Like this:

<input type="checkbox" name="UKSC" value="checkbox"
    tal:attributes="checked some_boolean_expression">

Note that the checked attribute is optional.  This also works

<input type="checkbox" name="UKSC" value="checkbox" checked
    tal:attributes="checked some_boolean_expression">

And so does this:
<input type="checkbox" name="UKSC" value="checkbox" checked="1"
    tal:attributes="checked some_boolean_expression">

I really do not like the last form, though.  In fact, 
<input type="checkbox" name="UKSC" value="checkbox" 
    checked="Holy, sweet babaloo"
    tal:attributes="checked some_boolean_expression">
works.

In all cases, the actual output will be something like:
<input type="checkbox" name="UKSC" value="checkbox" checked="checked">
for a checked item, and 
<input type="checkbox" name="UKSC" value="checkbox"> 
for an unchecked item.
