  As J. Visch just tell you, something like (you must change armB too if you
want a shorter loopsize):

    \ncloop[angleA=90,angleB=180,loopsize=-2,armA=0.5,armB=0,linearc=.2]{->}{B}{B}

but straightforwardly, as you do not need the five segments of a loop here:

    \ncangles[angleA=90,angleB=180,arm=0.5,linearc=.2]{->}{B}{B}

  You can look at these variations:

\documentclass{article}

\usepackage{pst-node}

\pagestyle{empty}

\begin{document}

\psframebox[framesep=0]{%
\begin{pspicture}(-1,-1)(1,1)
    \rnode{B}{\psframebox{On a actionn\'e $k_1$}}
    \ncangles[angleA=90,angleB=180,arm=0.5,linearc=.2]{->}{B}{B}
\end{pspicture}}

\psframebox[framesep=0]{%
\begin{pspicture}(-1,-1)(1,1)
    \rnode{B}{\psframebox{On a actionn\'e $k_1$}}
    \ncloop[angleA=90,angleB=180,loopsize=-2,armA=0.5,armB=0,linearc=.2]{->}{B}{B}
\end{pspicture}}

\psframebox[framesep=0]{%
\begin{pspicture}(-1,-1)(1,1)
    \rnode{B}{\psframebox{On a actionn\'e $k_1$}}
    \ncloop[angleA=90,angleB=180,loopsize=2,arm=0.5,linearc=.2]{->}{B}{B}
\end{pspicture}}

\psframebox[framesep=0]{%
\begin{pspicture}(-1,-1)(1,1)
    \rnode{B}{\psframebox{On a actionn\'e $k_1$}}
    \ncloop[angleA=90,angleB=-90,loopsize=2,arm=0.5,linearc=.2]{->}{B}{B}
\end{pspicture}}

\psframebox[framesep=0]{%
\begin{pspicture}(-1,-1)(1,1)
    \rnode{B}{\psframebox{On a actionn\'e $k_1$}}
    \ncloop[angleA=90,angleB=-90,loopsize=-2,arm=0.5,linearc=.2]{->}{B}{B}
\end{pspicture}}

\end{document}
