Determine whether the following actions cause the fission reaction in the reactor to speed up or slow down.
a. speeds up fission: Adding the moderator to the reactor
b. speeds up fission: Removing the control rods from the reactor
c. slows down fission: Inserting the control rods into the reactor
d. slows down fission: Removing the moderator from the reactor
e. slows down fission: A sudden loss of primary coolant water in a pressurized water reactor

Answer:

option B and C

Explanation:

Control rod are used to regulate the nuclear reactor.

When you insert control rod in the reactor it slows down the nuclear fission inside the reactor and the energy produced in the reactor will be less.

When you remove control road from the reactor the nuclear fission increase inside the reactor and the energy production is high.

Control rod consist of boron, boron absorb the neutron which help to control the nuclear fission.

Hence, the correct answer is option B and C
