From G3PLX:


I don't think the presence of the spurious emission (near 60kHz) from the LORAN transmitter would cause any trouble to MSF itself. A quick calculation says that the nearest spurii from the Rugby LORAN transmitter to the MSF transmission would be respectively 8.9139804 Hz low and 5.94265 Hz high of 60kHz, and probably a long long way down on the main 60kHz carrier.

The accuracy of MSF is 2 parts in 10E12, so systematic interference even a long long way down may well have an effect. It will depend on the design of the receiver and whether it has a front end filter that has high rejection at +6Hz, -8Hz, but prior to the LORAN transmitter.
