Risks Related to Our Limited Operating History, Financial Position and Need For
Additional
Capital

capital to finance our
operations, which may not be available..., page 9

2.       We note your disclosure on page 103 of the prospectus that, under
certain circumstances
         where a future financing source is introduced to you by the
Representative, you have
         agreed to pay the Representative a cash fee equal to 8.0% of the
aggregate gross proceeds
         received by you from any financing or capital raising transaction of
any kind within the 12
         months following the effective date of the registration statement.
Please mention this tail
         compensation when discussing the possibility that you may need to seek
additional funds
         sooner than you currently plan.
Risks Related to the Development and Commercialization of Our Future Isotopes
We are early in our research and development efforts for Mo-100 and U-235 using
the ASP

3.       We refer to your disclosure here that you expect to complete the proof
of concept phase of
         the Mo-100 development plan during 2022 and your disclosure on pages
48 and 89 that
         the Company's management expects that it could take up to 15 months to
complete the
         initial proof of concept phase. Please reconcile these disclosures.

approval from the
         FDA, European Medicines Agency (EMA) or other comparable foreign
regulatory
         authorities prior to sale of Mo-100 and your disclosure on page 74
that some of your
         future isotopes "will also likely be regulated" by healthcare
regulators such as the Food
         and Drug Administration (FDA) in the USA, Health Canada in Canada, the
European
         Medicines Agency in Europe and similar regulators in other countries.
Please revise your
         disclosure here and throughout the prospectus to clearly state whether

         will need approval from regulatory authorities in order to
commercialize Mo-100. If you
         believe the need for regulatory approval is uncertain, please discuss
the specific reasons
         for this uncertainty, when and how a determination will be made and
the impact this
         uncertainty will have on your business and operations.
Risks Related to Our Intellectual Property
We may be unable to adequately protect our intellectual property and
proprietary rights and
prevent others from making unauthorized use..., page 16

5.       We note the disclosure in Note 8. License Agreements to the
Consolidated Financial
         Statements on page F-13 that under the Mo-100 and U-235 license
agreements
         any development efforts improving the intellectual property performed
by either Klydon
         or the Company will be the property of Klydon. Please expand on your
disclosure in this
         risk factor to discuss any material risks regarding Klydon's ownership
of the intellectual
         property used in your business. Additionally, please reconcile the
fact that Klydon will
         retain ownership of the intellectual property with your statements on
page 20 of the
         prospectus that you anticipate you "will file patent applications both
in the United States
         and in other countries, as appropriate" and that you "intend to seek
to protect [your]
         proprietary position by filing patent applications in the United
States and abroad related to
         [your] current and future development programs and future isotopes to
the extent
         permitted by applicable law."
Risks Related to Regulatory Compliance
Our business is and could become subject to a wide variety of extensive and
evolving laws and
regulations. Failure to comply with such..., page 16

6.       We note your disclosure here that "[t]he design, construction and
operation of the Mo-
         100 enrichment plant are highly regulated and require government
licenses, approvals and
         permits, and may be subject to the imposition of conditions." We also
note references
         throughout the prospectus to the need to obtain "applicable regulatory
approvals." Please
         expand your disclosure here and elsewhere in the prospectus to briefly
explain the
         material governmental approvals you or Klydon need to build and
operate the plant,
         including the status and expected timing for applying for and/or
receiving such approvals.
Risks Related to Our Dependence on Third Parties
Klydon currently performs or supports many of our operating activities and will
continue to do
so after the closing of this offering..., page 24

7.       There are several references here and elsewhere in the prospectus to

disclosure to indicate
         how far in the development process you estimate that the allocated
proceeds from the
         offering will enable you to reach. For example, please indicate if you
expect to be able to
         fund the Phase 1, Phase 2 and/or commercialization phase of the Mo-100
development
         plan without raising additional capital or fund the acquisition of all
of the outstanding
         shares or substantially all of the assets of Klydon. In this regard,
we note your disclosure
         on page 9 of the prospectus that while you believe, based on your
current operating plan,
         that following the offering you will have sufficient cash on hand to
fund operations for at
         least the next 12 months you will require substantial additional
capital to support your
         business operations.

Mo-100 produced using ASP technology could support an alternative and
potentially more
convenient production route for Tc-99m, page 58

17.      We note your disclosure here that "[a]ssuming that the Mo-99 produced
from our Mo-
         100 is determined to be equivalent to currently available Mo-99 and
the technetium
         generator has already received regulatory approval with relevant
healthcare regulators, we
         believe this route to market will not require additional regulatory
approvals from the
         relevant healthcare regulator." Please expand on this disclosure to
explain which
         regulatory agency or agencies would need to determine that the Mo-99
produced from
         your Mo-100 is equivalent to currently available Mo-99 and the process
and expected

ASP technology.
