  We present the detection of 51 thermonuclear X-ray bursts observed from 4U
1636-536 by the Neutron Star Interior Composition Explorer (NICER) over the
course of a three year monitoring campaign. We performed time resolved
spectroscopy for 40 of these bursts and showed the existence of a strong soft
excess in all the burst spectra. The excess emission can be characterized by
the use of a scaling factor (f_a method) to the persistent emission of the
source, which is attributed to the increased mass accretion rate on to the
neutron star due to Poynting-Robertson drag. The soft excess emission can also
be characterized by the use of a model taking into account the reflection of
the burst emission off of the accretion disk. We also present time resolved
spectral analysis of 5 X-ray bursts simultaneously observed by NICER and
AstroSat, which confirm the main results with even greater precision. Finally,
we present evidence for Compton cooling using 7 X-ray bursts observed
contemporaneously with \nustar, by means of a correlated decrease in the hard
X-ray lightcurve of 4U 1636-536 as the bursts start.
