 Monday, October 05, 2015, 15:25, Isaac Earle, Standard Operation, Other, Other, Old T2 Protect Monitor Cassette Update
|
The T2 protect monitor cassette removed in April 2015 (see E-log #154) was surveyed today. It was approximately 3mSv/hr at 0.5m and 15mSv/hr
on contact. It is unlikely that this monitor will ever be cool enough for hands-on elevation adjustment that it requires, therefore it has been bagged,
labeled, and transferred to the east hot cell for storage. |

|
To address the deficiencies identified in E-Logs #204 and #205 the old active sump high level switch was replaced with Omega LV164SS model (316SS stem
and float, 4' length, standard mount) using adaptor flange TRH1316 to mount to the top flange of the sump. A new electrical box was also installed
(circuit diagram attached in PDF format). The circuit was designed by Don Jackson and wired by Travis Cave. Connection to the RCR Lab PLC was |

Wednesday, March 15, 2017, 16:13, Isaac Earle, Standard Operation, Other, Active Sump, Meson Hall Hot Cell Lab Active Sump Water Released
|
On March 13th in the morning the Meson Hall Hot Cell Lab active sump reached the high level sensor. The system responded as expected: high
level panel warning light illuminated, siren sounded, and MCR notified via "B1 RCR1 RM6 WARN". A 1L sample was delivered to RPG for analysis.
After approval, the sump was pumped out over the following two days. The procedure in Document #64834 was followed for sampling and pump-out. |
