Revision 0 February 27, 2009 has no requirement under 10 CFR 20.2106, "Records of individual monitoring results" to maintain records of doses when an individual is not required to be monitored.

3.0 OTHER REPORTS 3.1 10 CFR 50.59 BIENNIAL REPORT Historically, the Biennial Summary Report has been included in each Technical Specification Annual Report (see 2.3. L.b of this report). No 10 CFR 50.59 Evaluations were completed in 2008.

SUMMARY

OF TECHNICAL SPECIFICATIONDEVIATIONS No new Technical Specification Deviations were generated.

3.3 DECOMMISSIONINGFUNDING STA TUS The following is intended to meet the reporting requirement of 10 CFR 50.75(f)(1). The N.S. Savannah and its nuclear reactor are federally-owned facilities, represented by the United States Department of Transportation, acting by and through the Maritime Administration. As such, funding for the decommissioning and disposal of the NSS reactor and nuclear systems components and waste must be provided by appropriations from the United States Congress. MARAD maintains no funding reserve, nor does it accumulate or collect funds. As allowed by 10 CFR 50.75(e)(l)(iv), MARAD will obtain funds for decommissioning when necessary. Appropriated funds for FY 2008 were $4.7 million and were sufficient to support long-term layberthing following the drydocking. At the onset of FY 2009 (October 1, 2008), $3.0 million had been requested to continue NSS licensed activities and SAFSTOR preparations2. Once SAFSTOR preparations are completed, and until 2023, funding can be reduced to a level commensurate with maintaining the facility and license in a SAFSTOR condition.

3.4 10 CFR 50.54 WINSURANCE ANNUAL REPORT The regulations require each power reactor licensee to obtain insurance available at reasonable costs and on reasonable terms from private sources or to demonstrate to the satisfaction of the NRC that it possesses an equivalent amount of protection covering the licensee's obligation. As a federal agency, MARAD is self-insured.
