I have had 1 Rosa Rugosa bush for 3 years that has never bloomed. What could be wrong? What could be the problem as it grows and appears healthy.

It could be not enough sunlight and could be the rose fertilizer used is too high in nitrogen. Here are some links to articles for you to check out: https://www.gardeningknowhow.com/ornamental/flowers/roses/no-blooms-on-roses.htm
Also check the pH level of the soils as too high a pH will cause them not to bloom.
