Reactor Bui_lding Entries.
The third reactor building (RB) entry (entry 19) in support.of the gross decontamination experiment was completed on Thursday, November 5,1981.
During the first three entries, housekeeping and trash removal were the most time consuming 1
tasks in the RB.. Surveys in accessible areas of the RB have not l
detected any radiological changes which could be attributed to the transfer of 205,000 gallons of water from the R8 basement to the l
SDS.
l Three of the four scheduled gross decontamination experiment entries l
have'been completed.
However, the schedule for specific tasks has I
fallen ~behind in several areas.
Delays in work to install the high l
pressture water hose, the power lift, new radio antennas, and electrical,

- Meetings Held
~
A meeting was. held on November 3,1981, by B. Snyder with Maryland State f
Delegate Catherine Riley to brief her on TMI-2 cleanup progress and future plans.
Delegate Riley represents the ~ area of Maryland which includes the Susquehanna River and the head of the Cheasapeake Bay. She
.[
has had a continuing interest in TMI-2, including active participation /
h in NRC public meetings held ~in Maryland on the Programmatic Environmental Impact Statement.
In addition to a discussion of the current status of' TMI-2 cleanup activities, Delegate Riley was briefed on future NRC f
studies for further investigation of alternatives for disposition of processed accident water and assessments of potential socio-economic h*
impacts associated with each alternative.
Planned State of. Maryland studies of socio-economic impacts of processed accident water disposition 3
were also discussed.
