NRA receives the Hamaoka 3 and 4 application withdrawals
The NRA received withdrawal documents for both units' installation-change applications and for Unit 4's construction-plan and operational-safety-rule applications.
AFFECTED
Hamaoka 3 · Hamaoka 4 · Chubu Electric
NEXT OBSERVABLE GATE
A new operator decision and new conformity applications would be required before an active regulatory restart pathway can resume.
BUSINESS IMPLICATION
The active review path has ended for both units, increasing restart uncertainty while leaving the units in the 33-reactor existing-fleet denominator.

NRA / N-ADRES source ↗REACTOR REVIEWNRA schedules a non-public safety-facility review for Kashiwazaki-Kariwa 6 and 7
The NRA scheduled a conformity-review meeting covering specific severe-accident response facilities for Units 6 and 7. The meeting is non-public because it concerns protected facility information.

NRA schedules a non-public safety-facility review for Kashiwazaki-Kariwa 6 and 7
The NRA scheduled a conformity-review meeting covering specific severe-accident response facilities for Units 6 and 7. The meeting is non-public because it concerns protected facility information.
AFFECTED
Kashiwazaki-Kariwa 6 · Kashiwazaki-Kariwa 7 · TEPCO
NEXT OBSERVABLE GATE
Any resulting requests, submissions or regulatory conclusions published after the closed review.
BUSINESS IMPLICATION
The review is relevant to completion risk and sequencing for TEPCO’s restart programme, but the meeting notice alone does not indicate approval or delay.

The meeting considered TEPCO responses and technical material covering ageing mechanisms, instrumentation, concrete and steel structures, and seismic and tsunami safety.
AFFECTED
Kashiwazaki-Kariwa 6 · TEPCO
NEXT OBSERVABLE GATE
NRA resolution of outstanding review comments and a decision on the long-term facility management plan.
BUSINESS IMPLICATION
The outcome affects the unit’s long-term operating permissions and may drive inspection, replacement and engineering-service requirements.

Sendai dry-storage proposal advances through technical review
Kyushu Electric presented responses and supplementary conformity material for proposed spent-fuel dry-storage facilities at Sendai.
AFFECTED
Sendai 1 · Sendai 2 · Kyushu Electric
NEXT OBSERVABLE GATE
NRA confirmation that the design and supporting analysis satisfy the installation-permission requirements.
BUSINESS IMPLICATION
Additional storage capacity can reduce a future fuel-management constraint and creates potential demand across casks, civil works, handling systems and inspection services.

AFFECTED
National fleet
NEXT OBSERVABLE GATE
Monitor reactor-specific hearings and document revisions rather than treating the periodic snapshot as a restart schedule.
BUSINESS IMPLICATION
The document is the common regulatory baseline for comparing review maturity, unresolved technical topics and likely demand for safety-related work.
