Abstract

Context

In recent years, Phaeocystis globosa has become a typical red tide species in the Beibu Gulf, posing a safety hazard to the cold-water intake system of the Guangxi Fangchenggang Nuclear Power Plant.

Aims

To establish an effective early risk-warning monitoring and ensure the safety of nuclear power plant cold-water intakes.

Methods

In this study, a multifactor and multilevel early risk-warning monitoring system was established using the early warning idea of ‘risk grading’.

Key results

The results showed that this method can analyse the influence trend of marine-environment changes on the growth of P. globosa and improve the timeliness of early warning and forecasting.

Conclusions

The method established in this paper can effectively guide coastal nuclear power enterprises to conduct early risk warning and monitoring of P. globosa and improve the accuracy of early warning and forecasting.

Implications

The methed is of great significance to coastal nuclear power enterprises dealing with red tide disasters caused by P. globosa blooms.

Keywords: accident life-cycle theory, cold-source safety, nuclear power plant, Phaeocystis globosa, risk grading, risk warning, risk warning and monitoring system, the early warning monitoring indices.
