◼ For further expansion of fuel debris retrieval in scale, consideration will
be given to the methods including those for containing, transferring, andstoring of fuel debris, by assessing fuel debris retrieval in Unit 2, internal

SignificanceThis is the first attempt at fuel debris retrieval at the Fukushima Daiichi NPS.
• Expanding the containment barriers to the outside of the PCV is a basic on-site configuration for planned
retrieval operations.
• Future decommissioning efforts will make use of this experience and information from the retrieved
samples.

Issues and technical strategies
The issue is to carry out a series of operations step by step
amid uncertainties about the internal condition of the PCV.
Ensure that required performance is met✓ Functional verification in various conditions in mock-up tests.

Careful planning✓ Proceed safely and carefully, keeping in mind the experienceof defects during operation.

Further expansionof fuel debris retrieval in Unit 3 (1)SignificanceFurther expansion of fuel debris
retrieval in scale is an important
process in decommissioning, andits reliable implementation will
determine the success or failureof the decommissioning project.
Issue

The selection of the retrieval
method is an extremely
important decision.
• Before the selection, not only TEPCO but
the government and NDF should
cooperate in a comprehensive review
and evaluation.**The Sub-Committee for the Evaluation of Fuel Debris Retrieval
Methods, established in February 2023, has started theexamination and evaluation.

Factors that make fuel debris retrieval difficult

After fully recognizing the factorsthat make fuel debris retrieval
difficult and appropriate retrieval
methods should be examined.

① Extremely high radiation dose in PCVs
and RPVs② High-radiation dose in reactor buildings③ Lack of on-site information④ Building containment barriers⑤ Criticality control⑥ Waste management8

Characterization

Accumulate trial results and verify theirvalidity to establish a development flow of themedium-to-long-term analysis plan with ananalysis project approach using statisticalmethods

For a variety of solid waste, it is needed todevelop a medium-to-long-term analysis
strategy that defines its priority, theobjective of the analysis, and quantitative
targets, etc., and to proceed withanalysis/evaluation accordingly.

Storage/management
Storage/management of solid waste
according to the progress of
decommissioning work in the future should
be advanced in a safe and reasonable
manner

Processing/disposal
The Mid-and-Long-term Roadmap statedthat the specifications of waste form andtheir production methods will be determinedin Phase 3, the study on appropriate overallmeasures should be initiated for specificmanagement for solid waste.

Transit from classification based on thesurface dose rate to manage based onradioactivity concentration and examine
rational waste classification and on-site reusein preparation for the expected increase ofsolid waste generation.
Create processing/disposal options for solid
waste by examining pending issues related toprocessing technology and disposal options.
Compare and evaluate options using thecharacteristic data that are becoming clear, andexamine to establish a waste stream that issuitable for the feature of solid waste.

treated water management

Major Targets◼ To suppress the amount of contaminated water generated to 100 m3/day
or less within 2025 and to approximately 50 to 70 m3/day around theend of FY2028.
◼ To discharge ALPS-treated water safely and reliably in order to secure
the site and other resources and to facilitate the entire
decommissioning process.

Issues and technical strategies

Contaminated water management
Contaminated water generation is
expected to be reduced to 100
m3/day or less, and the issue is to
reduce it further.

Proceed with local watertight work in thebuilding, in addition to the ongoing loweringof the water level of sub-drains and work on
facings.

In addition to selecting methods fordebris retrieval in progress, it is also
necessary to consider measuresover the medium to long term.

Since each fuel debris retrieval method
requires different purification systems andwatertight measures for buildings, establish
contaminated water management measuresaccording to the method, consideringinterference with retrieval operation.

Treated water management

After confirming that the concentration of radionuclides other than tritium in
ALPS-treated water before dilution is definitely below the regulatory limit*, diluteand discharge the ALPS-treated water.
✓ Conducted by TEPCO and third-party organizations with expertise inanalyzing radioactive materials.
*The sum of the ratios against the regulatory concentrations limits is less than 1.

Several organizations provide marine monitoring, including TEPCO, theMinistry of the Environment, the Nuclear Regulation Authority, and Fukushima

４．廃炉の推進に向けた分析戦略
Significance of analysis for decommissioning

SignificanceAnalysis with a diverse variety of analysis targets, objectives, and radiationdose rates is essential to the decommissioning the Fukushima Daiichi NPS.
• If the range of uncertainty about fuel debris is reduced, there will be no need to include excessive
margins, improving the promptness and rationality of decommissioning.

• Analysis to obtain property data is essential in examining processing/disposal methods of solid waste.

4. Analysis strategy for promoting decommissioning

Issues and strategies related to analysis for decommissioning
Issues and strategies
Strengthening analysis methods and structures
To prevent decommissioning workfrom stagnating, the issue is toanalyze according to the plan,considering the future expansion of
the demand for analysis.

It is necessary to have a high levelof ability to develop analysis plansthat anticipate in advance how theanalysis results are utilized. (This is
not feasible for a single individual.)

Identify types of waste with a high priority for
analysis and consider policies for characterization
and analysis plans based on the characteristics ofeach type.
Integrate and coordinate these analysis plans,
formulate the annual development of the analysis
capabilities, and incorporate them into personnelplans.
Organize an Analysis Coordinating Committee andan Analysis Support Team to confirm analysis
plans and provide advice on problem-solving.

Diversification of analytical techniques to increase sample size and volume
Although sample analysis canmeasure many analysis items, theissue is that each analysis takes along time, and the amount analyzed
each time is small.

Compared with sample analysis, it is important tostudy the application method of non-destructive
measurement, which can measure large amounts
in a short time.
