2. Concept for reducing risks
and securing safety for decommissioning of the Fukushima Daiichi NPS

安全確保の考え方
Approach to ensuringsafety during decommissioning◼ As for decommissioning of the Fukushima Daiichi NPS containing the reactors
involved in the accident, its peculiarities regarding safety should be fullyrecognized to ensure safety and sufficient attention should be paid to “the safety
perspective” and “the operator’s perspective”.
✓ Safety perspective : Ensuring safety should be the starting point for consideration.
Determining the most appropriate safety measure (ALARP※)✓ Operator’s perspective : Perspectives and judgements from the standpoint of those
who are familiar with the site and perform operations on site

Peculiarities of Fukushima Daiichi NPS
✓
✓
✓
✓
✓

A large amount of radioactive material is in an unsealed state, and in unusual and various(atypical) forms
Barriers for containing radioactive materials are incomplete
Significant uncertainties exist on the state of radioactive materials and containment barriers
Difficulty in accessing the site and installing instrumentation devices to obtain on-site
information
Since the current level of radiation is high and further degradation of containment barriers is
a concern, it is necessary to take measures in consideration of the time axis without
prolonging the decommissioning activities※ Abbreviation of As Low As Reasonably Practicable. This is the principle that the radiological impact must be
as low as reasonably achievable.

and progress for fuel debris retrieval
Major targets◼

Trial retrieval in Unit 2 was scheduled to begin within 2021, but the process will be reviewed to
improve work safety and reliability during retrieval in light of the impact of the COVID-19
pandemic, the mock-up testing that has been conducted since February 2022, and the current
on-site situation. The work is expected to start in late FY2023.

◼

For further expansion of fuel debris retrieval in scale, consideration will be given to themethods including those for containing, transferring, and storing of fuel debris, by assessing
fuel debris retrieval in Unit 2, internal investigations, research and development, and the onsite environmental improvement, etc.

and technical strategies for trial retrieval from Unit 2
燃料デブリ取り出しに係る主な目標と進捗(internal investigation and fuel debris sampling)

Challenges and technical strategies◼ Trial retrieval (internal investigation and fuel debris
sampling) is a series of operations, and fuel debris
sampling is one part of 11 steps.
◼ After opening the hatch of the penetration X-6 andextending the containment barrier outside the PCV,
it is important to ensure containment as the inside ofthe enclosure becomes progressively contaminated.
◼ For on-site applications with uncertainty, thechallenges are to ensure functionality verification
under various conditions and equipment can be
rescued in case of emergency.

✓ It is necessary to ensure that the required conditions
are satisfied by conducting mock-up tests.
✓ Due to the uncertainty of the PCV internal situation,
work must be performed safely and carefully,
keeping in mind that things may not go as planned.

Challenges and technical strategies◼

A variety of retrieval methods have been studied
since FY2021, not ruling out any possibilities.

◼

The partial submersion method*1 and submersion
method*2 that are being discussed pose thefollowing challenges: feasibility of on-site
construction under high radiation dose, significant
increase in the amount of construction materials
and waste, and measures to be taken when fueldebris is retrieved.

✓ Once feasibility has been confirmed tosome extent, it will be necessary tonarrow down the options step by step
while proceeding with the design.
✓ Other retrieval methods should bestudied as needed.

Major targets◼

The Solid Waste Management Plan (hereinafter referred to as the “Storage Management Plan”) is appropriately
developed, revised and implemented, with updating the estimated amount of solid waste to be generated in the next ten
years periodically. According to this Plan, temporary outdoor storage of the solid waste will be eliminated completely by
FY 2028 (except for secondary waste generated by water treatment and targets of reuse/recycling).

◼

Given the prospects of processing/disposal methods and technology related to their safety presented in FY 2021,
appropriate measures should be studied as management approaches for overall solid waste to establish a waste stream*according to the properties of solid waste.
*A series of handling procedures for each type of waste, from generation/storage to processing/disposal.

and technical strategies for waste management
Challenges and technical strategies
Characterization◼ For a variety of solid waste, it is needed todevelop a medium-to-long-term analysis
strategy that defines its priority, the objective of
the analysis, and quantitative targets, etc., andto proceed with analysis/evaluation accordingly.

