| contents | Nuclear power plants are not only vital sources of clean energy but also powerful facilities for probing new physics beyond the Standard Model. Due to the intense gamma-ray flux and an appropriate energy conditions, they are particularly well-suited for searches of light hypothetical particles such as sub-MeV axions and axion-like particles (ALPs). In this work, we propose to search for the ALPs in the REactor Neutrino COherent scattering Detection Experiment (RECODE), where two low-threshold, high-purity germanium detectors are placed at 11 m (near point) and 22 m (far point) from a 3.4 GW nuclear reactor at Sanmen nuclear power plant. With a 10 kg$\cdot$year exposure, we demonstrate that the expected sensitivities to the ALP couplings to the electrons and photons are competitive with or surpass the available results from the beam-dump experiments. A planned upgrade to 100 kg$\cdot$year will fully cover the so-called {$\it$ cosmological triangle} region, probing unexplored parameter space relevant to axions. |
