TOKYO (AP) — Japan's government vowed Tuesday to overhaul nuclear safety standards once its radiation-leaking reactor complex is under control, admitting its safeguards were insufficient to protect the plant against the March 11 tsunami.The struggle to contain radiation at the complex has unfolded with near-constant missteps — including two workers drenched Tuesday with radioactive water despite wearing supposedly waterproof suits. The unfolding drama has drawn increasing criticism of the utility that owns the plant as well as scrutiny of Japan's preparedness for nuclear crises.More than 11,000 bodies have been recovered, but officials say the final death toll is expected to exceed 18,000. Hundreds of thousands of people remain homeless, their homes and livelihoods destroyed.
