Abstract

Rector neutrinos have been a tool to investigate neutrino properties for more than 60 years. The reactor neutrino flux was measured throughout 80s-90s. In the 2000s, reactor neutrino oscillations at large baselines were observed by the KamLAND experiment and later in 2012 at short baselines by the Daya Bay, Double Chooz and RENO experiments. Reactor neutrino experiments have significantly contributed to our current knowledge of oscillation parameters. The detector technology has been majorly improved over decades and we have entered era of precise measurements. The recent absolute measurement reactor neutrino flux and spectral shape revealed deviations from the prediction model, known as reactor antineutrino flux and spectrum shape anomalies. In this article, we review the latest development in short baseline reactor experiments and we discuss observed anomalies.