✓ Accumulate trial results and verify theirvalidity in order to establish a development
flow of the medium-to-long-term analysis
plan with an analysis project approach
using statistical methods,.

Storage/management◼ Storage/management of solid waste according
to the progress of decommissioning work in the
future should be advanced in a safe andreasonable manner, including temporary
outdoor storage of the solid waste (except forsecondary waste generated by water treatment
and targets of reuse/recycling) will beeliminated (by FY 2028), that is stated in the
Mid-and-Long-term Roadmap.

✓ Examine further possibilities by referring toadvanced cases of overseas, while steadily
continuing approach for volume reduction.

Processing/disposal✓ Create processing/disposal options for solid
waste by examining pending issues related toprocessing technology and disposal options.

◼ The Mid-and-Long-term Roadmap stated thatthe specifications of waste form and theirproduction methods will be determined inPhase 3, the study on appropriate overallmeasures should be initiated for specificmanagement for solid waste.

✓ Promote volume reduction through incineration,and cutting/crushing, and steadily consolidatestorage inside buildings.

✓ Compare and evaluate options using the property
data that are becoming clear, and examine toestablish a waste stream that is suitable for thecharacteristics of solid waste.

汚染水対策に係る主な目標と進捗
汚染水対策に係る主な目標と現状

Major targets and technical strategies for contaminated water management

Major targets◼ To arrange the relationship with a decommissioning process including full-scale
fuel debris retrieval beginning in the near future, and to promote examination of
the measures of the contaminated water management for medium-and-longterm prospects.

Challenges and technical strategies◼ The water quality of contaminated water depends on the cutting and fabrication
method (forms of α-nuclides)◼ It is difficult to assume the water quality in a situation where the fuel debris
retrieval method has not been determined. The water treatment systems shouldhave a system configuration to cope with a wide range of water quality.

✓ It is necessary to determine the required specifications for the water treatment
systems when retrieving fuel debris, then incorporate into basic design
promptly in order to review the overall picture in considering the share offunctions with the existing systems and to promote planned replacement of
the existing systems.

Major targets and technical strategies for discharging ALPS-treated water into the ocean

Major targets◼ For the ALPS-treated water currently stored in tanks, measures will betaken for discharging the treated water about two years after the Basic
policy (released in April 2021)

Challenges and technical strategies◼ In addition to “reliably” operate a series of plans including system
operation, analysis of ALPS-treated water, maintenance and response
measures in the event of trouble, TEPCO must review and expand theplans as needed and ensure its transparency.

✓ It is necessary to reassess radiation impacts on human andenvironment based on the nuclides to be analyzed, and disseminate
the assessment results with high transparency.

4. Analysis strategy for promoting decommissioning

４．廃炉の推進に向けた分析戦略
Significance and technical strategies of analysis

Significance and current state◼

At present, due to the large range of uncertainty regarding fuel debris properties, safetymeasures should be studied conservatively.

◼

If the range of such uncertainty can be reduced, there is no excessive margins needed, andthus, rational safety measures can be studied, it enables the promptness and rationality ofdecommissioning to improve.

Challenges and technical strategies◼

Since the fine fuel debris generated as
retrieval of fuel debris progresses arediverse with high radiation dose, it is achallenge to establish an efficient system
for analysis.

✓ It is effective to expand the analysis data
under the appropriate division of roles among
the facilities in the Ibaraki area, where facilities
and equipment are enhanced, and the new
analysis facilities.
✓ It is important to efficiently promote humanresource development with the cooperation ofother institutions.

4. Analysis strategy for promoting decommissioning

Improvement of the quality of sample analysis results
and use of non-destructive assay

Challenges and technical strategies✓ For non-destructive assay, time measured isshorter than that of sample analysis, and a larger
quantity can be measured per measurement.
✓ In order to improve the accuracy of fuel debris
characterization, application methods of nondestructive assay should be studied in theprocess from retrieval to storage.

◼ Sample analysis can perform many
analysis items, but the time required islong and the amount analyzed is small.
So, it is difficult to measure a larger
quantity analyzed.
