No estimate has been made of the cost of the Defence Nuclear Enterprise for calendar year 2019. Information on forecast costs for financial years 2018/19 and 2019/20 can be found in figure 12 of the National Audit Office's landscape review of the Enterprise published on 22 May 2018, which is available at the following link:

The Ministry of Defence does not, and has no plans to, routinely publish whole life costs for projects, nuclear or otherwise, beyond what is already published in reports such as the Defence Equipment Plan, Ministry of Defence Annual Report and Accounts, and the Infrastructure and Projects Authority's Annual Report on Major Projects.
